    This review will summarize the effectiveness of computed tomography, ultrasound, and nuclear medicine imaging procedures in several different disease processes. The results indicate: (1) CT is clearly better than ultrasound for diseases of the adrenal gland and pancreas; (2) for patients with gynecologic malignancies, CT and ultrasound are approximately equivalent in their ability to define treatment options effectively; (3) in the liver, the differences among the three modalities are less marked and are disease specific. For example, for patients with colon cancer the increased effectiveness of CT relative to ultrasound or nuclear medicine is small. For patients with breast cancer, the difference is greater; (4) for patients suspected to have a focal source of sepsis, CT is slightly better than ultrasound or nuclear medicine. In these patients, however, when nuclear medicine images are obtained on a rectilinear scanner, the results are significantly worse compared to nuclear medicine images on a LFOV gamma camera or to ultrasound. As a result of the above studies and concommitant statistical analyses, several conclusions can be drawn about optimum experimental design and statistical approaches for comparing imaging modalities

    To define the policy of our specialty with a consensus opinion, a questionnaire entitled 'hybrid imaging' was sent to practicing nuclear medicine specialist physicians in France to obtain their opinion on the impact of this recent method in training and in the practice of nuclear medicine and on the relations between nuclear medicine specialists and other medical imaging specialists. This questionnaire, written by the office of the French Society of Nuclear Medicine (F.S.N.M.) and molecular imaging, was divided into four parts: Profile and experience in hybrid imaging, Relations with radiologists, Practice of CT scans with hybrid equipment, and the Future of the specialty and of training in nuclear medicine. The response rate was 60%, i.e. 374 completed questionnaires. Overall, the responses were uniform, whatever the respondent's experience, type and place of practice. Regular participation in hybrid imaging practice was the reply provided by the majority of respondents. In terms of relations with radiologists, such contacts existed in over 85% of cases and are considered as being of high quality in over 90% of cases. The vast majority of practitioners believe that hybrid imaging will become the standard. Opinions on the diagnostic use of CT scans are divided, as well as their interpretation by a radiologist, a nuclear medicine specialist or by both. In the opinion of the vast majority, hybrid equipment systems should be managed by nuclear medicine specialists. With regard to the future, nuclear medicine should remain an independent specialty with enhanced training in morphological imaging and a residency training program whose length should be increased to 5 years.

    Positron emission tomography (PET) is a new modality that is gaining use in nuclear medicine. The use of PET and computed tomography (CT) has grown dramatically. Because of the high energy of the annihilation radiation (511 keV), shielding requirements are an important consideration in the design of a PET or PET/CT imaging facility. The goal of nuclear medicine and PET facility shielding design is to keep doses to workers and the public as low as reasonably achievable (ALARA). Design involves: 1. Calculation of doses to occupants of the facility and adjacent regions based on projected layouts, protocols and workflows, and 2. Reduction of doses to ALARA through adjustment of the aforementioned parameters. The radiological evaluation of a PET/CT facility consists of the assessment of the annual effective dose both to workers occupationally exposed, and to members of the public. This assessment takes into account the radionuclides involved, the facility features, the working procedures, the expected number of patients per year, and so on. The objective of the study was to evaluate shielding requirements for a PET/CT to be installed in the department of nuclear medicine of Bangladesh Atomic Energy Commission (BAEC). Minimizing shielding would result in a possible reduction of structural as well as financial burden. Formulas and attenuation coefficients following the basic AAPM guidelines were used to calculate un-attenuated radiation through shielding materials. Doses to all points on the floor plan are calculated based primarily on the AAPM guidelines and include consideration of broad beam attenuation and radionuclide energy and decay. The analysis presented is useful for both, facility designers and regulators. (author)

  6. Clinical applications of SPECT/CT: New hybrid nuclear medicine imaging system

    International Nuclear Information System (INIS)

    2008-08-01

    Interest in multimodality imaging shows no sign of subsiding. New tracers are spreading out the spectrum of clinical applications and innovative technological solutions are preparing the way for yet more modality marriages: hybrid imaging. Single photon emission computed tomography (SPECT) has enabled the evaluation of disease processes based on functional and metabolic information of organs and cells. Integration of X ray computed tomography (CT) into SPECT has recently emerged as a brilliant diagnostic tool in medical imaging, where anatomical details may delineate functional and metabolic information. SPECT/CT has proven to be valuable in oncology. For example, in the case of a patient with metastatic thyroid cancer, neither SPECT nor CT alone could identify the site of malignancy. SPECT/CT, a hybrid image, precisely identified where the surgeon should operate. However SPECT/CT is not just advantageous in oncology. It may also be used as a one-stop-shop for various diseases. Clinical applications with SPECT/CT have started and expanded in developed countries. It has been reported that moving from SPECT alone to SPECT/CT could change diagnoses in 30% of cases. Large numbers of people could therefore benefit from this shift all over the world. This report presents an overview of clinical applications of SPECT/CT and a relevant source of information for nuclear medicine physicians, radiologists and clinical practitioners. This information may also be useful for decision making when allocating resources dedicated to the health care system, a critical issue that is especially important for the development of nuclear medicine in developing countries. In this regard, the IAEA may be heavily involved in the promotion of programmes aimed at the IAEA's coordinated research projects and Technical Cooperation projects

    Purpose: Development of an adapted multidisciplinary procedure designed to optimize the clinical workflow between radiation therapy (RT) and nuclear medicine (NM) for a PET-CT located in the NM department. Methods : The radiation oncologist (RO) prescribes the PET-CT exam and the clinical RT therapist gives all the necessary information to the patient prior to the exam. The immobilization accessories are prepared in the RT department. The RT and NM therapists work together for radiotracer injection, patient positioning and scan acquisition. The nuclear medicine physician (NMP) will study the images, draw Biological Target Volumes (BTVs) and produce a full exam report. Results : All tasks related to a planning PET-CT are done within 48 hours from the request by the RO to the reception of the images with the NMP contours and report. Conclusions : By developing a complete procedure collectively between the RT and NM departments, the patient benefits of a quick access to a RT planning PET-CT exam including the active involvement of every medical practitioners in these fields.

    2017-12-01

    This article discusses the role of PET/CT in contributing to precision medicine in lung cancer, and provides the perspective of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) on this process. The mission and vision of SNMMI are listed, along with the guidance provided by SNMMI to promote best practice in precision medicine. Basic principles of PET/CT are presented. An overview of the use of PET/CT imaging in lung cancer is discussed. In lung cancer patients, PET/CT is vitally important for optimal patient management. PET/CT is essential in determining staging and re-staging of disease, detecting recurrent or residual disease, evaluating response to therapy, and providing prognostic information. PET/CT is also critically important in radiation therapy planning by determining the extent of active disease, including an assessment of functional tumor volume. The current approach in tumor imaging is a significant advance over conventional imaging. However, recent advances suggest that therapeutic response criteria in the near future will be based on metabolic characteristics and will include the evaluation of biologic characteristics of tumors to further enhance the effectiveness of precision medicine in lung cancer, producing improved patient outcomes with less morbidity.

    The CNEA and the IDB are running for the second time the Distance Assisted Training course (DAT-OL), which is part of a global program of the International Atomic Energy Agency (IAEA) for Nuclear Medicine technologists working in centers equipped with PET CT and / or SPECT-CT hybrids. Aims: Completion of this course is justified by the strong increase in the installation of hybrid nuclear medicine (NM) systems, the increasing demand for qualified technicians and the lack of formal training opportunity. The course objective is to both promote the qualification of the technologist as improving quality and operational safety in MN participating centers. Material and Methods: This new course is free and is taught in Spanish from the www.datnmt.org website. The study material is available on site and the training is aided by tutors of institutions as CNEA, FUESMEN (School of Nuclear Medicine Foundation), UBA (University of Buenos Aires) and Nuclear Medicine private labs. The DAT-OL is developed in modules: Physics of SPECT / CT and PET / CT; Principles and sectional anatomy CT, SPECT / CT and PET / CT clinical; cyclotron and radiopharmaceutical production; Radiation Safety in PET / CT; Workflows and protocols with PET / CT, clinical reports: normal variants, artifacts and failures. Some of the requirements to take the DAT-OL are: Access to camera PET / CT and / or camera SPECT / CT, and a supervisor (Nuclear Medicine physician or Medical physicist) at the center of NM where the student works. Technicians must have academic qualification, 5 or more years working in centers MN, previous courses in Biology, Physics SPECT and SPECT Clinical course and a Methodology of Radioisotopes and radiation protection course. Results: The first course lasted 12 months including examinations. Tutors have scarcely been consulted. SPECT/CT and PET/CT web examinations, have been developed and evaluated by the authors of the course (B. Hutton and H. Patterson, University of London and

  10. Dynamic CT for Parathyroid Adenoma Detection: How Does Radiation Dose Compare With Nuclear Medicine?

    Dynamic CT is increasingly used for preoperative localization of parathyroid adenomas, but concerns remain about the radiation effective dose of CT compared with that of 99m Tc-sestamibi scintigraphy. The purpose of this study was to compare the radiation dose delivered by three-phase dynamic CT with that delivered by 99m Tc-sestamibi SPECT/CT performed in accordance with our current protocols and to assess the possible reduction in effective dose achieved by decreasing the scan length (i.e., z-axis) of two phases of the dynamic CT protocol. The effective dose of a 99m Tc-sestamibi nuclear medicine parathyroid study performed with and without coregistration CT was calculated and compared with the effective dose of our current three-phase dynamic CT protocol as well as a proposed protocol involving CT with reduced scan length. The median effective dose for a 99m Tc-sestamibi nuclear medicine study was 5.6 mSv. This increased to 12.4 mSv with the addition of coregistration CT, which is higher than the median effective dose of 9.3 mSv associated with the dynamic CT protocol. Reducing the scan length of two phases in the dynamic CT protocol could reduce the median effective dose to 6.1 mSv, which would be similar to that of the dose from the 99m Tc-sestamibi study alone. Dynamic CT used for the detection of parathyroid adenoma can deliver a lower radiation dose than 99m Tc-sestamibi SPECT/CT. It may be possible to reduce the dose further by decreasing the scan length of two of the phases, although whether this has an impact on accuracy of the localization needs further investigation.

  17. Nuclear medicine in gynecologic oncology: Recent practice

    1987-01-01

    Nuclear medicine tests tell more about the physiological function of an organ that about its anatomy. This is in contrast to several other modalities in current use in the field of diagnostic imaging. Some of these newer modalities, such as computerized tomography (CT), offer a better resolution of the anatomy of the organ being examined. This has caused physicians to drift away from certain nuclear medicine tests, specifically those that focus primarily on the anatomy. When CT scanning is available, for instance, it is no longer advisable to perform a scintigraphic brain scan in search of metastasis;CT scanning is more accurate overall and more likely than a nuclear study to result in a specific diagnosis. In certain cases of diffuse cortical infections like herpes encephalitis, however, a scintiscan is still superior to a CT scan. Today's practice of nuclear medicine in gynecologic oncology may be divided into the three categories - (1) time-tested function-oriented scintiscans, (2) innovations of established nuclear tests, and (3) newer pathophysiological scintistudies. The author discusses here, briefly, each of these categories, giving three examples of each

    Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive materials to examine organ function and structure. Nuclear medicine is older than CT, ultrasound and MRI. It was first used in patients over 60-70 years ago. Today it is an established medical specialty and offers procedures that are essential in many medical specialities like nephrology, pediatrics, cardiology, psychiatry, endocrinology and oncology. Nuclear medicine refers to medicine (a pharmaceutical) that is attached to a small quantity of radioactive material (a radioisotope). This combination is called a radiopharmaceutical. There are many radiopharmaceuticals like DTPA, DMSA, HIDA, MIBI and MDP available to study different parts of the body like kidneys, heart and bones etc. Nuclear medicine uses radiation coming from inside a patient's body where as conventional radiology exposes patients to radiation from outside the body. Thus nuclear imaging study is a physiological imaging, whereas diagnostic radiology is anatomical imaging. It combines many different disciplines like chemistry, physics mathematics, computer technology, and medicine. It helps in diagnosis and to treat abnormalities very early in the progression of a disease. The information provides a quick and accurate diagnosis of wide range of conditions and diseases in a person of any age. These tests are painless and most scans expose patients to only minimal and safe amounts of radiation. The amount of radiation received from a nuclear medicine procedure is comparable to, or often many times less than, that of a diagnostic X-ray. Nuclear medicine provides an effective means of examining whether some tissues/organs are functioning properly. Therapy using nuclear medicine in an effective, safe and relatively inexpensive way of controlling and in some cases eliminating, conditions such as overactive thyroid, thyroid cancer and arthritis. Nuclear medicine imaging is unique because it provides doctors with

    Imaging forms an important part of nuclear medicine and a number of different imaging devices have been developed. This chapter describes the principles and technological characteristics of the main imaging devices used in nuclear medicine. The two major categories are gamma camera systems and positron emission tomography (PET) systems. The former are used to image γ rays emitted by any nuclide, while the latter exploit the directional correlation between annihilation photons emitted by positron decay. The first section of this chapter discusses the principal components of gamma cameras and how they are used to form 2-D planar images as well as 3-D tomographic images (single photon emission computed tomography (SPECT)). The second section describes related instrumentation that has been optimized for PET data acquisition. A major advance in nuclear medicine was achieved with the introduction of multi-modality imaging systems including SPECT/computed tomography (CT) and PET/CT. In these systems, the CT images can be used to provide an anatomical context for the functional nuclear medicine images and allow for attenuation compensation. The third section in this chapter provides a discussion of the principles of these devices.

    The purpose of this study was to assess the radiation exposure to nuclear medicine staff at a positron emission tomography-computed tomography (PET-CT) centre with high patient throughput. This prospective study included 70 adult patients who underwent 18F-fluorodeoxyglucose (FDG) PET-CT for their clinical indications. The patients' actual injected FDG activity was calculated by subtracting the syringe activity (post-injection) from the loaded syringe activity (pre-injection). The instantaneous exposure to nuclear medicine staff involved in PET-CT imaging was measured. The instantaneous dose rate of the physicians was recorded during FDG injection and that of the technologist was recorded during the patient's positioning, respectively, at 1.0-m distance from the anterior chest using a calibrated portable gamma-ray survey meter. The average FDG activity injected in adult patients was 308.5 MBq (range 173.1-438.8 MBq). The instantaneous exposure to the nuclear medicine (NM) physician during the injection time was 31 μSv/h (14-60 μSv/h). The instantaneous exposure to the NM technologist during positioning was 18 (10-34) μSv/h. With an average of 10 patients per day, the quarterly dose to physicians was 628 μSv and to technologists 182 μSv for 300 patients. The extrapolated annual dose was 2.5 mSv for physicians and 0.7 mSv for technologists, respectively. Instantaneous exposure of nuclear medicine staff involved in PET-CT imaging at a busy tertiary care centre is within permissible limits of the International Commission on Radiological Protection (ICRP-103) (total 50 mSv in a single year) and atomic energy regulatory board (total 30 mSv in a single year).

    As we all know, Nuclear Medicine is the medical science using nuclear radiation for diagnosis, treatment and research. Nuclear Medicine, in contrast to Radiology, makes use of unsealed sources of radiation. Nuclear Medicine a few years ago has partly offered Nuclear Cardiology, the most lucrative of all Nuclear Medicine "children" at that time, to Cardiology. Radiology, has succeeded in being recognized by the European Union Authorities as Clinical Radiology. The word "clinical" offers greater independence to Clinical Radiology and makes it difficult for such a specialty to relinquish any of its equipment i.e. the diagnostic CT scan or the newly developed fast angiography CT, to other specialties. Contrary to Clinical Radiology, Nuclear Medicine being a laboratory specialty in most countries seems to have no right to deny offering, after some period of "proper certified education", its PET camera to Clinical Radiologists. Nuclear Medicine by virtue of its unique diagnostic techniques and treatments, is and should be recognized as a "Clinical Specialty" The interference of other specialties in the fields of Nuclear Medicine is also indicated by the fact that in vitro techniques of Nuclear Medicine are often used by Endocrinologists and Oncologists in their own laboratories. Also in some hospitals the Director of the Radiology Department acts as the Director of Nuclear Medicine Laboratory. Finally at present, Radiologists wish after "proper certified education", to be on equal terms in charge of the new hybridic equipment, the PET/CT scanner. If that is followed to happen, Nuclear Medicine will be in a difficult position losing at least part of PET and consequently should ask for help from its "Overlords and Protectors" i.e. the National and the European Societies of Nuclear Medicine and the Society of Nuclear Medicine of the United States of America. Radiology as a specialty participating om equal terms with the PET camera will then include the study of: a) "open

    During the past few years, there have been new impulses in the development of a number of technologies employed in Nuclear Medicine imaging. These include new scintillation materials, the way of detecting the scintillation light, and completely novel methods to detect gamma rays by means of semiconductor detectors. In addition to combined instrumentation that can be used for SPECT and PET, already in clinical use, combined scintigraphic and anatomic imaging devices are now becoming available, for example SPECT/CT or PET/CT. This review article describes the most important of the new components, part of which have already entered product development and part of which are still in the research phase.

    Accurate cardiovascular imaging is essential for the successful management of patients with congenital heart disease (CHD). Echocardiography and angiography have been for long time the most important imaging modalities in pediatric cardiology, but nuclear medicine has contributed in many situations to the comprehension of physiological consequences of CHD, quantifying pulmonary blood flow symmetry or right-to-left shunting. In recent times, remarkable improvements in imaging equipments, particularly in multidetector computed tomography and magnetic resonance imaging, have led to the progressive integration of high resolution modalities in the clinical workup of children affected by CHD, reducing the role of diagnostic angiography. Technology has seen a parallel evolution in the field of nuclear medicine, with the advent of hybrid machines, as SPECT/CT and PET/CT scanners. Improved detectors, hugely increased computing power, and new reconstruction algorithms allow for a significant reduction of the injected dose, with a parallel relevant decrease in radiation exposure. Nuclear medicine retains its distinctive capability of exploring at the tissue level many functional aspects of CHD in a safe and reproducible way. The lack of invasiveness, the limited need for sedation, the low radiation burden, and the insensitivity to body habitus variations make nuclear medicine an ideal complement of echocardiography. This is particularly true during the follow-up of patients with CHD, whose increasing survival represent a great medical success and a challenge for the health system in the next decades. Metabolic imaging using 18 FDG PET/CT has expanded its role in the management of infection and inflammation in adult patients, particularly in cardiology. The same expansion is observed in pediatric cardiology, with an increasing rate of studies on the use of FDG PET for the evaluation of children with vasculitis, suspected valvular infection or infected prosthetic devices.

    Aim: Currently, the German and Austrian S3 guidelines on the evaluation and treatment of lung cancer are about to be published whereas the American Colleague of Chest Physicians (ACCP) guidelines were already presented in 2007. An important part of the diagnostic workup of lung cancer will be the evaluation of indeterminate lung lesions and the mediastinal and extrathoracic staging using FDG-PET or PET/CT. The results from the literature on FDG-PET and PET/CT as well as on conventional nuclear medicine staging procedures and the clinical implications are presented. Methods: The literature data was amassed in analogy to the metaanalyses drawn for the current ACCP guidelines. In addition, relevant more recent publications were also considered. To answer the important question for the extent of pathological confirmation needed, the residual risk of mediastinal metastases was calculated for certain constellations of FDG-PET and CT findings. Suggested recommendations were characterized with the level of evidence. Results: FDG-PET (PET/CT) allows the differentiation of indeterminate lung lesions with high accuracy. FDG-PET (PET/CT) is the most accurate non-invasive procedure to assess the mediastinal nodal stage, for non-small cell as well as for small cell lung cancer. It is justified to omit invasive evaluation of enlarged but FDG-PET negative lymph nodes under certain circumstances. Unexpected extrathoracic metastases detected by FDG-PET imply important changes in therapeutic management. Conclusion: The upcoming S3 guideline on lung cancer will recommend FDG-PET in several indications due to its clinical efficacy well proven by data from literature (high level of evidence). The selected use of conventional nuclear medicine procedures remains beyond doubt. FDG-PET (PET/CT) belongs to the standard of care in lung cancer

    This paper presents the results of radiation level measurements at workplaces in a nuclear medicine facility performing PET/ CT examinations. This study meticulously determines the staff radiation exposure in a PET/CT facility by tracking the path of patient movement. The measurements of the instantaneous radiation exposure were performed using an electronic radiometer with a proportional counter that was equipped with the option of recording the results on line. The measurements allowed for visualisation of the staff's instantaneous exposure caused by a patient walking through the department after the administration of "1"8F-FDG. An estimation of low doses associated with each working step and the exposure during a routine day in the department was possible. The measurements were completed by determining the average radiation level using highly sensitive thermoluminescent detectors. (authors)

    Full Text Available Objective: Radiology information system (RIS is basically evolved for the need of radiologists and ignores the vital steps needed for a proper work flow of Nuclear Medicine Department. Moreover, CT/MRI oriented classical PACS systems are far from satisfying Nuclear Physicians like storing dynamic data for reprocessing and quantitative analysis of colored images. Our purpose was to develop a workflow based Nuclear Medicine Information System (NMIS that fulfills the needs of Nuclear Medicine Department and its integration to hospital PACS system. Material and Methods: Workflow in NMIS uses HL7 (health level seven and steps include, patient scheduling and retrieving information from HIS (hospital information system, radiopharmacy, acquisition, digital reporting and approval of the reports using Nuclear Medicine specific diagnostic codes. Images and dynamic data from cameras of are sent to and retrieved from PACS system (Corttex© for reprocessing and quantitative analysis. Results: NMIS has additional functions to the RIS such as radiopharmaceutical management program which includes stock recording of both radioactive and non-radioactive substances, calculation of the radiopharmaceutical dose for individual patient according to body weight and maximum permissible activity, and calculation of radioactivity left per unit volume for each radionuclide according their half lives. Patient scheduling and gamma camera patient work list settings were arranged according to specific Nuclear Medicine procedures. Nuclear Medicine images and reports can be retrieved and viewed from HIS. Conclusion: NMIS provides functionality to standard RIS and PACS system according to the needs of Nuclear Medicine.

    In nuclear medicine, single-photon-emission computed tomography (SPECT) is often combined with ‘simultaneous’ low-dose CT (LDCT) to provide complementary anatomical and functional correlation. As a consequence, numerous incidental and unexpected findings may be detected on LDCT. Recognition of these findings and appropriate determination of their relevance can add to the utility of SPECT/CT. We aimed to evaluate the prevalence and categorise the relevance of incidental and unexpected findings on LDCT scans performed as part of routine SPECT/CT studies. All available LDCT scans performed as part of SPECT/CT studies at St. Vincent's Hospital Melbourne in the year 2013 were retrospectively reviewed. Two qualified radiologists independently reviewed the studies and any previous available imaging and categorised any detected incidental findings. A total of 2447 LDCT studies were reviewed. The relevance of the findings was classified according to a modified version of a scale used in the Colonography Reporting and Data System: E1 = normal or normal variant (28.0%); E2 = clinically unimportant (63.5%); E3 = likely unimportant or incompletely characterised (6.2%); E4 = potentially important (2.5%). Imaging specialists need to be cognisant of incidental and unexpected findings present on LDCT studies performed as part of SPECT/CT. Appropriate categorisation of findings and communication of potentially important findings to referring clinicians should form part of routine practice. The overall prevalence of potentially significant incidental and unexpected findings in our series was 8.7% (E3, 6.2%; E4, 2.5%) and was comparable to rates in other published imaging series.

    Objective: To evaluate the status of nuclear medicine department in Beijing area. Methods: Staff, equipment and clinical applications of nuclear medicine departments in Beijing area during 2005 were evaluated by postal questionnaires. Results: Thirty nuclear medicine departments responded to our survey. In these departments, 321 staff, 141 doctors, 122 technicians, 7 physicists, 22 nurses and 29 other staff were employed; and 41 large imaging equipments, 37 SPECT, 3 PET, 1 PET-CT were equipped. During 2005, 88135 radionuclide imaging (84734 for SPECT, 3401 for PET), 462246 radioimmunoassay and 2228 radionuclide therapies (the most for Graves' disease, the second for thyroid cancer, the third for bone metastasis) were performed. For only 41.5% and 22.0% equipments the daily quality control (QC) and weekly QC were conducted. Conclusions Staff, equipments and activities of nuclear medicine department in Beijing were in a considerable scale, but did not balance among hospitals. Most departments should increase the number of physicists and the equipment QC procedures to improve the image quality. (authors)

    For more than a half a century nuclear medicine is contributing in the field of medicine. Still nuclear medicine is not widely available in many countries. Especially in developing countries due to many a reasons nuclear medicine could not flourish in that way. Availability of radioisotope, high cost of instrument and sophistication of the branch are the three main reasons behind. Even the countries where nuclear medicine is functioning for quite a long time, the facilities for proper function are still not adequate. Training of manpower, maintenance of instruments, regular supply of isotopes and kit and cost effectiveness are some of the major problems. We have seen some fast developments in nuclear medicine in last few decades. Development of gamma detecting systems with SPECT, positron emission detector (PET), supported computer technology and introduction of some newer radiopharmaceuticals for functional studies are few of the examples. The developing countries also have a problem to go on parallel with these rapid development of nuclear medicine in other part of the world. In last few decades we have also witnessed development of CT, MRI, Ultrasound and other imaging modalities as our competitor. Specially for developing countries these have posed as a major challenge for nuclear medicine. A better understanding between developed and developing nations is the key point of todays ultimate success in any sector. For real development of nuclear medicine and to give the majority of the people the benefit of nuclear medicine a better and more active co-operation is needed between all the countries. The paper presents the difficulties and some practical problems of practicing nuclear medicine in a developing country. And also appeals for global co-operation to solve the problems for better interest of the subject

    Nuclear medicine imaging is generally based on the detection of X rays and γ rays emitted by radionuclides injected into a patient. In the previous chapter, the methods used to detect these photons were described, based most commonly on a scintillation counter although there are imaging devices that use either gas filled ionization detectors or semiconductors. Whatever device is used, nuclear medicine images are produced from a very limited number of photons, due mainly to the level of radioactivity that can be safely injected into a patient. Hence, nuclear medicine images are usually made from many orders of magnitude fewer photons than X ray computed tomography (CT) images, for example. However, as the information produced is essentially functional in nature compared to the anatomical detail of CT, the apparently poorer image quality is overcome by the nature of the information produced. The low levels of photons detected in nuclear medicine means that photon counting can be performed. Here each photon is detected and analysed individually, which is especially valuable, for example, in enabling scattered photons to be rejected. This is in contrast to X ray imaging where images are produced by integrating the flux entering the detectors. Photon counting, however, places a heavy burden on the electronics used for nuclear medicine imaging in terms of electronic noise and stability. This chapter will discuss how the signals produced in the primary photon detection process can be converted into pulses providing spatial, energy and timing information, and how this information is used to produce both qualitative and quantitative images.

    2009-01-01

    Full text:A 35 year old male presented, suffering from night sweats, occipital and frontal headaches, blurred vision, nausea and a decrease in appetite. He underwent a CT and MRI scan, which identified a 2.2cm lesion in the left orbit in an intra-conal position. This was suspected to be a cavernous haemangioma, although other tumours, such as Schwannoma could not be ruled out. A nuclear medicine labelled red blood cell study was performed which included initial dynamic images and early statics and 120min delayed images. SPECT/CT was also performed at the later time. The characteristic blood pool mismatch of low early and high delayed concentration of red blood cells confirmed suspicions of a cavernous haemangioma, which, although comprised mainly of blood vessels, has slow flow. Hence there is considerable delay before maximum activity is reached. The lesion was surgically removed. Histology reports confirmed the nuclear medicine results. Nuclear Medicine has the potential to play a significant role in the preoperative diagnosis of an orbital mass.

  10. A glance at the history of nuclear medicine

    International Nuclear Information System (INIS)

    Carlsson, S.

    1995-01-01

    The development of nuclear medicine has resulted in several effective routine methods in diagnosis and therapy. There is an ongoing discussion about the future of the activity based on the fast development of ultrasound, CT and MR. In such discussions, it is often forgotten that nuclear medicine is also a dynamic diagnostic tool under continuous progress. As seen from this historical review, nuclear medicine has grown from quite simple in vitro tests to very advanced methods to image organ function. This is the result of the development of radiopharmaceuticals and instrumentation. Today, development is moving towards what is called receptor scintigraphy, i.e., the use of radiopharmaceuticals which are very specific to certain diseases, for instance, tumours. Even at present there is no other method to determine the regional myocardial blood flow both at stress and at rest, than myocardial scintigraphy. Nuclear medicine will remain an important diagnostic tool as long as it employs people with engagement and interest. Such people will also guarantee that the hospital management will supply the activity with funds for the necessary investments. (orig.)

  11. Cardiac CT and cardiac MRI - competitive or complementary for nuclear cardiology

    International Nuclear Information System (INIS)

    Moshage, W.

    2004-01-01

    In summary, cardiac computed tomography (CT) and cardiac magnetic resonance (MR) are two different technologies with distinct imaging properties that gain increasing importance in clinical cardiology. Even though images may look similar, the areas of application of CT and MR are quite different. Clinical applications of cardiac CT focus on on-invasive imaging of the coronary arteries. In this respect, the higher spatial resolution of cardiac CT constitutes a significant advantage as compared to MR and clinical results are superior. Clinical applications of cardiac MR, next to morphologic imaging of the heart, are most frequently found in the context of intra-and pericardial masses, complex congenital anomalies, and the assessment of left ventricular function (dobutamine) and perfusion (adenosine) under stress. The evaluation of the size and localization of myocardial necrosis, scars, and fibrosis gains increasing importance, for example in the workup of myocardial infarction, but also myocarditis and cardiomyopathies. In this respect, magnetic resonance imaging partly constitutes an alternative to nuclear medicine methods. Due to the lack of ionizing radiation and a relatively high spatial resolution, an increase of MR diagnostic procedures at the expense of nuclear medicine can be expected. (orig.)

Nuclear technique offers facilities and chances related to research activities and services in medicine. The development of diagnostic as well as therapeutic methods using monoclonal antibodies labeled with radioisotope will undoubtedly play an important role in the disease control

    Nuclear medicine in cardiology was reviewed. Electrocardiogram is obtained from the ..gamma..-ray measurement of a tracer by a single detector, which enables a bedsidemonitoring. Resolution and sensitivity are high and nuclear stethoscope with a computer is applicable for a background treatment. Myocardium is imaged by /sup 201/Tl scintigraphy. Relative difference of the perfusion indicates the ischemia which gaives roughly the size and portion of myocardial infarction. For transient ischemia stress myocardial perfusion imaging (SMPI) is also used. sup(99m)Tc pyrophosphate provides a clear image for myocardial infarction. Angiocardiogram is obtained repeatedly, by a single administration, using an equilibrium method. An attempt of three-dimensional display by 7 pin hole collimator and positron CT are also discussed.

    The aim of this study is to estimate the whole body and finger radiation doses per study received by nuclear medicine staff involved in dispensing, administration of 18 F-FDG and interacting with radioactive patients during PET/CT imaging procedures in a PET/CT facility. The whole-body doses received by radiopharmacists, technologists and nurses were measured by electronic dosimeter and the finger doses by ring dosimeter during a period of 4 months. In 70 PET/CT studies, the mean whole-body dose per study to radiopharmacist, technologist, and nurse were 1.07±0.09, 1.77±0.46, μSv, and not detectable respectively. The mean finger doses per study received by radiopharmacist, technologist, and nurse were 265.65±107.55, 4.84±1.08 and 19.22±2.59 μSv, respectively. The average time in contact with 18 F-FDG was 5.88±0.03, 39.06±1.89 and 1.21±0.02 minutes per study for radiopharmacist, technologist and nurse respectively. Technologists received highest mean effective whole- body dose per study and radiopharmacist received the highest finger dose per study. When compared with the ICRP dose limit, each individual worker can work with many more 18 F- FDG PET/CT studies for a whole year without exceeding the occupational dose limits. This study confirmed that low levels of radiation does are received by our medical personnel involved in 18 F-FDG PET/CT procedures. (paper)

    The aim of this study is to re-evaluate and clarify the diagnostic role of ventilation/perfusion lung scintigraphy in Japan, now that single-detector-row helical CT and multidetector-row CT are available in clinical practice. The Respiratory Nuclear Medicine Working Group of the Japanese Society of Nuclear Medicine distributed a questionnaire to institutions in Japan equipped with scintillation cameras as of September 2001. Of 1,222 institutions, 239 returned effective answers (19.6%). The most frequent combination for initial diagnosis of acute pulmonary thromboembolism was chest radiography, perfusion lung scintigraphy, and contrast-enhanced CT (111 institutions, 46.4%). The questionnaire revealed that the validity and usage of perfusion lung scintigraphy and those of contrast-enhanced CT were equivalent in the present clinical situation. On the other hand, the diagnostic value of ventilation lung scintigraphy in suspected pulmonary thromboembolism has not been established in Japan. Even though contrast-enhanced CT is widely used in Japan, perfusion lung scintigraphy is still required to determine disease severity and monitor its progress. (author)

  2. MO-AB-207-00: ACR Update in MR, CT, Nuclear Medicine, and Mammography

    International Nuclear Information System (INIS)

    2015-01-01

    A goal of an imaging accreditation program is to ensure adequate image quality, verify appropriate staff qualifications, and to assure patient and personnel safety. Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up-to-date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, computed tomography, nuclear medicine, and mammography. Each speaker will discuss the general components of the modality program and address any recent changes to the requirements. Learning Objectives: To understand the requirements of the ACR MR Accreditation program. The discussion will include accreditation of whole-body general purpose magnets, dedicated extremity systems well as breast MRI accreditation.

    A goal of an imaging accreditation program is to ensure adequate image quality, verify appropriate staff qualifications, and to assure patient and personnel safety. Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up-to-date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, computed tomography, nuclear medicine, and mammography. Each speaker will discuss the general components of the modality program and address any recent changes to the requirements. Learning Objectives: To understand the requirements of the ACR MR Accreditation program. The discussion will include accreditation of whole-body general purpose magnets, dedicated extremity systems well as breast MRI accreditation. Anticipated updates to the ACR MRI Quality Control Manual will also be reviewed. To understand the requirements of the ACR CT accreditation program, including updates to the QC manual as well as updates through the FAQ process. To understand the requirements of the ACR nuclear medicine accreditation program, and the role of the physicist in annual equipment surveys and the set up and supervision of the routine QC program.

    The development of imaging techniques like SPECT, SPECT-CT, PET, PET-CT and MRT has advanced rapidly during the past few years, especially in the case of hybrid technology. These techniques have become indispensable in diagnosis, differential diagnosis, therapy follow-up and prevention. This 6th revised and edited version of 'Nuclear Medicine' takes account of these developments. The general section presents fundamentals of physics, radiopharmaceutical chemistry, measuring techniques, nuclear medical examination techniques, and dosimetry. The special section presents detailed descriptions of all relevant nuclear medical techniques by organ systems and clinical pictures. There are many examples and scintiscans of organs to train the diagnostic eye and give a link to clinical practice. This successful textbook presents complex subject matter in a clear and intelligible way. It addresses newcomers and expert doctors that require training in nuclear medical methods. It has also become a standard textbook in university medicine studies and in the training of radiological assistants. (orig.)

    Nuclear medicine studies evaluate physiology on a molecular level providing earlier detection of lesions before morphologic change is evident. 99m Tc-MDP and 18 F-fluoride bone scans detect osteomyelitis earlier than radiographs and computed tomography (CT); aid in diagnosis of temporomandibular joint disorder; and evaluate activity of condylar hyperplasia, extent of Paget disease, and viability of bone grafts. 18 F-FDG PET/CT distinguish between soft tissue and bone infections and diagnose osteomyelitis complicated by fracture or surgery. FDG PET is more accurate than CT alone and has a major role in staging, restaging, and assessing response to therapy for head and neck malignancies and in detecting sequelae of therapy.

    2007-01-01

    In the same way that the symptoms between different diseases in psychiatry overlap, functional brain research frequently shows the same pattern of changes across diagnostic borders; on the other hand, many the other tests, e.g. psychological tests, present the same problem as mentioned above; therefore: The psychiatrist seldom applies to an NM specialist to obtain a diagnosis; instead, a nuclear medicine report will rather confirm, or less frequently exclude, the psychiatrist's diagnosis. Ideally, psychiatric patients should be rescanned after the treatment, and changes in perfusion and/or metabolism discussed between psychiatrist and NM specialist. As shown above, there are few practical applications of nuclear medicine due to low specificity and low spatial resolution, although in the aspect of functional imaging it is still superior to CT/MRI, even in their functional modalities. On the other hand, its investigational potential is still growing, as there is no imaging technique in sight which could replace metabolic and receptor studies, and also because the scope of functional imaging in psychiatric diseases is spreading from its traditional applications, like dementia or depression, towards many poorly investigated fields e.g. hypnosis, suicidal behaviour or sleep disorders.

    Full text: The diagnostic workup of acute Winter Sports injuries is done by Conventional X Ray, CT and MRI. Chronic injuries as stress reactions are best investigated by Nuclear Medicine procedures: Snow Boarding: In Snow-Boarding chronic injuries are mostly seen as local increased uptake laterally in the lower third of the Fibula of the front leg together with Tibial increase medially in the other leg. Skiing: Chronic Skiing injuries are less asymmetrical and mostly seen on the apex of the patella. Chronic Feet Problems: A different chronic problem is the reduced blood perfusion in the feet if hard, tightened boots are used for longer time by professional ski instructors and racers. Flow difference between the foot in the boot and the other without boot are dramatic as measured by Nuclear Medicine Procedures and MRI. Pulmonary Embolism: Acute pulmonary embolism caused by thrombi originating at the site of constant pressure on the back rim of ski boots is not uncommon in older skiers (seek and you will find), but never seen in the younger group of Snow-Boarders.

    Nuclear Medicine is a medical specialty that uses radionuclides for the diagnosis and treatment of diseases and it is one of the most important peaceful applications of nuclear sciences. Nuclear Medicine has a short history both in Turkey and in the world. The first use of I-131 for the treatment of thyrotoxicosis in Turkey was in 1958 at the Istanbul University Cerrahpasa Medical School. In 1962, Radiobiological Institute in Ankara University Medical School was established equipped with well-type counters, radiometers, scalers, external counters and a rectilinear scanner. In 1965, multi-probe external detection systems, color dot scanners and in 1967, anger scintillation camera had arrived. In 1962, wet lab procedures and organ scanning, in 1965 color dot scanning, dynamic studies (blood flow - renograms) and in 1967 analogue scintillation camera and dynamic camera studies have started. In 1974, nuclear medicine was established as independent medical specialty. Nuclear medicine departments have started to get established in 1978. In 1974, The Turkish Society of Nuclear Medicine (TSNM) was established with 10 members. The first president of TSNM was Prof. Dr. Yavuz Renda. Now, in the year 2000, TSNM has 349 members. Turkish Society of Nuclear Medicine is a member of European Association of Nuclear Medicine (EANM), World Federation of Nuclear Medicine and Biology (WFNMB) and WFNMB Asia-Oceania. Since 1974, TSNM has organized 13 national Nuclear Medicine congresses, 4 international Nuclear Oncology congresses and 13 nuclear medicine symposiums. In 1-5 October 2000, 'The VII th Asia and Oceania Congress of Nuclear Medicine and Biology' was held in Istanbul, Turkey. Since 1992, Turkish Journal of Nuclear Medicine is published quarterly and it is the official publication of TSNM. There are a total of 112 Nuclear Medicine centers in Turkey. There are 146 gamma cameras. (52 Siemens, 35 GE, 16 Elscint, 14 Toshiba, 10 Sopha, 12 MIE, 8 Philips, 9 Others) Two cyclotrons are

    ECT is a mathematical and physical concept, an instrument, a radionuclide tracer technique, a research procedure and it is certainly both an old (Kuhl began his work in the late fifties) and a new concept. It also has great and unique potential as a diagnostic technique. It is interesting that the basic principles of medical CT were exemplified and developed in Nuclear Medicine by Kuhl and coworkers and the concept of ''physiologic or function tomography'' provides a technique to advance the original charter of Nuclear Medicine in the use of radionuclides for the measure of metabolism and physiologic function

    This guidebook for clinical nuclear medicine is written as a description of how nuclear medicine procedures should be used by clinicians in evaluating their patients. It is designed to assist medical students and physicians in becoming acquainted with nuclear medicine techniques for detecting and evaluating most common disorders. The material provides an introduction to, not a textbook of, nuclear medicine. Each chapter is devoted to a particular organ system or topic relevant to the risks and benefits involved in nuclear medicine studies. The emphasis is on presenting the rationales for ordering the various clinical imaging procedures performed in most nuclear medicine departments. Where appropriate, alternative imaging modalities including ultrasound, computed tomography imaging, and radiographic special procedures are discussed. Comparative data between nuclear medicine imaging and other modalities are presented to help guide the practicing clinician in the selection of the most appropriate procedure for a given problem.

    The final step in a medical imaging procedure is to display the image(s) on a suitable display system where it is presented to the medical specialist for diagnostic interpretation. The display of hard copy images on X ray film or photographic film has largely been replaced today by soft copy image display systems with cathode ray tube (CRT) or liquid crystal display (LCD) monitors as the image rendering device. Soft copy display requires a high quality display monitor and a certain amount of image processing to optimize the image both with respect to the properties of the display device and to some psychophysiological properties of the human visual system. A soft copy display system, therefore, consists of a display workstation providing some basic image processing functions and the display monitor as the intrinsic display device. Display devices of lower quality may be used during intermediate steps of the acquisition and analysis of a patient study. Display monitors with a quality suitable for diagnostic reading by the specialist medical doctor are called primary devices, also known as diagnostic devices. Monitors with lower quality but good enough to be used for positioning, processing of studies, presentation of images in the wards, etc. are referred to as secondary devices or clinical devices. Nuclear medicine images can be adequately displayed even for diagnostic purposes on secondary devices. However, the increasing use of X ray images on which to report jointly with images from nuclear medicine studies, such as those generated by dual modality imaging, notably by positron emission tomography (PET)/computed tomography (CT) and single photon emission computed tomography (SPECT)/CT, requires display devices capable of visualizing high resolution grey scale images at diagnostic quality, i.e. primary display devices. Both grey scale and colour display devices are used, the latter playing an important role in the display of processed nuclear medicine images and

    SPECT/CT has represented not only the possibility of acquiring anatomical and functional images in one single study, but also a revolution for the clinical management of several diseases, taking the better of each one of these imaging modalities. The present work is aimed at presenting an overview of the most important applications of the SPECT/CT in the field of oncology, cardiology and neurology. New technological advances in the design of innovative solid state detectors and related equipment have had a positive effect on the performance of this kind of dual modality. This hybrid technique improves the sensitivity and the specificity of gammagraphic studies, as well as shortens the acquisition times and gives attenuation correction of co-registered images, which, in turn, makes their analysis easier. Some of the main applications for the study of oncological diseases are the following: localization and follow-up of different kinds of tumors, their metastasis and relapses, as well as the optimization of radiotherapy doses. This technique has been useful to evaluate the coronary artery disease allowing an adequate attenuation correction of images, the determination of calcium score, and performing angio-CT studies, according to the CT quality. SPECT/CT has also gained ground in the assessment of some neurological diseases. Conclusions: The introduction of new technological advances and radiopharmaceuticals thus predicting a more relevant place for SPECT/CT in clinical practice. (author)

    The field of nuclear medicine is undergoing rapid expansion, and is evolving into diagnostic molecular imaging. During recent years, dual-modality imaging with PET/CT has gained acceptance and this is currently the fastest-growing technique for oncological imaging applications. The glucose analogue FDG has held its place in diagnostic oncology, assessment of myocardial viability and diagnosis of neuro-degenerative disorders. Peptides have become even more important as imaging agents. The accuracy of hepatobiliary scintigraphy has been enhanced by cholecystokinin. The use of ACE inhibitors in the evaluation of renovascular hypertension has become the standard in renography. New instrumentation has led to faster scanners, and computer development to better image processing software. Automatic processing is more common, and standardization of protocols can be accomplished easily. The field of gene imaging has progressed, although routine clinical applications are not yet available. The present text, supplemented with many detailed and informative illustrations, represents an adjunct to the standard knowledge of diagnostic nuclear medicine and provides both the student and the professional with an overview of developments during the past decade.

    PACS (Picture Archiving and Communication System) is being rapidly spread and installed in many hospitals, but most of the system do not include nuclear medicine field. Although additional costs of hardware for nuclear medicine PACS is low, the complexity in developing viewing software and little market have made the nuclear medicine PACS not popular. Most PACS utilize DICOM 3.0 as standard format, but standard format in nuclear medicine has been Interfile. Interfile should be converted into DICOM format if nuclear images are to be stored and visualized in most PACS. Nowadays, many vendors supply the DICOM option in gamma camera and PET. Several hospitals in Korea have already installed nucler PACS with DICOM, but only the screen captured images are supplied. Software for visualizing pseudo-color with color lookup tables and expressing with volume view should be developed to fulfill the demand of referring physicians and nuclear medicine physicians. PACS is going to integrate not only radiologic images but also endoscopic and pathologic images. Web and PC based PACS is now a trend and is much compatible with nuclear medicine PACS. Most important barrier for nuclear medicine PACS that we encounter is not a technical problem, but indifference of investor such as administrator of hospital or PACS. Now it is time to support and invest for the development of nuclear medicine PACS

    The aim of this study is to provide information on developing technologies and clinical techniques for Hybrid SPECT/CT imaging using ionizing radiation and their associated radiation dose to patients and medical staff. A thermoluminescent dosimeters (TLD) was used in this study to analyze the historic records of the external radiation doses to staff members working in our nuclear medicine department in 7 procedures, including elution of 99mTc from "9"9"mMo/"9"9"mTc generators, syringe preparation, radiopharmacy kit preparation, injection, accompanying patients, SPECT/CT scan, oral "1"3"1I preparation. These dosimeters was worn by the staff members at the level of the chest on the front part of the body. A retrospective review of 110 clinical studies of various nuclear medicine procedures ("9"9"mTc–MIBI–Tetrofosmin, "9"9"mTc–MDP bone scan, "9"9"mTc–Tektrotyd, "9"9"mTc–Thyroid imaging, "9"9"mTc–Nanocoll, "1"3"1I–Nal (diagnostic application 185 MBq) obtained on hybrid SPECT/CT systems was performed to calculate the effective radiation dose to patients. The results from this study showed that annual effective radiation doses to nuclear medicine department staff members were within permissible levels. The contribution of total effective radiation dose from SPECT component were calculated using the activity of the injected radiopharmaceutical and dose tables published by the conversion factors listed in ICRP 53 and ICRP 80. The radiation dose for CT was calculated by Dose Length Product method. According to the results of this study the dose in each procedure depends on different factors such as the education and experience of the staff members, usage of shielding and taking the radiation protection requirements into consideration. When SPECT–CT is being performed, all measures should be taken to reduce both the radiopharmaceutical dose and the CT effective dose following the ALARA principle. (author)

    Anatomical imaging modalities including CT and MRI are the mainstay of evaluation of primary pheochromocytoma or paraganglioma. However, nuclear medicine imaging is frequently necessary to determine the nature of the lesions. The purpose of this investigation is to assess which commonly used nuclear medicine modality might have a better diagnostic value in this clinical setting. Eight patients who had been suspected of having either primary pheochromocytoma or primary paraganglioma and 1 patient with known pheochromocytoma were included in the analysis. Among the 8 patients without known diagnosis, 7 had been suggested by anatomical imaging modalities, whereas one of them presented with initial negative anatomical imaging interpretation. All of 9 patients underwent Ga-DOTATATA PET/CT, FDG PET/CT, and MIBG SPECT/CT for further evaluation. The imaging findings were compared with postsurgical pathology and follow-up. Both Ga-DOTATATA PET/CT and MIBG SPECT/CT accurately identified 9 primary tumors, whereas FDG PET/CT showed increased activity in 8 of 9 primary tumors. Both Ga-DOTATATA and FDG PET/CT are able to detect associated extra-adrenal lesions not shown on MIBG study in patients with multiple endocrine neoplasia syndrome. Ga-DOTATATA PET/CT could be the nuclear medicine imaging choice to evaluate suspected primary pheochromocytoma or paraganglioma, especially in the situation of multiple endocrine neoplasia syndrome.

    With the development of medical science, monitoring dynamic biologic processes in small-animal models of diseases has become one of the most important approaches in medical studies. Important physiologic parameters that traditionally have been characterized by nuclear medicine imaging include blood flow, biochemical metabolism, and cellular receptors. Recently, nuclear medicine has been greatly facilitated by the newer development of dual-modality integrated imaging systems (SPECT-CT and PET-CT), which provide functional and anatomical images in the same scanning session, with the acquired images co-registered by means of the hardware. The purpose of this review is to compare SPECT-CT with PET-CT in several applications of small-animal models. Conclusicn: PET-CT for small animal modes in nledical research in the applications has great advantages, but SPECT-CT is still a very important role, and research low cost. (authors)

    After 5 y of collecting data on diagnostic reference levels (DRLs), the Nuclear Safety and Radiation Protection French Inst. (IRSN) presents the analyses of this data. The analyses of the collected data for radiology, computed tomography (CT) and nuclear medicine allow IRSN to estimate the level of regulatory application by health professionals and the representativeness of current DRL in terms of relevant examinations, dosimetric quantities, numerical values and patient morphologies. Since 2004, the involvement of professionals has highly increased, especially in nuclear medicine, followed by CT and then by radiology. Analyses show some discordance between regulatory examinations and clinical practice. Some of the dosimetric quantities used for the DRL setting are insufficient or not relevant enough, and some numerical values should also be reviewed. On the basis of these findings, IRSN formulates recommendations to update regulatory DRL with current and relevant examination lists, dosimetric quantities and numerical values. (authors)

    The purpose of this review is not to present a comprehensive description of all the mathematical tools used in nuclear medicine, but to emphasize the importance of the mathematical method in nuclear medicine and to elucidate some of the mathematical concepts currently used. We can distinguish three different areas in which mathematical support has been offered to nuclear medicine: Physiology, methodology and data processing. Nevertheless, the boundaries between these areas can be indistinct. It is impossible in a single article to give even an idea of the extent and complexity of the procedures currently usede in nuclear medicine, such as image processing, reconstruction from projections and artificial intelligence. These disciplines do not belong to nuclear medicine: They are already branches of engineering, and my interest will reside simply in revealing a little of the elegance and the fantastic potential of these new `allies` of nuclear medicine. In this review the mathematics of physiological interpretation and methodology are considered together in the same section. General aspects of data-processing methods, including image processing and artificial intelligence, are briefly analysed. The mathematical tools that are most often used to assist the interpretation of biological phenomena in nuclear medicine are considered; these include convolution and deconvolution methods, Fourier analysis, factorial analysis and neural networking.

    Nuclear cardiology is no longer a medical discipline residing solely in nuclear medicine. This is the first book to recognize this fact by integrating in-depth information from both the clinical cardiology and nuclear cardiology literature, and acknowledging cardiovascular medicine as the fundamental knowledge base needed for the practice of nuclear cardiology. The book is designed to increase the practitioner's knowledge of cardiovascular medicine, thereby enhancing the quality of interpretations through improved accuracy and clinical relevance.The text is divided into four sections covering all major topics in cardiology and nuclear cardiology: -Basic Sciences and Cardiovascular Diseases; -Conventional Diagnostic Modalities; -Nuclear Cardiology; -Management of Cardiovascular Diseases.

    The history, present status, and possible future of nuclear medicine are presented. Beginning with development of the rectilinear scanner and gamma camera, evolution to the present forms of hybrid technology such as single photon emission computed tomography/computed tomography (CT) and positron emission tomography/CT is described. Both imaging and therapy are considered and the recent improvements in dose estimation using hybrid technologies are discussed. Future developments listed include novel radiopharmaceuticals created using short chains of nucleic acids and varieties of nanostructures. Patient-specific radiotherapy is an eventual outcome of this work. Possible application to proving the targeting of potential chemotherapeutics is also indicated

    Nuclear medicine techniques have a long history in pulmonary medicine, one that has been continually changing and growing. Even longstanding methods, such as perfusion scanning for embolic disease or for pretherapy pulmonary function evaluation, have largely withstood the test of recent careful scrutiny. Not only have these techniques remained an important part of the diagnostic armamentarium, but we have learned how to use them more effectively. Furthermore, because of technical advances, we are in a phase of expanding roles for nuclear imaging. Gallium citrate scanning for the mediastinal staging and follow-up of lymphoma has been recognized as a valuable adjunct to the anatomic information provided by CT and MRI. With the growth of PET technology in areas that have been explored in a limited fashion until now, such as noncardiogenic pulmonary edema and lung carcinoma, evaluation and management of these patients may substantially improve. Finally, in the field of radiolabeled monoclonal antibodies, attention is now being turned to both the diagnostic and the therapeutic problems presented by lung carcinoma. As radiolabeling methods are refined and as new and better antibodies are developed, radioimmunodetection and therapy in lung carcinoma may begin to make inroads on this common and hard to control disease.157 references

    The role of a procedure depends not only on its own capabilities but also on a cost/effective comparison with alternative technique giving similar information. Starting from the definition of emergency as a sudden unexpected occurrence demanding immediate action, the role of nuclear medicine (NM) is difficult to identify if it is not possible to respond 24h a day, 365 days a year, to clinical demands. To justify a 24 h NM service it is necessary to reaffirm the role in diagnosis of pulmonary embolism in the spiral CT era, to spread knowledge of the capabilities of nuclear cardiology in reliability diagnosis myocardial infraction (better defining admission and discharge to/from the emergency department), to increase the number of indications. Radionuclide technique could be used as first line, alternative, complementary procedures in a diagnostic tree taking into account not only the diagnosis but also the connections with prognosis and therapy in evaluating cerebral pathologies, acute inflammation/infection, transplants, bleeding, trauma, skeletal, hepatobiliary, renal and endocrine emergencies, acute scrotal pain

    The strength of nuclear medicine lies in using the tracer method to acquire information about how an organ is or is not functioning as it should. This modality, therefore, focuses on physiological organ function for diagnoses and not on anatomical information such as X ray computed tomography (CT) or magnetic resonance imaging. The three aspects involved in the process are: (i) choice of radioactive tracer, (ii) method of detection of the emissions from the tracer, and (iii) analysis of the results of the detection. The radioactive tracers on which nuclear medicine (or molecular imaging as it is increasingly being called) is based are designed to participate in or ‘trace’ a chosen function of the body. Their distribution is then found by detecting and locating the emissions, usually γ photons, of the radioactive tracer. The tracer may be involved in a metabolic process, such as iodine in the thyroid, or it may take part in a physiological process because of its physical make-up, such as macroaggregate of albumin (MAA) in the lungs.

  1. The 8th questionnaire survey report of safety control in nuclear medicine

    International Nuclear Information System (INIS)

    2008-01-01

    A questionnaire survey on safety of nuclear medicine studies was conducted under the subcommittee for radionuclide imaging and nuclear medicine technology of Japan Radioisotope Association to promote patient safety. Questionnaires were sent to 1300 hospitals and 21 clinical laboratories in Japan with 1034 facilities responded (78.3%). Sixty percents of the workers in the facilities were nuclear medicine technologists. Medical doctors comprised 20% of the workers, but 32% in the university hospitals. The number of laboratory technologists decreased in all categories of the facilities. Composite PET/CT scanners increased sharply, whereas 2-detector and 3-detector imaging systems decreased. Regular maintenance was performed in approximately 80% of the SPECT imaging systems, while the single head imaging systems were maintained less frequently. Filmless systems were employed in 25.3% of all of the facilities responded, with the higher rate in the university hospitals. The number of accidents and incidents in the facilities decreased. Falls on floor and fall from an examination bed were reported. The nuclear medicine technologists were concerned about safety mechanism of imaging systems, and dimension and height of examination beds. They also wanted prompt supply of safety information and easy interconnectivity among different data of various vendors' systems. The results of this survey may be a valuable source of information on safety of nuclear medicine procedures. (author)

  2. Nuclear Medicine Engineering

    International Nuclear Information System (INIS)

    Mateescu, Gheorghe; Craciunescu, Teddy

    2000-01-01

    'An image is more valuable than a thousand words' - this is the thought that underlies the authors' vision about the field of nuclear medicine. The monograph starts with a review of some theoretical and engineering notions that grounds the field of nuclear medicine: nuclear radiation, interaction of radiation with matter, radiation detection and measurement, numerical analysis. Products and methods needed for the implementation of diagnostic and research procedures in nuclear medicine are presented: radioisotopes and radiopharmaceuticals, equipment for in-vitro (radioimmunoassay, liquid scintillation counting) and in-vivo investigations (thyroid uptake, renography, dynamic studies, imaging). A special attention is focused on medical imaging theory and practice as a source of clinical information (morphological and functional). The large variety of parameters, components, biological structures and specific properties of live matter determines the practical use of three-dimensional tomographic techniques based on diverse physical principles: single-photon emission, positron emission, X-rays transmission, nuclear magnetic resonance, ultrasounds transmission and reflection, electrical impedance measurement. The fundamental reconstruction algorithms i.e., algorithms based on the projection theorem and Fourier filtering, algebraic reconstruction techniques and the algorithms based on statistical principles: maximum entropy, maximum likelihood, Monte Carlo algorithms, are depicted in details. A method based on the use of the measured point spread function is suggested. Some classical but often used techniques like linear scintigraphy and Anger gamma camera imaging are also presented together with some image enhancement techniques like Wiener filtering and blind deconvolution. The topic of the book is illustrated with some clinical samples obtained with nuclear medicine devices developed in the Nuclear Medicine Laboratory of the National Institute of Nuclear Physics and

  5. Nuclear power in human medicine

    International Nuclear Information System (INIS)

    Kuczera, Bernhard

    2012-01-01

    The public widely associate nuclear power with the megawatt dimensions of nuclear power plants in which nuclear power is released and used for electricity production. While this use of nuclear power for electricity generation is rejected by part of the population adopting the polemic attitude of ''opting out of nuclear,'' the application of nuclear power in medicine is generally accepted. The appreciative, positive term used in this case is nuclear medicine. Both areas, nuclear medicine and environmentally friendly nuclear electricity production, can be traced back to one common origin, i.e. the ''Atoms for Peace'' speech by U.S. President Eisenhower to the U.N. Plenary Assembly on December 8, 1953. The methods of examination and treatment in nuclear medicine are illustrated in a few examples from the perspective of a nuclear engineer. Nuclear medicine is a medical discipline dealing with the use of radionuclides in humans for medical purposes. This is based on 2 principles, namely that the human organism is unable to distinguish among different isotopes in metabolic processes, and the radioactive substances are employed in amounts so small that metabolic processes will not be influenced. As in classical medicine, the application of these principles serves two complementary purposes: diagnosis and therapy. (orig.)

    Ndirangu, T.D.

    2017-01-01

    Nuclear medicine is a medical specialty that relies on the use of nuclear technology in the diagnosis and treatment (therapy) of diseases. Nuclear medicine uses the principle that a certain radiopharmaceutical (tracer) will at a certain point in time have a preferential uptake by a particular body, tissue or cell. This uptake is then imaged by the use of detectors mounted in gamma cameras or PET (positron emission tomography) devices.. Unlike other radiation applications for medical use, nuclear medicine uses open (unsealed) sources of radiation. In a country with an estimated population of 48 million in 2017, Kenya has only two (2) nuclear medicine facilities (units). Being a relatively new medical discipline in Kenya, several measures have been taken by the clinical nuclear medicine team to create awareness at various levels

    Full text: Aids patients are liable to more than one medical problem at anyone time as the number of CD4 cells decrease and the viral load increases. Problems are related to multiple causes of opportunistic Infections, malignant lymphoma and Kaposi sarcoma. Laboratory tests, sputum analysis and bronchial lavage have problems of decreased sensitivity. morphologic Imaging modalities such as chest X-ray, CT or MRI has problems of specificity. Nuclear medicine techniques has the advantage of total body functional imaging that can visualize more than one organ. The use nuclear medicine imaging is recommended when the diagnosis is uncertain and for initiation of proper treatment. Gallium-67 citrate total body scans acquired at 4 hours following the IV injection and at 24-48 hours has been very useful for the early diagnosis of opportunistic infections such as PCP, TB, Disseminated Mycobacterium avii complex; MAI, malignant lymphoma and various forms of AIDS related colitis. Sequential thallium and gallium scan help to differentiate Kaposi sarcoma (thallium positive, gallium negative) from opportunistic infections (gallium positive, thallium negative) and malignant lymphoma (thallium and gallium positive). Gallium is the most convenient radiopharmaceutical for the diagnosis of malignant lymphoma of the heart. Thallium and Tc-99m Sestamibi are useful for the differentiation of intracranial toxoplasmosis from malignant lymphoma. The presentation will illustrate different examples and will explain the limitations of all these tests. (author)

    Radiopharmaceuticals, drugs containing a radionuclide, are used routinely in nuclear medicine departments for the diagnosis of disease and are under investigation for use in the treatment of disease. Nuclear medicine takes advantage of both the nuclear properties of the radionuclide and the pharmacological properties of the radiopharmaceutical. Herein lies the real strength of nuclear medicine, the ability to monitor biochemical and physiological functions in vivo. This review discusses the coordination chemistry that forms the basis for nuclear medicine applications of the FDA-approved radiopharmaceuticals that are in clinical use, and of the most promising diagnostic and therapeutic radiopharmaceuticals that are in various stages of development. 232 refs

    1991-01-01

    The contribution of pulmonary nuclear medicine was evaluated in 115 patients with interstitial pulmonary diseases (IPD). Ventilation study (V) with 81m Kr or 133 Xe, distribution of compliance in thoraco-pulmonary system (C) by 81m Kr gas bolus inhalation method, perfusion study (Q) with 99m Tc-MAA, 67 Ga scintigraphy and an assessment of pulmonary epithelial permeability with 99m Tc-DTPA aerosol were performed as nuclear medicine procedures. Pulmonary function test (%DLco, vital capacity, and functional residual capacity) and blood gas analysis were also examined. Abnormalities in V were larger than that in Q, which was high V/Q mismatch finding, in interstitial pneumonia. Correlation between V/Q mismatch and PaO 2 was, therefore, not significant. %DLco was decreased in cases with larger V/Q mismatches. 67 Ga accumulated in the early stage of interstitial pneumonia when CT or chest X-ray did not show any finding. %DLco was decreased in cases with strong accumulation of 67 Ga. 67 Ga might be useful to evaluate activity of the disease. Pulmonary epithelial permeability was assessed by 99m Tc-DTPA inhalation study. This permeability became accelerated in idiopathic interstitial fibrosis and sarcoidosis. Pulmonary epithelial permeability may be useful as an indicator for epithelial cell injury. (author)

    A brief review is presented of the expanding horizons of nuclear medicine, the equipment necessary for a nuclear medicine laboratory is listed, and the value of this relatively new field to the veterinary clinician is indicated. Although clinical applications to veterinary medicine have not kept pace with those of human medicine, many advances have been made, particularly in the use of in vitro techniques. Areas for expanded applications should include competitive protein binding and other in vitro procedures, particularly in connection with metabolic profile studies. Indicated also is more intensive application by the veterinarian of imaging procedures, which have been found to be of such great value to the physician. (U.S.)

    1989-01-01

    Aspects of radiation protection in nuclear medicine and the role of the Dutch Society for Nuclear Medicine in these are discussed. With an effective dose-equivalence of averaged 3 mSv per year per nuclear medical examination and about 200.000 examinations per year in the Netherlands, nuclear medicine contributes only to a small degree to the total averaged radiation dose by medical treating. Nevertheless from the beginning, besides to protection of environment and personnel, much attention has been spent by nuclear physicians to dose reduction with patients. Replacing of relatively long living radionuclides like 131 I by short living radionuclides like 99m Tc is an example. In her education and acknowledgement policy the Dutch Society for Nuclear Medicine spends much attention to aspects of radiation reduction. (author). 3 tabs

    Full text of publication follows: Potential environmental dose rates in a patient waiting room at the PET/CT Imaging Center within our Nuclear Medicine Department (N.M.D.) are evaluated by both of the computer modeling method and real-time monitoring in practical settings. The maximum dose rate is directly read from a peak dose-rate frozen-up, digital gamma G-M survey meter. The design basis of our PET/CT Imaging Center facility has assumed a maximum total of five 18 FDG-patients presented at any given time either in an Am or a Pm session according to two separated drug batch delivering runs. Due to the relatively high gamma energy of 511 keV emitted by the F- 18 labeled compound, we have remodeled our facility with a 0.5-cm thick Pb wall and larger space separations between rooms that include a PET/CT scan room, two separated 18 FDG i.v. injection rooms, and a delayed-phase patient waiting room. Patient could normally complete two separate PET/CT scan runs, if a delayed-phase scan is needed, within three hours time frame from an initial dose of 370 MBq (10 mCi) that has a physical half-live of 110 minutes for an F-18 labeled compound. When all the needed scans are finished, the patient is released from our PET/CT Imaging Center that has to follow the radiation safety guideline of less than 50 mSv/hr (5 m R/hr) at one meter distance. During typical operation, each drug i.v. injection room or the scan room is restricted to one patient access only. As a worst case scenario, the maximum ambient dose rate may only occur when two or more delayed phase patients would stay in the PET/CT waiting room that is excluded for other non-PET patient use. Theoretically using a computer discrete-ordinate integrating methods, dose rates at one meter distance from a mid-point geometry, based on a simulated 10 mCi F-18 point, line or volumetric source (assuming 170 cm in height and 20 cm in radius of homogeneous water media), can also be calculated to give values of 5.71, 4.73 and 3

    Full text: A number of advances in diverse fields of science and technology and the fruitful synchronization of many a new development to address the issues related to health care in terms of prognosis and diagnosis resulted in the availability of host of modern diagnostic tools in medicine. Nuclear medicine, a unique discipline in medicine is one such development, which during the last four decades has seen exponential growth. The unique contribution of this specialty is the ability to examine the dynamic state of every organ of the body with the help of radioactive tracers. This tracer application in nuclear medicine to monitor the biological molecules that participate in the dynamic state of body constituents has led to a whole new approach to biology and medicine. No other technique has the same level of sensitivity and specificity as obtained in radiotracer technique in the study of in-situ chemistry of body organs. As modem medicine becomes oriented towards molecules rather than organs, nuclear medicine will be in the forefront and will become an integral part of a curative process for regular and routine application. Advances in nuclear medicine will proceed along two principal lines: (i) the development of improved sensitive detectors of radiation, powerful and interpretable data processing, image analysis and display techniques, and (ii) the production of exotic and new but useful radiopharmaceuticals. All these aspects are dealt with in detail in this talk

    Nuclear medicine is concerned with the utilisation of radioactivity in vivo or in vitro for diagnostic or therapeutic purposes. In Tunisia, there are four public departments of nuclear medicine and seven private clinics. 50% of the population is localized in the north, which justifies the existence of 7 public and private departments of nuclear medicine with nine gamma cameras in this region. In the south, there are 30 pour cent of the population that goes to Sfax and 20 pour cent to Sousse where we count two departments with gamma cameras in public services and one in the private sector. The nuclear medicine services in the public sector have 4 SPECT / CT. Siemens is the leading provider of gamma cameras and occupies 73 pour cent of market share, subsequently ranks SMV (13 pour cent) and (GE and GAEDE) have the same proportion of the market share (7 pour cent). For radio-protected rooms, there is a single center with a single chamber from four public services. On the other hand, there are 2/7 private centers that are equipped with five radio-protected electrically rooms. Concerning the human resources, there are 26 doctors and 24 technicians in the public sector. The private sector has 6 doctors and 12 technicians. In 2012, there has been 22000 examinations (diagnostic and therapeutic procedures) in which 14,600 in nuclear medicine departments of public hospitals. Bone scintigraphy ranks first, with a relative frequency of 40-80 pour cent thereafter ranks renal scintigraphy (10-15 pour cent) and then the thyroid scintigraphy (8-12 pour cent). The waiting period is a major problem, especially in the public sector. Taking as an example, for the therapy of thyroid, injection of 100 mCi of I-131 requires a period of waiting more than six months and waiting more than three months for the bone scan. The second problem for patient with cancer is the distance, there are 11 centers concentrated in 3 coastal cities and none in the inner areas of the country, no regional

    The background to the introduction and application of radioisotopes in medicine culminating in the establishment of the nuclear Medicine Unit at the Korle Bu Teaching Hospital, Ghana, has been examined. The Unit has been involved in important clinical researches since early 1970s but routine application in patient management has not always been possible because of cost per test and lack of continuous availability of convertible currency for the purchase of radioisotopes which are not presently produced by the National Nuclear Research Institute at Kwabenya. The capabilities and potentials of the Unit are highlighted and a comparison of Nuclear Medicine techniques to other medical diagnostic and imaging methods have been made. There is no organised instruction in the principles of medical imaging and diagnostic methods at both undergraduate and postgraduate levels in Korle Bu Teaching Hospital which has not promoted the use of Nuclear Medicine techniques. The development of a comprehensive medical diagnostic and imaging services is urgently needed. (author). 18 refs., 3 tabs

    2003-01-01

    In the past, consideration was given to the categories of nuclear medicine ranging from simple imaging or in-vitro laboratories, to more complex departments performing a full range of in-vitro and in-vivo procedures that are also involved in advanced clinical services, training programmes, research and development. In developing countries, nuclear medicine historically has often been an offshoot of pathology, radiology or radiotherapy services. These origins are currently changing as less radioimmunoassay is performed and fully-fledged, independent departments of nuclear medicine are being set up. The trend appears to be that all assays (radioassay or ELISA) are done in a biochemistry laboratory whereas nuclear medicine departments are involved largely in diagnostic procedures, radionuclide therapy and non-imaging in-vitro tests. The level of nuclear medicine services is categorized according to three levels of need: Level 1: Only one gamma camera is needed for imaging purposes. The radiopharmaceutical supply, physics and radiation protection services are contracted outside the centre. Other requirements include a receptionist and general secretarial assistance. A single imaging room connected to a shared reporting room should be sufficient, with a staff of one nuclear medicine physician and one technologist, with back-up. This level is appropriate for a small private practice. Level 2: This is suitable for a general hospital where there are multiple imaging rooms where in-vitro and other non-imaging studies would generally be performed as well as radionuclide therapy. Level 3: his is appropriate for an academic institution where there is a need for a comprehensive clinical nuclear medicine service, human resource development and research programmes. Radionuclide therapy for in-patients and outpatients is provided

    Nuclear medicine is a sector of the medicine that studies and applies radionuclide in diagnosis and therapy. Nuclear medicine is a very specific area of the medicine, making use of non-sealed radioactive sources which are prescribed to the patient orally or are injected. Special procedures in radiation protection are required in nuclear medicine to manipulate these kind of sources and to produce technetium-99m through molybdenum generator. The present paper addresses the them radiation protection in a Nuclear Medicine Department (NMD), showing the main requirements of the CNEN- National Commission of Nuclear Energy and the Public Health. Radiation protection procedures adopted in assembling a NMD, as well the daily techniques for monitoring and for individual dosimetry are discussed. Past and present analyses in a level of radiation protection are presented. (author)

    The branch of medical science that utilizes the nuclear properties of the radioactivity and stable nuclides to make diagnostic evaluation of anatomical and/or physiological conditions of the body and provide therapy with unsealed radioactive sources is called Nuclear Medicine (NM). The use of unsealed radionuclides in medicine is increasing throughout the world for diagnosis and treatment. As per UNSCEAR report more than 6 million nuclear medicine procedures are conducted in a year. However we know that radiation is double edged sword and if not used carefully will be harmful to patient as well as staff and therefore a nuclear medicine procedure should be undertaken only after proper justification and optimization. Nuclear medicine procedures are different than the X-ray diagnostic procedures as in NM, radioisotope is administered to patient and patient becomes radioactive. The NM staff is involved in unpacking radioactive material, activity measurements, storage of sources, internal transports of sources, preparation of radiopharmaceuticals, administration of radiopharmaceutical, examination of the patient, care of the radioactive patient, handling of radioactive waste and therefore receives radiation dose. This talk will discuss the various steps for radiation safety of patient, staff and public during Nuclear Medicine procedures so as to implementing the ALARA concept. (author)

  14. Nuclear Medicine Practice in Kenya

    Nuclear medicine is a medical specialty that relies on the use of nuclear technology in the diagnosis and treatment (therapy) of diseases. Nuclear medicine uses the principle that a certain radiopharmaceutical (tracer) will at a certain point in time have a preferential uptake by a particular body, tissue or cell. Unlike other radiation applications for medical use, nuclear medicine uses open (unsealed) sources of radiation. The tracer is introduced into the body of the patient through several routes (oral, intravenous, percutaneous, intradermally, inhalation, intracapsular etc) and s/he becomes the source of radiation. Early diagnosis of diseases coupled with associated timely therapeutic intervention will lead to better prognosis. In a country with an estimated population of 42 million in 2017, Kenya has only two (2) nuclear medicine facilities (units) that is Kenyatta National Hospital - Public facility and Aga Khan University Hospital which is a Private facility. Being a relatively new medical discipline in Kenya, several measures have been taken by the clinical nuclear medicine team to create awareness at various levels. Kenya does not manufacture radiopharmaceuticals. We therefore have to import them from abroad and this makes them quite expensive, and the process demanding. There is no local training in nuclear medicine and staff have to be sent abroad for training, making this quite expensive and cumbersome and the IAEA has been complimenting in this area. With concerted effort by all stakeholders at the individual, national and international level, it is possible for Kenya to effectively sustain clinical nuclear medicine service not only as a diagnostic tool in many disease entities, but also play an increasingly important role in therapy

    Nuclear medicine as a complex diagnostical method is used mainly to detect functional organic disorders, to locate disorders and for radioimmunologic assays (RIA) in vitro. In surgery, its indication range comprises the thyroid (in vivo and in vitro), liver and bile ducts, skeletal and joint diseases, disorders of the cerebro-spinal liquor system and the urologic disorders. In the early detection of tumors, the search for metastases and tumor after-care, scintiscanning and the tumor marcher method (CEA) can be of great practical advantage, but the value of myocardial sciritiscanning in cardiac respectively coronary disorders is restricted. The paper is also concerned with the radiation doses in nuclear medicine. (orig.) [de

    The last two decades have seen a significant increase in the demand for medical radiation services following the introduction of new techniques and technologies that has led to major improvements in the diagnosis and treatment of human diseases. The diagnostic and therapeutic applications of nuclear medicine techniques play a pivotal role in the management of these diseases, improving the quality of life of patients by means of an early diagnosis allowing opportune and proper therapy. On the other hand, inappropriate or unskilled use of these technologies can result in potential health hazards for patients and staff. So, there is a need to control and minimize these health risks and to maximize the benefits of radiation in medicine. The present study aims to discuss the role of nuclear medicine technology knowledge and scales in improving the management of patients, and raising the awareness and knowledge of nuclear medicine staff regarding the use of nuclear medicine facilities. The practical experience knowledge of nuclear medicine staff in 50 medical centers was reviewed through normal visiting and compared with the IAEA Published documents information. This review shows that the nuclear medicine staff has good technology knowledge and scales during managing patients as compared to IAEA Published information regarding the radiation protection measures and regulation. The outcome of the study reveals that competent authority can improve radiation safety in medical settings by developing and facilitating the implementation of scientific evidence-based policies and recommendations covering nuclear medicine technology focusing in the public health aspects and considering the risks and benefits of the use of radiation in health care. It could be concluded that concerted and coordinated efforts are required to improve radiation safety, quality and sustain ability of health systems

    Nuclear medicine began to be developed in the USA after 1938 when radionuclides were introduced into medicine and in Europe after radionuclides began to be produced at the Harwell reactor (England, 1947). Slovenia began its first investigations in the 1950s. This article describes the development of nuclear medicine in Slovenia and Ljubljana. The first nuclear medicine interventions were performed in Slovenia at the Internal Clinic in Ljubljana in the period 1954–1959. In 1954, Dr Jože Satler started using radioactive iodine for thyroid investigations. In the same year, Dr Bojan Varl, who is considered the pioneer of nuclear medicine in Slovenia, began systematically introducing nuclear medicine. The first radioisotope laboratories were established in January 1960 at the Institute of Oncology and at the Internal Clinic. Under the direction of Dr. Varl, the laboratory at the Internal Clinic developed gradually and in 1973 became the Clinic for Nuclear Medicine with departments for in vivo and in vitro diagnostics and for the treatment of inpatients and outpatients at the thyroid department. The Clinic for Nuclear Medicine became a teaching unit of the Medical Faculty and developed its own post-graduate programme – the first student enrolled in 1972. In the 1960s, radioisotope laboratories opened in the general hospitals of Slovenj Gradec and Celje, and in the 1970s also in Maribor, Izola and Šempeter pri Novi Gorici. Nowadays, nuclear medicine units are modernly equipped and the staff is trained in morphological, functional and laboratory diagnostics in clinical medicine. They also work on the treatment of cancer, increased thyroid function and other diseases

    The combination of positron emission tomography (PET) and computed tomography (CT) in a single scanner (PET/CT) allows anatomic and metabolic images to be fused and correlated with a high degree of accuracy; this represents a very important landmark in the history of medicine and especially in the area of diagnostic imaging. Nevertheless, the implementation, startup, and operation of a PET/CT scanner presents particularly interesting challenges, because it involves the integration of two well-established and consolidated techniques (CT and PET, which provide complementary information) that have traditionally been carried out in the context of two different specialties (radiology and nuclear medicine). The rapid diffusion of this new integrated technology raises a series of questions related to the optimal protocols for image acquisition, the supervision of the examinations, image interpretation, and reporting, as well as questions related to the legal competence and responsibility of the specialists involved in a PET/CT study. The objective of this article is to approach these aspects from a constructive perspective and to stimulate the dialog between the specialties of radiology and nuclear medicine, with the aim of maximizing the diagnostic potential of PET/CT and thus of providing better care for patients.

    Teresinska, Anna; Birkenfeld, Bozena; Krolicki, Leszek; Dziuk, Miroslaw

    2014-01-01

    In Poland, nuclear medicine (NM) has been an independent specialty since 1988. At the end of 2013, the syllabus for postgraduate specialization in NM has been modified to be in close accordance with the syllabus approved by the European Union of Medical Specialists and is expected to be enforced before the end of 2014. The National Consultant in Nuclear Medicine is responsible for the specialization program in NM. The Medical Center of Postgraduate Training is the administrative body which accepts the specialization programs, supervises the training, organizes the examinations, and awards the specialist title. Specialization in NM for physicians lasts for five years. It consists of 36 months of training in a native nuclear medicine department, 12 months of internship in radiology, 3 months in cardiology, 3 months in endocrinology, 3 months in oncology, and 3 months in two other departments of NM. If a NM trainee is a specialist of a clinical discipline and/or is after a long residency in NM departments, the specialization in NM can be shortened to three years. During the training, there are obligatory courses to be attended which include the elements of anatomy imaging in USG, CT, and MR. Currently, there are about 170 active NM specialists working for 38.5 million inhabitants in Poland. For other professionals working in NM departments, it is possible to get the title of a medical physics specialist after completing 3.5 years of training (for those with a master's in physics, technical physics or biomedical engineering) or the title of a radiopharmacy specialist after completing 3 years of training (for those with a master's in chemistry or biology). At present, the specialization program in NM for nurses is being developed by the Medical Centre of Postgraduate Education.

  8. Limits of Tumor Detectability in Nuclear Medicine and PET

    Full Text Available Objective: Nuclear medicine is becoming increasingly important in the early detection of malignancy. The advantage of nuclear medicine over other imaging modalities is the high sensitivity of the gamma camera. Nuclear medicine counting equipment has the capability of detecting levels of radioactivity which exceed background levels by as little as 2.4 to 1. This translates to only a few hundred counts per minute on a regular gamma camera or as few as 3 counts per minute when using coincidence detection on a positron emission tomography (PET camera. Material and Methods: We have experimentally measured the limits of detectability using a set of hollow spheres in a Jaszczak phantom at various tumor-to-background ratios. Imaging modalities for this work were (1 planar, (2 SPECT, (3 PET, and (4 planar camera with coincidence detection capability (MCD. Results: When there is no background (infinite contrast activity present, the detectability of tumors is similar for PET and planar imaging. With the presence of the background activity , PET can detect objects in an order of magnitude smaller in size than that can be seen by conventional planar imaging especially in the typical clinical low (3:1 T/B ratios. The detection capability of the MCD camera lies between a conventional nuclear medicine (planar / SPECT scans and the detection capability of a dedicated PET scanner Conclusion: Among nuclear medicine’s armamentarium, PET is the closest modality to CT or MR imaging in terms of limits of detection. Modern clinical PET scanners have a resolution limit of 4 mm, corresponding to the detection of tumors with a volume of 0.2 ml (7 mm diameter in 5:1 T/B ratio. It is also possible to obtain better resolution limits with dedicated brain and animal scanners. The future holds promise in development of new detector materials, improved camera design, and new reconstruction algorithms which will improve sensitivity, resolution, contrast, and thereby further

    Diagnostic nuclear medicine's recent history is characterized both by significant change and by growing participation in efforts to quantify the impact of nuclear medicine procedures on clinical judgment and patient management, as well as to develop methods for studying the efficacy of diagnostic procedures in general. The replacement of many nuclear medicine procedures that at one time were considered essential standards of clinical care by newer, more efficient and effective modalities has been complimented by the continued development of increasingly sophisticated applications of scintigraphic tracer methods

    Full text: Nuclear medicine (NM) imaging technology, alone and in combination with other imaging modalities, provides clinically significant and useful information in the staging and treatment of the oncological diseases. The main objective of our study was to find out and present the situation vis-a-vis nuclear medicine facilities in the Central European country that soon becomes the new member of EU. For the purposes statistical data of WHO, Slovak Republic (SR) and nuclear medicine department (NMD) were evaluated for the period 1995-2001. Comparison with Czech Republic (CR) was done because of almost similar occurrence of the malignant diseases in these two republics that were a one country till separation in 1993. First nuclear medicine department in Czechoslovakia was established about 55 years ago. Comparing to CR the expenditures on health care per capita in SR is only 67% of CR. The number of gamma cameras, physicians and number of investigations are far from good standard of CR. The number NM departments are significantly low and growth of only 29% compared to CR is alarming. The one main reason is inadequate financial support to the health care and high debts of hospitals running nuclear medicine facilities. Providing radiology departments with new CT and MRI scanners is another reason of less nuclear medicine facilities. During the last five years, though the number of gamma cameras increased by 10%, but the number of investigations did not rise accordingly. Because of bad management of health care services in Slovakia, the latest facilities availability is greatly delayed. However, the exception is the installation of a new PET scanner in 2001. Of late, sentinel lymph node detection was started only with the help of IAEA. Data shows that most of the nuclear medicine centers are around the state capital. It is imperative to have sufficient diagnostic and therapeutic facilities in each region so as to make these available to patients living away from the

    Following the AAPM Task Group Report No. 108, the NCRP Report No. 147 recommendations and the Cuban's local regulations for nuclear medicine practice were carried out the safety planning and design of a new PET/CT facility for the Nuclear Medicine Department of 'Hermanos Ameijeiras' Hospital. It should be installed in the top floor of the NM building (3th floor), occupied by offices, classrooms and ancillaries areas, meanwhile in the second floor is working the conventional nuclear medicine department. The radiation doses were evaluated in areas of the second, third and quarter floor taking into account the pet isotope, the workload, the occupancy factors of each place, the use factors of different sources and the dose reduction factors, warranty the accomplish of the Cuban dose restrictions associated to the nuclear medicine practice. In each point of calculation was considered the contribution from each source to the total dose, as well as the contribution of the CT in the adjacent room to the imaging room. For the proper facility design was considered the transmission factors of the existing barriers, and calculated the new ones to be added between each source and the estimation point, keeping in mind the space limitations. The PET/CT design plan meet all the needs, the development of the project is consistent with the mission of the facility and the radiation protection regulations of nuclear medicine. (Author)

    Except for dedicated devices for mobile nuclear cardiology for instance, the market is set on variable angulation dual heads cameras. These cameras are suited for all general applications and their cost effectiveness is optimized. Now, all major companies have such a camera in their of products. But, the big question in nuclear medicine is about the future of coincidence imaging for the monitoring of treatments in oncology. Many companies are focused on WIP assessments to find out the right crustal thickness to perform both high energy FDG procedures and low energy Tc procedures, with the same SPECT camera. The classic thickness is 3/8''. Assessments are made with 1/2'', 5/8'' or 3/4'' crystals. If FDG procedures proved to be of great interest in oncology, it may lead to the design of a dedicated SPECT camera with a 1'' crustal. Due to the short half of FDG, it may be the dawning of slip ring technology. (e.g. Varicam from Elscint). The three small heads camera market seems to be depressed. Will the new three large heads camera unveiled by Picker, reverse that trend? The last important topic in nuclear medicine is the emergence of new flat digital detectors to get rid of the old bulky ones. Digirad is the first company to manufacture a commercial product based on that technology. Bichron, Siemens and General Electric are working on that development, too. But that technology is very expensive and the market for digital detection in nuclear medicine is not as large as the market in digital detection in radiology. (author)

    2010-01-01

    In this review a list of commercially available 99m Tc-labeled radiopharmaceuticals was presented, and the significance to use them clinically was described in the face of this difficult situation due to the 99m Tc shortage. The supply history and the chronological change in the sales of 99 Mo/ 99m Tc generators in Japan were also described. I emphasize the importance of a nationwide spread of dedicated single photon emission computed tomography (SPECT)/CT equipments, which provide not only a simultaneous acquisition of dual tracers, but also information on both function and morphology. The present issues to address this difficult situation were discussed, referring to the summary of the Organization for Economic Co-operation and Development (OECD)/the Nuclear Energy Agency (NEA) workshop held in Paris and the press conference at the 56 th Society of Nuclear Medicine (SNM) annual meeting held in Toronto. The results of a questionnaire survey conducted in Saitama prefecture suggested the procedures, such as a domestic self-supply of 99 Mo, to resolve the issues related to the shortage. In addition, the ongoing Japan Materials Testing Reactor (JMTR) project regarding self-supply of 99 Mo was described. Based on a reliable supply of 99m Tc, the following suggestions to develop nuclear medicine were presented from the viewpoint of a nuclear medicine specialist; development of a brand-new SPECT/CT equipment using semi-conductor, clinical application of new tracers, and reassessment of the existing SPECT studies.

    Nuclear medicine operates with open radioactive substances in diagnostics and therapeutics. Diagnostic methods (as scintiscanning, SPECT, PET/CT) use so called radioactive tracer isotopes, their chemical exchange with stable isotopes is bound to metabolic processes. Beta or alpha emitting substances are used for therapeutic purposes. The 3D activity distribution is calculated using libraries and weighting factors recommended by ICRP based on phantom measurements. The contribution summarizes possible exposures of the medical personnel and radiation hygienic measures for personnel and patients' relatives. Further issues are the recommended threshold value measurements and the radioactive waste disposal.

  1. Nuclear medicine applications: Summary of Panel 4

    Wolf, A.P.

    1988-01-01

    Nuclear medicine is currently facing a desperate shortage of organic and inorganic chemists and nuclear pharmacists who also have advanced training in nuclear and radiochemistry. Ironically, this shortfall is occurring in the face of rapid growth and technological advances which have made the practice of nuclear medicine an integral part of the modern health care system. This shortage threatens to limit the availability of radiopharmaceuticals required in routine hospital procedures and to impede the development of new diagnostic and therapeutic agents. To redress this need and prevent a similar shortfall in the future, this panel recommends immediate action and a long-term commitment to the following: educating the public on the benefits of nuclear medicine; informing undergraduate and graduate chemistry students about career opportunities in nuclear medicine; offering upper level courses in nuclear and radiochemistry (including laboratory) in universities; establishing training centers and fellowships at the postgraduate level for specialized education in the aspects of nuclear and radiochemistry required by the nuclear medicine profession. 1 tab

    To the Editor: Referring to a recent special report about the cost analysis of twenty-nine nuclear medicine procedures, I would like to clarify some basic aspects for determining costs of nuclear medicine procedure with various costing methodologies. Activity Based Costing (ABC) method, is a new approach in imaging services costing that can provide the most accurate cost data, but is difficult to perform in nuclear medicine diagnostic procedures. That is because ABC requires determining and analyzing all direct and indirect costs of each procedure, according all its activities. Traditional costing methods, like those for estimating incomes and expenses per procedure or fixed and variable costs per procedure, which are widely used in break-even point analysis and the method of ratio-of-costs-to-charges per procedure may be easily performed in nuclear medicine departments, to evaluate the variability and differences between costs and reimbursement - charges.

    Since China first applied isotopes to medical research in 1956, over 800 hospitals and research institutions with 4000 staff have taken up nuclear technology. So far, over 120 important biologically active materials have been measured by radioimmunoassay in China, and 44 types of RIA kit have been supplied commercially. More than 50,000 cases of hyperthyroidism have been treated satisfactorily with 131 I. Radionuclide imaging of practically all organs and systems of the human body has been performed, and adrenal imaging and nuclear cardiology have become routine clinical practice in several large hospitals. The thyroid iodine uptake test, renogram tracing and cardiac function studies with a cardiac probe are also commonly used in most Chinese hospitals. The active principles of more than 60 medicinal herbs have been labelled with isotopes in order to study the drug metabolism and mechanism of action. Through the use of labelled neurotransmitters or deoxyglucose, RIA, radioreceptor assay and autoradiography, Chinese researchers have made remarkable achievements in the study of the scientific basis of acupuncture analgesia. In 1980 the Chinese Society of Nuclear Medicine was founded, and since 1981 the Chinese Journal of Nuclear Medicine has been published. Although nuclear medicine in China has already made some progress, when compared with advanced countries, much progress is still to be made. It is hoped that international scientific exchange will be strengthened in the future. (author)

    Governmental involvement in the practice of medicine has increased sharply within the past few years. The impact on health care has, for the most part, been in terms of financial interactions between health care facilities and federally funded health services programs. One might say that this type of governmental involvement has indirect impact on the medical and/or technical decisions in the practice of nuclear medicine. In other areas, however, governmental policies and regulations have had a more direct and fundamental impact on nuclear medicine than on any other medical specialty. Without an understanding and acceptance of this situation, the practice of nuclear medicine can be very frustrating. This chapter is thus written in the hope that potential frustration can be reduced or eliminated

    The aims of this study are to assess external radiation exposed doses of body and hands of nuclear medicine workers who handle radiation sources, and to measure radiation exposed doses of the hands induced by a whole body bone scan with high frequency and handling a radioactive sources like 99m Tc-HDP and 18 F-FDG in the PET/CT examination. Skillful workers, who directly dispense and inject from radiation sources, were asked to wear a TLD on the chest and ring finger. Then, radiation exposed dose and duration exposed from daily radiation sources for each section were measured by using a pocket dosimeter for the accumulated external doses and the absorbed dose to the hands. In the survey of four medical institutions in Incheon Metropolitan City, only one of four institutions has a radiation dosimeter for local area like hands. Most of institutions uses radiation shielding devices for the purpose of protecting the body trunk, not local area. Even some institutions were revealed not to use such a shielding device. The exposed doses on the hands of nuclear medicine workers who directly handles radioactive sources were approximately twice as much as those on the body. The radiation exposure level for each section of the whole body bone scan with high frequency and that of the PET/CT examination showed that radiation doses were revealed in decreasing order of synthesis of radioactive medicine and installation to a dispensing container, dispensing, administering and transferring. Furthermore, there were statistically significant differences of radiation exposure doses of the hands before and after wearing a syringe shielder in administration of a radioactive sources. In this study, although it did not reach the permissible effective dose for nuclear medicine, the occupational workers were exposed by relatively higher dose level than the non-occupational workers. Therefore, the workers, who closely exposed to radioactive sources should be in compliance with safety

    After a survey of the actual situation of nuclear medicine in Belgium, the evolution of nuclear medicine is studied with regard to quantitative aspects (tracerquantities, number of radioisotopic explorations, number of certified doctors) and qualitative aspects (use of short living isotopes emitting low energy radiation, introduction of in vitro tests). Taking these data into consideration, the exposure of nuclear medicine staff by external or internal radiation is evaluated. From this study it appears that the radiation exposure of the personnel of nuclear medicine departments remains low if proper manipulation methods and simple protective devices are used and if there is an efficient collaboration with an active health physics department or radiation control organism.

    The book presents a number of fundamental imaging principles in nuclear medicine. The fact that low radiation doses are sufficient for the study of normal and changed physiological functions of the body is an important advancement brought about by nuclear medicine. The possibility of quantitative investigations of organs and organ regions and of an assessment of their function as compared to normal values is a fascinating new diagnostic dimension. The possibility of comparing the findings with other pathological findings and of course control in the same patient lead to a dynamic continuity with many research possibilities not even recognized until now. The limits of nuclear scanning methods are presented by the imprecise structural information of the images. When scintiscans are compared with X-ray images or contrast angiography, the great difference in the imaging of anatomical details is clearly seen. But although the present pictures are not optimal, they are a great improvement on the pictures that were considered clinically valuable a few years ago. (orig./AJ) [de

    Radiopharmaceuticals are nowadays under the responsibility of the radio-pharmacist because of their medicinal product status. Radiopharmacy belongs to the hospital pharmacy department, nevertheless, interactions with nuclear medicine department are important: rooms are included or located near nuclear medicine departments in order to respect radiation protection rules, more over staff, a part of the material and some activities are shared between the two departments. Consequently, it seems essential to formalize links between the radiopharmacy and the nuclear medicine department, setting the goals to avoid conflicts and to ensure patients' security. Modalities chosen for this formalization will depend on the establishment's organization. (authors)

    Namibia is a country with 1,8 million inhabitants, of whom the majority has limited access to first world facilities. Nevertheless, medical services of high standard are offered. A Nuclear Medicine Department was established at Windhoek Central Hospital in 1982. A nuclear physician, two nuclear medicine radiographers and a nursing sister staff the department. Equipment includes a Siemens Orbiter and an Elscint Apex SPX Helix gamma camera. Radiopharmaceuticals are obtained from suppliers in South Africa. Investigations performed include musculoskeletal, liver, hepatobiliary, thyroid, renal studies, ventilation perfusion lung scans as well as the following Nuclear Cardiology studies: Gated blood pool scans, Tc-99m pyrophosphate hot spot scans, Tl-201 myocardial perfusion studies, Tc-99m MIBI myocardial perfusion studies and Tl-201 rest-redistribution studies. Problems experienced at the Windhoek Nuclear Medicine department include: Lack of funding and high cost of equipment and radiopharmaceuticals, lack of understanding of Nuclear Medicine by the hospital management and health administrators, and difficulties in procuring short-lived radiopharmaceuticals. Furthermore, the absence of company representatives and spare parts in Namibia leads to loss of time whenever equipment needs to be repaired. Working as the only nuclear medicine physician in a country also poses major problems. Careful management of resources and information drives have helped to sustain the Nuclear Medicine service despite economic problems in the country. Installation of a tele-link between the department in Windhoek Hospital and Tygerberg Hospital in South Africa has greatly assisted to overcome the problem of isolation and lack of back up from fellow specialists. The IAEA has equipped both departments with Hermes workstations (Nuclear Diagnostics) and a tele-link is maintained via modem. The current software provided with the Hermes system is ideally suited to processing of data such as gated

    This research was carry out due to the low presence of PET/CT projects in Venezuela in this moment, which consisted of the implementation and evaluation of a protocol for the acceptance and implementation of a hybrid tomograph PET/CT Discovery ST located in the nuclear medicine service at the Hospital de Clinicas Caracas. For this work, two references were used to provide a basic set of tests established and accepted by almost all manufacturers, such references are: NEMA 1994 PET and Spanish Protocol for Quality Control for Radiology CT. In general, we found that the smallest lesion in a functional image that this tomograph can resolve is {approx} 6mm. The spatial resolution of an anatomical image was resolved through 8 pl/cm. Likewise, this tomograph is able to produce a uniform anatomical and functional image, with very little noise and radiation scattered once the correction was done, referring to the test of co-registration accuracy of PET and CT shows that there is an excellent correspondence between the image of PET (functional) and the image of CT (anatomic), a basic parameter in a study of PET/CT.

    The China Society of Nuclear Medicine was established on 27 May 1980. Since then, nuclear medicine in clinical diagnosis and therapy has been developed rapidly in China. So far there are more than 4000 members of the Society, and more than 350 sets of SPECT and 12 sets of PET have been installed and are busily running in clinic nowadays and about 1 million patients with different types of diseases have obtained nuclear medicine imaging examinations per year. Concerning the nuclear medicine therapy, a lot of patients with many types of diseases obtained benefit from radioisotope therapy. Accordingly, several Policies and Regulations have been enacted by the Government for the radiological protection. Furthermore, a special book titled 'Standardization in Diagnostic and Therapeutic Nuclear Medicine' has been promulgated in June, 1997 by the Health Administration of People's Republic of China, and this book is distributed to almost every nuclear medicine physician and technician in China for their reference in routine nuclear medicine work or research. In this book three parts of the contents are covered: Policies and Regulations for the radiological protection, basic knowledge and clinical nuclear medicine applications. (author)

    Many nuclear medicine procedures, originally developed more than 20 years ago, are now performed with new radiopharmaceuticals or instruments; it is therefore apposite to reappraise what we are doing and why we are doing it. The clinical utility of nuclear medicine is discussed with reference, by way of example, to gated blood pools scans and myocardial perfusion imaging; the importance of the referred population for the outcome of studies is stressed. Attention is drawn to the likelohood that the detection of ischemia would be enhanced by the administration of nitroglycerin prior to rest thallium injection. Emphasis is also placed on the increasing acceptance of dual-tracer studies. The significance of expression of p-glycoprotein by some tumors for sestamibi imaging is discussed, and advances in respect of fluorodeoxyglucose imaging are reviewed. The final section covers issues relating to the development of new procedures, such as the value of nuclear medicine in the detection and characterization of tissue oxygen levels and the possible future role of nuclear medicine in the management of sleeping and eating disorders.

  9. Quality management audits in nuclear medicine practices

    International Nuclear Information System (INIS)

    2008-12-01

    An effective management system that integrates quality management (QM) is essential in modern nuclear medicine departments in Member States. The IAEA, in its Safety Standards Series, has published a Safety Requirement (GS-R-3) and a Safety Guide (GS-G-3.1) on management systems for all facilities. These publications address the application of an integrated management system approach that is applicable to nuclear medicine organizations as well. Quality management systems are maintained with the intent to continuously improve effectiveness and efficiency, enabling nuclear medicine to achieve the expectations of its quality policy, and to satisfy its customers. The IAEA has a long history of providing assistance in the field of nuclear medicine to its Member States. Regular quality audits and assessments are essential for modern nuclear medicine departments. More importantly, the entire QM and audit process has to be systematic, patient oriented and outcome based. The management of services should also take into account the diversity of nuclear medicine services around the world and multidisciplinary contributions. The latter include clinical, technical, radiopharmaceutical and medical physics procedures. Aspects of radiation safety and patient protection should also be integral to the process. Such an approach ensures consistency in providing safe, quality and superior services to patients. Increasingly standardized clinical protocol and evidence based medicine is used in nuclear medicine services, and some of these are recommended in numerous IAEA publications, for example, the Nuclear Medicine Resources Manual. Reference should also be made to other IAEA publications such as the IAEA Safety Standards Series, which include the regulations for the safe transport of nuclear material and on waste management as all of these have an impact on the provision of nuclear medicine services. The main objective of this publication is to introduce a routine of conducting an

    Full text:Ultrasonography is the modality of choice for demonstrating many cystic structures within the body. However nuclear medicine is often able to demonstrate functional disturbance where ultrasound and conventional radiography are unsuccessful. A case is presented in which a 16 day old male child presented to nuclear medicine with a right upper quadrant cyst found in ultrasound with exact location equivocal. Determining the location and nature of the cyst was essential to the treatment team for patient management. A hepatobiliary study was performed and evidence of a choledochal cyst was found. In partnership with ultrasound, nuclear medicine was able to identify a possibly malignant structure and consequently patient management was determined.

    This article traces the history of nuclear medicine in the country from the time the first radioisotope laboratory was set up by the Philippine General Hospital about 1955, to the not too satisfactory present facilities acquired by hospitals for diagnosis, treatment and investigation of diseases. It is in research, the investigation of disease that is nuclear medicine's most important area. The Philippine Atomic Energy Commission (PAEC) has pioneered in the conducting of courses in the medical uses of radioisotopes. The local training of nuclear manpower has been continued and updated and foreign fellowships are availed of through the cooperation of IAEA. Quite a number are already trained also in the allied fields that support the practice of nuclear medicine. However the brain drain has seriously affected the number of trained staff of medical units. Discussed and presented is the growth of the medical use of radioisotopes which are locally produced by PAEC. In order to benefit from the full advantage that nuclear medicine can do to a majority of Filipinos, the government should extend its financial support in acquiring such facilities to equip strategic hospitals in the country and support training programs. The Philippine has the expertise to start the expansion but only with adequate provision of funds will our capacity turn into reality. (RTD)

  13. Recent developments and future trends in nuclear medicine instrumentation

    2006-01-01

    Molecular imaging using high-resolution single-photon emission computed tomography (SPECT) and positron emission tomography (PET) has advanced elegantly and has steadily gained importance in the clinical and research arenas. Continuous efforts to integrate recent research findings for the design of different geometries and various detector technologies of SPECT and PET cameras have become the goal of both the academic community and nuclear medicine industry. As PET has recently become of more interest for clinical practice, several different design trends seem to have developed. Systems are being designed for ''low cost'' clinical applications, very high-resolution research applications (including small-animal imaging), and just about everywhere in-between. The development of dual-modality imaging systems has revolutionized the practice of nuclear medicine. The major advantage being that SPECT/PET data are intrinsically aligned to anatomical information from the X-ray computed tomography (CT), without the use of external markers or internal landmarks. On the other hand, combining PET with magnetic resonance imaging (MRI) technology is scientifically more challenging owing to the strong magnetic fields. Nevertheless, significant progress has been made resulting in the design of a prototype small animal PET scanner coupled to three multichannel photomultipliers via optical fibers, so that the PET detector can be operated within a conventional MR system. Thus, many different design paths are being pursued - which ones are likely to be the main stream of future commercial systems? It will be interesting, indeed, to see which technologies become the most popular in the future. This paper briefly summarizes state-of-the art developments in nuclear medicine instrumentation. Future prospects will also be discussed. (orig.)

  18. PET-CT for nuclear medicine diagnostics of multiple myeloma

    International Nuclear Information System (INIS)

    Dimitrakopoulou-Strauss, A.

    2014-01-01

    Functional or morphofunctional imaging modalities are used in myeloma patients for the diagnosis and therapy management within research protocols. Despite new staging criteria, which take into account the viability of a myeloma lesion, positron emission tomography (PET) is not used routinely. The impact of PET is therefore open. The role of PET and PET computed tomography (PET-CT) for the diagnosis and therapy management is discussed. The use of PET with 18F-fluorodeoxyglucose (FDG) allows the measurement of viable myeloma lesions and correlates with the stage of disease. A negative FDG examination correlates with a better prognosis. Furthermore, the number of focal lesions as well as the whole functional volume of myeloma lesions in FDG have a prognostic impact. Several studies have demonstrated the impact of FDG for the assessment of therapy monitoring and show that FDG is an earlier indicator for therapy response as compared to magnetic resonance imaging (MRI). The CT component of the new hybrid systems allows the assessment of osteolytic lesions in CT and their viability in FDG. The combination of PET with an MRT scanner allows the simultaneous measurement of bone marrow infiltration, focal lesions and their viability. The use of modern hybrid scanners, such as PET-CT and PET-MRT facilitates the simultaneous measurement of viable myeloma lesions, osteolytic lesions and bone marrow infiltration in the whole body; therefore, it is expected that these imaging modalities will play a greater role both in diagnosis and therapy management.

    The purpose was evaluating retrospectively the additional value of integrated positron emission tomography (PET) and computed tomography (CT) in the detection of pulmonary metastases in comparison with CT and PET alone. Fifty-six lung nodules, divided into three groups according their size, detected in 24 consecutive patients with a known primary tumor were retrospectively evaluated with integrated PET-CT, CT and PET. The nature of these nodules was determined by either histopathology or a follow-up of at least 6 months. The CT and PET images of the integrated PET-CT were evaluated separately by a radiologist and a nuclear medicine physician, the integrated PET-CT images were evaluated by a chest radiologist and nuclear medicine physician in consensus. The investigators were asked to search lung nodules and to determine whether these nodules were metastases or not. Sensitivity and accuracy for CT, PET and integrated PET-CT for characterization of all pulmonary nodules were, respectively: 100%, 90%, 100% and 57%, 55%, 55%. There was no significant difference in the characterization of pulmonary nodules between integrated PET-CT and CT alone (P=1.000) and PET alone (P=0.1306). An accurate evaluation is only possible for lesions larger than 1 cm. (orig.)

  7. Monte Carlo simulation in nuclear medicine

    Morel, Ch.

    2007-01-01

    The Monte Carlo method allows for simulating random processes by using series of pseudo-random numbers. It became an important tool in nuclear medicine to assist in the design of new medical imaging devices, optimise their use and analyse their data. Presently, the sophistication of the simulation tools allows the introduction of Monte Carlo predictions in data correction and image reconstruction processes. The availability to simulate time dependent processes opens up new horizons for Monte Carlo simulation in nuclear medicine. In a near future, these developments will allow to tackle simultaneously imaging and dosimetry issues and soon, case system Monte Carlo simulations may become part of the nuclear medicine diagnostic process. This paper describes some Monte Carlo method basics and the sampling methods that were developed for it. It gives a referenced list of different simulation software used in nuclear medicine and enumerates some of their present and prospective applications. (author)

This is true for the indication for the study and the interpretation of the results as well as the preparation, the image acquisition, the processing and the documentation. A continuous evaluation of all aspects is necessary to receive optimal, clinically relevant information. In addition it is important that the child keeps nuclear medicine in a good mind, especially when it has to come back for a control study. (orig.) [de

    The role of equine nuclear medicine in Australia has been previously described in this journal and more recently, Lyall et al. provided a general overview of demographics of veterinary nuclear medicine departments in Australia. Lyall et al. discuss the main clinical applications of nuclear medicine scintigraphy in companion animals; dogs and cats. The aim of this article is to discuss in brief the applications of commonly performed nuclear medicine procedures in humans with respect to veterinary applications. More detailed discussion will also be offered for investigation of pathologies unique to veterinary nuclear medicine or which are more common in animals than humans. Companion animals are living longer today due to advances in both veterinary and human medicine. The problem is, like humans, longevity brings higher incidence of old age morbidity. As a pet owner, one might be initially motivated to extend life expectancy which is followed by the realisation that one also demands quality of life for pets. Early detection through advanced diagnostic tools, like nuclear medicine scintigraphy, allows greater efficacy in veterinary disease. There are limited veterinary nuclear medicine facilities in Australia due to cost and demand. Not surprisingly then, the growth of veterinary nuclear medicine in Australia, and overseas, has been integrally coupled to evaluation of race horses. While these facilities are generally specifically designed for race horses, racing greyhounds, lame family horses and companion animals are being investigated more frequently. In the USA, the American College of Veterinary Radiology (ACVC) is very active clinically and in research. The ACVC journal, Journal of Veterinary Radiology and Ultrasound, is published quarterly and includes a Nuclear Medicine section. Within the ACVR is the Society of Veterinary Nuclear Medicine. Proliferation of veterinary nuclear medicine centres in the USA has been associated with insurance and lifestyle changes

    Nuclear medicine applications in Turkey started in the early 1950s, grew as an independent medical discipline and finally were recognized by the Ministry of Health in 1973. Later on, the professional organization of nuclear medicine physicians and other related professionals including radiopharmacists and technologists under the Turkish Society of Nuclear Medicine were established in 1975. Recently after completing more than a half century in Turkey, nuclear medicine has proved to be a strong and evolving medical field with more than 600 physicians serving for the changing needs of clinical practice throughout these years. This article describes past and present facts in this field and attempts to provide insights into the future which hopefully will be brighter than before.

    In the field of nuclear medicine imaging, breast imaging for cancer diagnosis is still mainly based on 2D imaging techniques. Three-dimensional tomographic imaging with whole-body PET or SPECT scanners, when used for imaging the breast, has performance limits in terms of spatial resolution and sensitivity, which can be overcome only with a dedicated instrumentation. However, only few hybrid imaging systems for PET/CT or SPECT/CT dedicated to the breast have been developed in the last decade, providing complementary functional and anatomical information on normal breast tissue and lesions. These systems are still under development and clinical trials on just few patients have been reported; no commercial dedicated breast PET/CT or SPECT/CT is available. This paper reviews combined dedicated breast PET/CT and SPECT/CT scanners described in the recent literature, with focus on their technological aspects.

    Although not frequently described in the podiatric literature, nuclear medicine imaging may be of great assistance to the clinical podiatrist. This report reviews in detail the use of modern nuclear medicine approaches to the diagnosis and management of the diabetic foot. Nuclear medicine techniques are helpful in evaluating possible osteomyelitis, in determining appropriate amputation levels, and in predicting response to conservative ulcer management. Specific indications for bone, gallium, and perfusion imaging are described

    Single-Photon Emission Computed Tomography-Computerized Tomography (SPECT-CT) is a new hybrid technique which offers new diagnostic capabilities in daily nuclear medicine practice. This technique not only allows to acquire merged anatomic and functional images in the same time, but also, it increases sensitivity and accuracy of SPECT thanks to attenuation and scattering corrections got from transmission data. Until now, SPECT-CT data have been mainly obtained in oncology and cardiology, but now, many authors use it in many scan studies and particularly for infectious diseases. In inflammatory bowel diseases, SPECT-CT seems to increase diagnostic performances and to modify management of many patients. In suspected vascular sepsis, SPECT-CT could increase sensitivity of white blood cell scintigraphy but also its specificity thanks to spatial resolution of CT. In osteo-articular sepsis, SPECT-CT has the advantage to distinguish osteomyelitis from soft tissue infection and to guide biopsies. Nevertheless, in the light of PET-CT works, SPECT-CT development will probably modify nuclear medicine practice and many studies have to be conducted to highlight consensual procedure guidelines.

    Carr, S.W.

    1998-01-01

    Full text: Nuclear medicine occupies an important niche in the spectrum of medical capability. Since its initial application on a routine basis over 30 years ago its importance has continued to grow. For example, it is expected that over 430,000 Australians will have a nuclear medicine procedure in 1998. Current procedures using nuclear medicine are mainly concerned with diagnosis of oncology, cardiology and neurology. The main radioisotope used in nuclear medicine is Tc 99m, which is produced by a 'so called' Mo-Tc 99m generator. Other isotopes which currently find routine use are Ga-67, Th-201 and I-131. The selective uptakes by particular organs or structures is facilitated by the use of 'cold kits' which after the chemistry of the radioisotope many of the recent advances have been concerned with increasing the selectivity for a particular organ structure. Several of these new agents show increased selectivity using antibody a peptide recognition units

  17. Analysis of data relative to the update of diagnostic reference levels in radiology and nuclear medicine. 2011-2012 review

    International Nuclear Information System (INIS)

    2014-01-01

    Applying the Order of 24 October 2011 on diagnostic reference levels, departments of radiology and nuclear medicine must send a sample of 'patient' dosimetric data to the IRSN each year. The results of the analysis of dosimetric data performed between the 1 January 2011 and the 31 December 2012 presented in this report should enable the authority to define the needs for updating regulations. Professional involvement in DRLs improved globally over the 2011-2012 period but is heterogeneous according to the imaging area considered. The participation of conventional radiology professionals is still low, with less than 30% against over 75% in CT and 85% in nuclear medicine. Data collection in pediatrics, considering all the fields of medical imaging, remains extremely limited. This shows almost no dose assessment for children by imaging departments, and has the effect of not allowing authorities to provide professionals with DRLs representative of pediatric practices. The analysis of radiology doses and nuclear medicine administered activities by IRSN shows an overall decrease of statistical indicators on which DRLs are indexed. These results lead to proposals for updating reference values for a large number of examinations. In addition to the analysis of data collected for examinations currently mentioned in regulatory texts, IRSN recommends to update DRLs in a more general way by changing the strategy for collecting and updating pediatric DRLs, by including interventional radiology - specialty in which the radiation protection presents a major challenge - by introducing a more ambitious indicator than the 75. percentile in conventional radiology and nuclear medicine - the 25. percentile statistical indicator, and by taking into account new technologies inducing additional exposures to the patient as CT-scan associated with the PET.

    PET means Positron Emission Tomography, it is a nuclear medicine technique in which radiopharmaceuticals labeled with positron emitters are used to obtain biochemical-metabolic images of the human body. The use of PET / CT contributes to obtain multimodal images that combine anatomical and metabolic information, allowing a more reliable diagnosis of a tumor or local or distant metastases in an organ or tissue. Other multimodal devices combine metabolic imaging with nuclear magnetic resonance. PET/CT is mainly used in Oncology (85-90%), Neurology, Cardiology, Inflammation and Infection although it is currently also used in different medical and surgical pathologies. The present work is aimed at showing what PET/CT is and how useful it is in Oncology. (author)

    Nuclear medicine in the Czech Republic is a full specialty with an exclusive practice. Since the training program was organized and structured in recent years, residents have had access to the specialty of nuclear medicine, starting with a two-year general internship (in internal medicine or radiology). At present, nuclear medicine services are provided in 45 departments. In total, 119 nuclear medicine specialists are currently registered. In order to obtain the title of Nuclear Medicine Specialist, five years of training are necessary; the first two years consist of a general internship in internal medicine or radiology. The remaining three years consist of training in the nuclear medicine specialty itself, but includes three months of practice in radiology. Twenty-one physicians are currently in nuclear medicine training and a mean of three specialists pass the final exam per year. The syllabus is very similar to that of the European Union of Medical Specialists (UEMS), namely concerning the minimum recommended numbers for diagnostic and therapeutic procedures. In principle, the Czech law requires continuous medical education for all practicing doctors. The Czech Medical Chamber has provided a continuing medical education (CME) system. Other national CMEs are not accepted in Czech Republic. (orig.)

    As the application of nuclear medicine to clinics became generalized and it held an important position, the Korean Society of Nuclear Medicine was founded in 1961, and today it has become known as one of the oldest nuclear medicine societies not only to Asian nations but also to other advanced countries all over the world. Now it has 100 or so regular members composed of students of each medicine filed unlike other medical societies. Only nuclear medicine research workers are eligible for its membership. The Korean Society of Nuclear Medicine holds its regular general meeting and symposium twice per annom respectively in addition to occasional group gatherings and provincial lectures on nuclear medicine. With an eye to exchanging information on symposium, research and know-how, KSNM issued its initial magazine in 1967. Every year two editions are published. Year after year the contents of treatises are getting elevated with researches on each field including the early study on morphology-greatly improved both in quality and quantity. Of late, a minute and fixed quantity of various matters by dynamical research and radioimmunoassay of every kind has become visibly active. In particular, since KSNM, unlike other local societies, keeps close and frequent contact with the nuclear medicine researchers of world-wide fame, monographs by eminent scholars of the world are carried in its magazine now internationally and well received in foreign countries. Now the magazine has been improved to such an extent that foreign authors quote its contents. KSNM invited many a foreign scholar with a view to exchanging the knowledge of nuclear medicine. Sponsored by nuclear energy institute, the nuclear medicine symposium held in Seoul in October of 1966 was a success with Dr. Wagner participating, a great scholar of world wide fame: It was the first international symposium ever held in Korea, and the Korea Japan symposium held in Seoul 1971 was attended by all distinguished nuclear

    The second congress of World Federation of Nuclear Medicine and Biology proved that nuclear medicine is returning to physiology. Around 1951, when motorized detector was introduced and when GM tube was replaced by scintillation crystal detector, physiologic nuclear medicine moved to anatomic nuclear medicine. Since 1970, when research on cardiology developed, nuclear medicine has been returning to physiology. Since 1963 Kuhl has been doing research on quantitative tomography which develops to emission computerized tomography emphasizing the physiological aspects of medicine. The recent contribution of nuclear medicine to medical science is the concept that human body is a unity of dynamic structure consisting of millions of cubes moving physio-chemically. (RUW)

    This study conducted to evaluate the radiation protection in nuclear medicine diagnostic procedures in four nuclear medicine departments in Sudan. The evaluated procedures followed in these departments were in accordance with the standards, International Recommendations and code of practice for radiation protection in nuclear medicine. The evolution included the optimum design for diagnostic nuclear medicine departments, dealing with radioactive sources, quality assurance and quality control, training and responsibilities for radiation worker taking into account economic factors in Sudan. Evaluation of radiation protection procedures in diagnostic investigations was carried out by taken direct measurements of dose rate and the contamination level in some areas where radiation sources, radiation workers and public are involved. Designated questionnaires covered thirteen areas of radiation protection based on inspection check list for nuclear medicine prepared by the International Atomic Energy Agency (IAEA) and American Association of Physicist in Medicine (AAPM) were used in the evaluation. This questionnaire has been Filled by Radiation Protection Officer (RPO), nuclear medicine technologist, nuclear medicine specialist in the nuclear medicine departments. Four hospitals, two governmental hospital and two private hospitals, have been assisted, the assessment shows that although the diagnostic nuclear medicine department in Sudan are not applying a fully safety and radiation protection procedures, but the level of radiation dose and the contamination level were found within acceptable limits. The private hospital D scored the higher level of protection (85.25%) while the governmental hospital C scored the lower level of protection (59.02%). Finally, this study stated some recommendations that if implemented could improve the level of radiation protection in nuclear medicine department. One of the most important recommendations is that a proper radiation protection

    thyroid cancer is about 3,7GBq (100 mCi). The maximum allowable radiation dose for the gen eral public, for both the carer of the patient and a family infant is 1 mSv. The maximum post I-131 therapy hospital discharge dose is 1 mSv at a 1.5 metre distance. An I-131 whole body scan is performed 3 days after I-131 therapy. The patient is followed-up in the nuclear medicine clinic after an additional week. I-131 WBS is performed annually for the first 2 years following radioiodine therapy to monitor the patient's progress. Normally, 185 MBq (5 mCi) scanning dose of I-131 is used. The patient is prepared for scanning by withdrawal of thyroxine suppression therapy 4 weeks prior to the scan. Serum thyroglobulin measurement is available in Uzbekistan at a cost of US$ 6 per sample. It is measured every 3 months routinely during the first 2 years post-radioiodine therapy. A pre-I-131 treatment level is also recorded four weeks after thyroidectomy. Antithyroglobulin antibody assay with appropriate dilutions is also available. Now, we are in negotiations with the IBA Company to introduce cyclotron and PET/CT in Uzbekistan. Thus, we will have the possibility of improving the diagnosis, to assess the response to therapy and monitoring of cancer patients. Nuclear Medicine in Uzbekistan has a bright future. (author)

    To provide an overview of recent research in fractal analysis of tissue perfusion imaging, using standard radiological and nuclear medicine imaging techniques including computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, positron emission tomography (PET) and single-photon emission computed tomography (SPECT) and to discuss implications for different fields of application. A systematic review of fractal analysis for tissue perfusion imaging was performed by searching the databases MEDLINE (via PubMed), EMBASE (via Ovid) and ISI Web of Science. Thirty-seven eligible studies were identified. Fractal analysis was performed on perfusion imaging of tumours, lung, myocardium, kidney, skeletal muscle and cerebral diseases. Clinically, different aspects of tumour perfusion and cerebral diseases were successfully evaluated including detection and classification. In physiological settings, it was shown that perfusion under different conditions and in various organs can be properly described using fractal analysis. Fractal analysis is a suitable method for quantifying heterogeneity from radiological and nuclear medicine perfusion images under a variety of conditions and in different organs. Further research is required to exploit physiologically proven fractal behaviour in the clinical setting. (orig.)

    2012-01-01

    The rapidly growing and somewhat complex area of nuclear medicine imaging receives only limited attention in broad-based medical dictionaries. This encyclopedic dictionary is intended to fill the gap. More than 400 entries of between one and three paragraphs are included, defining and carefully explaining terms in an appropriate degree of detail. The dictionary encompasses concepts used in planar, SPECT, and PET imaging protocols and covers both scanner operations and popular data analysis approaches. In spite of the mathematical complexities in the acquisition and analysis of images, the explanations given are kept simple and easy to understand; in addition, many helpful concrete examples are provided. Nuclear Medicine Imaging: An Encyclopedic Dictionary will be ideal for those who wish to obtain a rapid grasp of a concept beyond a definition of a few words but do not want to resort to a time-consuming search of the reference literature. The almost tutorial-like style accommodates the needs of students, nuclear medicine technologists, and varieties of other medical professionals who interface with specialists within nuclear medicine.

    In France, radiopharmaceutical prescription is often discussed depending to which juridical structure the nuclear medicine department is belonging. According to current regulation, this prescription is an obligation in a department linked to hospital with a pharmacy department inside. But situation remains unclear for independent nuclear medicine departments where physicians are not constrained to prescribe radiopharmaceuticals. However, as radiographers and nurses are only authorized to realize theirs acts in front of a medical prescription, one prescription must be realized. Nowadays, computerized prescription tools have been developed but only for radiopharmaceutical drugs and not for medical acts. In the aim to achieve a safer patient care, the prescription regulation may be applied whatever differences between nuclear medicines departments. (authors)

    2002-01-01

    The installation of a radiology information system (RIS) connected to a hospital information system (HIS) and a picture archiving and communications system (PACS) seems mandatory for a nuclear medicine department in order to guarantee a high patient throughput. With these systems a fast transmission of reports, images to the in- and out-patients' wards and private practitioners is realized. Therefore, since April 2000, at the department of nuclear medicine of the university of Wuerzburg a completely DICOM based PACS has been implemented in addition to the RIS. With this system a DICOM based workflow is realized throughout the department of nuclear medicine for reporting and archiving. The PACS is connected to six gamma-cameras, a PET scanner, a bone densitometry system and an ultrasound device. The volume of image data archived per month is 4 GByte. Patient demographics are provided to the modalities via DICOM-Worklist. With these PACS components a department specific archive purely based on DICOM can be realized. During the installation process problems occurred mainly because of the complex DICOM standard for nuclear medicine. Related to that is the problem that most of the software implementations still contain bugs or are not adapted to the needs of a nuclear medicine department (particularly for PET). A communication software for the distribution of nuclear medicine reports and images based on techniques used for the worldwide web is currently tested. (orig.) [de

    Digital computers were introduced to nuclear medicine research as an imaging modality in the mid-1960s. Widespread use of imaging computers (scintigraphic computers) was not seen in nuclear medicine clinics until the mid-1970s. For the user, the ability to acquire scintigraphic images into the computer for quantitative purposes, with accurate selection of regions of interest (ROIs), promised almost endless computational capabilities. Investigators quickly developed many new methods for quantitating the distribution patterns of radiopharmaceuticals within the body both spatially and temporally. The computer was used to acquire data on practically every organ that could be imaged by means of gamma cameras or rectilinear scanners. Methods of image processing borrowed from other disciplines were applied to scintigraphic computer images in an attempt to improve image quality. Image processing in nuclear medicine has evolved into a relatively extensive set of tasks that can be called on by the user to provide additional clinical information rather than to improve image quality. Digital computers are utilized in nuclear medicine departments for nonimaging applications also, Patient scheduling, archiving, radiopharmaceutical inventory, radioimmunoassay (RIA), and health physics are just a few of the areas in which the digital computer has proven helpful. The computer is useful in any area in which a large quantity of data needs to be accurately managed, especially over a long period of time

    Ten years ago specialists in Nuclear Medicine from the South of France formed an Association called ACOMEN. The objectives were to create a permanent exchange of ideas between members and a close collaboration with physicians. The group objectives have led to a combination of efforts on the behalf of each one to clarify our techniques for physicians having recourse to this speciality as well as the various categories of students passing through the Nuclear Medicine Departments. Different groups within the ACOMEN were assigned to specific subjects. Each group was in charge of building the framework of a certain topic, which was then illustrated by selected documents contributed by all members. A slide collection, complete with an explanatory booklet is the final result of this collaboration. Thus anyone concerned in any way, with nuclear medicine, is able to quickly become familiar with the techniques of the speciality, to be aware of its possibilities and its limitations and to update his hnowledge. One realizes that the first theme selected was not the easiest; pulmonary radionuclide explorations are, as everyone knows, variable and even personalized. However, the choice was deliberate. The difficulty should stimulate those responsible for the other themes as well as the people working with them. There is already a slide collection available to anyone who wishes to learn about the use of nuclear medicine in the diagnosis of respiratory diseases [fr

    Nuclear medicine comprises diagnosis and therapy of the diseases with radiopharmaceuticals. The ambition of all specialists in our country is their activity to reach European standards. In this connection, a Commission for external audit was formed to evaluate the quality of work in the centers of nuclear medicine. This Commission create a long-lasting programme based on the objective European criteria and the national standard of nuclear medicine, having in mind to increase quality of the work and the expert evaluation of activity in every center. The program comprises measures for quality control of instrumentation, radiopharmaceuticals, performed investigations, obtained results and the whole organization from the receiving of the isotopes to the results of the patients. The ambition is most of the centers to fulfill the requirements. As a conclusion it could be said that not only the quality of everyday nuclear medicine work is enough to increase the prestige of the specialty. It is also necessary we to have understanding expert and financial support from corresponding institutions, incl. Ministry of health for a delivery of a new, contemporary instrumentation with new possibilities. Thus it would be possible Bulgarian patients to reach the high technology apparatuses for an early functional diagnosis of the diseases and optimal treatment, which possibility have the patients from the developed countries.

    2008-01-01

    Nuclear medicine is an interdisciplinary department that deals with diagnosis and therapy using open sources. Therefore workers in nuclear medicine are in daily contact with ionizing radiation and thus it is essential to monitor a radiation load. Each work must therefore carry out monitoring of workers. It monitors compliance with the radiation limits set by law, allows an early detection of deviations from normal operation and to demonstrate whether the radiation protection at the workplace is optimized. This work describes the principles of monitoring of workers in nuclear medicine and monitoring methods for personal dosimetry. In the next section the author specifically deals with personal dosimetry at the Department of Nuclear Medicine St. Elizabeth Cancer Institute, Bratislava (KNM-Ba-OUSA). The main part of the work is to evaluate the results of a one-year monitoring of radiation workers KNM-Ba-OUSA. (author)

    Measurement of the hand dose during preparation and injection of radiopharmaceuticals is useful in the assessment of the extremity doses received by nuclear medicine personnel. Hand radiation doses to the occupational workers that handling 99m Tc-labeled compounds, 131 I for diagnostic in nuclear medicine were measured by thermoluminescence dosimetry. A convenient method is to use a TLD ring dosimeter for measuring doses of the diagnostic units of different nuclear medicine facilities . Their doses were reported in millisieverts that accumulated in 4 weeks. The radiation doses to the hands of nuclear medicine staff at the hospitals under study were measured. The maximum expected annual dose to the extremities appeared to be less than the annual limit (500 mSv/y) because all of these workers are on rotation and do not constantly handle radioactivity throughout the year

    Ultrasound and nuclear medicine are similar in that they both have been developed for clinical use in the past decade. Unlike X-ray techniques the success or failure of ultrasound and nuclear medicine depend more upon both the operator and the method of display. Since both ultrasound and nuclear medicine use relatively complicated methods of gathering and displaying information some of the lessons learnt during the development of nuclear medicine can be equally applied to ultrasound techniques.

    Public Health Authority of the Slovak Republic, Bratislava The exposure of the population to ionizing radiation is rising rapidly, nearly exclusively due to increasing medical use of radiation, including diagnostic methods of nuclear medicine. In 2012 Public health authority of the Slovak republic (PHA SR) performed a survey about the population exposure from nuclear medicine procedures. The primary objectives of this survey were to assess the frequency of different nuclear medicine procedures, determine the average activities administered by nuclear medicine procedures and compare them with the national diagnostic reference levels and determine the annual collective effective dose to the Slovak population from nuclear medicine. The effective dose calculation was based on the methodology of the ICRP32, ICRP80 and ICRP106. In Slovak republic are 11 nuclear medicine departments. The collected data of activities administered by different procedures correspond to 100 % of nuclear medicine departments. The total number of procedures included in the study was 36 250. The most commonly performed procedure was bone scintigraphy (35.9%), followed by lung perfusion and ventilation scintigraphy (17.0%), static and dynamic renal scintigraphy (13.0%), whole-body positron emission tomography of tumors with PET radiopharmaceuticals (11.6%), myocardial perfusion (8.8%), thyroid scintigraphy (6.2%), parathyroid scintigraphy (2.1%), scintigraphy of tumors (2.1%), scintigraphy of the liver and spleen (0.8%), brain perfusion (0.7%) and examination of the gastrointestinal system (0.3%).

    Saha, G.B.; Swanson, D.P.; Hladik, W.B. III

    1987-01-01

    Pharmacological interventions in nuclear medicine studies have been in practice for a long time. The triiodothyronine (T/sub 3/) suppression, Thyroid-stimulating hormone (TSH) stimulation, and perchlorate discharge tests are common examples of well-established diagnostic interventional studies. In recent years, pharmacologic and physiologic interventions in other nuclear medicine procedures have drawn considerable attention. The primary purpose of these interventions is to augment, complement or, more often, differentiate the information obtained from conventional nuclear medicine diagnostic studies. Pharmacologic interventions involve the administration of a specific drug before, during, or after the administration of radiopharmaceutical for a given study. The change in information due to intervention of the drug offers clues to differentiating various disease conditions. These changes can be brought about by physiologic interventions also, e.g., exercise in radionuclide ventriculography. In the latter interventions, the physiologic function of an organ is enhanced or decreased by physical maneuvers, and the changes observed can be used to differentiate various disease conditions

    The contribution of pulmonary nuclear medicine was evaluated in 115 patients with interstitial pulmonary diseases (IPD). Ventilation study (V) with {sup 81m}Kr or {sup 133}Xe, distribution of compliance in thoraco-pulmonary system (C) by {sup 81m}Kr gas bolus inhalation method, perfusion study (Q) with {sup 99m}Tc-MAA, {sup 67}Ga scintigraphy and an assessment of pulmonary epithelial permeability with {sup 99m}Tc-DTPA aerosol were performed as nuclear medicine procedures. Pulmonary function test (%DLco, vital capacity, and functional residual capacity) and blood gas analysis were also examined. Abnormalities in V were larger than that in Q, which was high V/Q mismatch finding, in interstitial pneumonia. Correlation between V/Q mismatch and PaO{sub 2} was, therefore, not significant. %DLco was decreased in cases with larger V/Q mismatches. {sup 67}Ga accumulated in the early stage of interstitial pneumonia when CT or chest X-ray did not show any finding. %DLco was decreased in cases with strong accumulation of {sup 67}Ga. {sup 67}Ga might be useful to evaluate activity of the disease. Pulmonary epithelial permeability was assessed by {sup 99m}Tc-DTPA inhalation study. This permeability became accelerated in idiopathic interstitial fibrosis and sarcoidosis. Pulmonary epithelial permeability may be useful as an indicator for epithelial cell injury. (author).

    The use of nuclear techniques in medicine has, also in South Africa, increased enormously, especially as regards diagnosis and reseach. In 1983 in vivo tests with radioisotopes were carried out and also in vitro tests, mainly by radioimmunoassay. Therapy with open and sealed radioactive sources was concentrated mainly on cancer treatments. In 1983 NUCOR supported 83 research projects in the life sciences. Imaging of organs or tissues in the body with nuclear techniques has developed into the most important application of nuclear medicine, with the development of even more specific labelled compounds as the main objective. Radioimmunoassay is at an exciting watershed, now that labelled monoclonal antibodies with high specificity for early diagnosis (also in cancer) and even localised radiotherapy have become available. The establishment of the 200 MeV open-sector cyclotron by the National Accelerator Centre also for medical purposes will, in addition to the large-scale production of the protonrich isotopes, also make a substantial contribution to radiotherapy with nuclear particles such as neutrons, protons and helium-3

    Multi-modality imaging with SPECT-CT in orthopaedics combines the excellent sensitivity of scintigraphy with the morphological information of CT as a key for specific interpretation of findings in bone scans. The result is an imaging modality with the clear potential to prove of value even in a competitive setting dominated by MRI, and to significantly add to diagnostic imaging in orthopaedics. SPECT-CT is of great value in the diagnostic evaluation after fractures, and - in contrast to MRI - it is well suited for imaging in patients with osteosyntheses and metallic implants. In sports medicine, SPECT-CT allows for a sensitive and specific detection of osseous stress reactions before morphological changes become detectable by CT or MRI. In patients with osseous pain syndromes, actively evolving degenerative changes as a cause of pain can be identified and accurately localized. Further, particularly prospective diagnostic studies providing comparative data are needed to strengthen the position of nuclear imaging in orthopaedics and sports medicine and to help implementing SPECT/CT in diagnostic algorithms.

    Garcheva, M.; Demirev, A.

    2014-01-01

    The application of recently introduced hybrid nuclear medicine methods gains importance in a variety of clinical fields, mainly because of the unique combination between functional and anatomical data provided by those methods and their capability for a precise localization of pathological processes. Single photon emission computed tomography, combined with computed tomography (SPECT/CT) is one of those methods. Its role in nuclear cardiology is important, because it provides quick attenuation correction and calculates the calcium score. In nuclear endocrinology SPECT/CT participates in thyroid and parathyroid examinations, especially in cases, where there is a need for localization of ectopic parathyroid or thyroid tissue. In nuclear pulmonology, one of the best ways to attribute certain changes seen on the SPECT, to the zone of interest on the CT, is to study the fused images obtained from the SPECT/ CT scanner. In cases of suspected infection and inflammation, fused images are indispensable for accurate localization of the involved tissue (structure) and for discrimination between normal/abnormal uptake. Careful reading of the CT component (even low-dose) is related (in 10% of cases) to clinically important incidental findings: effusions, tumors, metastases or lymph node pathology. SPECT/CT increases the specificity of the examinations and improves significantly the localization of pathological processes. It provides additional information, shortens the diagnostic algorithm and influences the extent of surgical procedures. In many hybrid examinations the preferred CT component is a low-dose one, without considerable radiation exposure. The opportunity to combine nuclear medicine techniques and contrast CT images, aiming at better diagnosis needs further development. SPECT/CT provides important additional information and more accurate diagnostics in patients with benign diseases. (authors) Key words: SPECT/CT. BENIGN DISEASES

    1977-01-01

    Numerical description of medical and biologic phenomena is proliferating. Laboratory studies on patients now yield measurements of at least a dozen indices, each with its own normal limits. Within nuclear medicine, numerical analysis as well as numerical measurement and the use of computers are becoming more common. While the digital computer has proved to be a valuable tool for measurment and analysis of imaging and radioimmunoassay data, it has created more work in that users now ask for more detailed calculations and for indices that measure the reliability of quantified observations. The following material is presented with the intention of providing a straight-forward methodology to determine values for some useful parameters and to estimate the errors involved. The process used is that of asking relevant questions and then providing answers by illustrations. It is hoped that this will help the reader avoid an error of the third kind, that is, the error of statistical misrepresentation or inadvertent deception. This occurs most frequently in cases where the right answer is found to the wrong question. The purposes of this chapter are: (1) to provide some relevant statistical theory, using a terminology suitable for the nuclear medicine field; (2) to demonstrate the application of a number of statistical methods to the kinds of data commonly encountered in nuclear medicine; (3) to provide a framework to assist the experimenter in choosing the method and the questions most suitable for the experiment at hand; and (4) to present a simple approach for a quantitative quality control program for scintillation cameras and other radiation detectors

Despite all of these efforts, an appraisal of the true utility of computers in the day-to-day practice of nuclear medicine is yet to be achieved. Now that the technology of data storage and processing in nuclear medicine has reached a high degree of sophistication, as evidenced by many reports in the literature, the time has come to develop a perspective on the proper place of computers in nuclear medicine practice. The paper summarizes various uses of a dedicated computer (Nuclear Data Med II) at our two institutions and comments on its clinical utility. (author)

    2010-01-01

    The positron emission tomography in combination with CT in hybrid, cross-modality imaging systems (PET/CT) gains more and more importance as a part of the treatment-planning procedure in radiotherapy. Positron emission tomography (PET), as a integral part of nuclear medicine imaging and non-invasive imaging technique, offers the visualization and quantification of pre-selected tracer metabolism. In combination with the structural information from CT, this molecular imaging technique has great potential to support and improve the outcome of the treatment-planning procedure prior to radiotherapy. By the choice of the PET-Tracer, a variety of different metabolic processes can be visualized. First and foremost, this is the glucose metabolism of a tissue as well as for instance hypoxia or cell proliferation. This paper comprises the system characteristics of hybrid PET/CT systems. Acquisition and processing protocols are described in general and modifications to cope with the special needs in radiooncology. This starts with the different position of the patient on a special table top, continues with the use of the same fixation material as used for positioning of the patient in radiooncology while simulation and irradiation and leads to special processing protocols that include the delineation of the volumes that are subject to treatment planning and irradiation (PTV, GTV, CTV, etc.). General CT acquisition and processing parameters as well as the use of contrast enhancement of the CT are described. The possible risks and pitfalls the investigator could face during the hybrid-imaging procedure are explained and listed. The interdisciplinary use of different imaging modalities implies a increase of the volume of data created. These data need to be stored and communicated fast, safe and correct. Therefore, the DICOM-Standard provides objects and classes for this purpose (DICOM RT). Furthermore, the standard DICOM objects and classes for nuclear medicine (NM, PT) and

    The advent of nuclear medicine in the early 1940's came with the use of radioiodine in the study of thyroid physiology and eventual treatment of hyperthyroidism. Instrumentation to detect radionuclides introduced into the human body, and the production of various radiopharmaceuticals as tracers or as therapy agents provided the impetus for the rapid development of nuclear medicine as a distinct specialty. In the Philippines, nuclear medicine formally began in 1956 with the establishment of the Radioisotope Laboratory at the Philippine General Hospital. Acquisition of nuclear instrumentation by various institutions, training of medical staff and personnel, sourcing of radiopharmaceuticals proceeded thereafter

    Complementary alternative medicines (CAMs), including food supplements, are taken widely by patients, especially those with cancer. Others take CAMs hoping to improve fitness or prevent disease. Physicians (and patients) may not be aware of the potential side-effects and interactions of CAMs with conventional treatment. Likewise, their known physiological effects could interfere with radiopharmaceutical kinetics, producing abnormal treatment responses and diagnostic results. Nuclear medicine physicians are encouraged to question patients on their intake of CAMs when taking their history prior to radionuclide therapy or diagnosis. The potential effect of CAMs should be considered when unexpected therapeutic or diagnostic results are found. (orig.)

    Quality management systems are essential and should be maintained with the intent to continuously improve effectiveness and efficiency, enabling nuclear medicine to achieve the expectations of its quality policy, satisfy its customers and improve professionalism. The quality management (QM) audit methodology in nuclear medicine practice, introduced in this publication, is designed to be applied to a variety of economic circumstances. A key outcome is a culture of reviewing all processes of the clinical service for continuous improvement in nuclear medicine practice. Regular quality audits and assessments are vital for modern nuclear medicine services. More importantly, the entire QM and audit process has to be systematic, patient oriented and outcome based. The management of services should also take into account the diversity of nuclear medicine services around the world and multidisciplinary contributions. The latter include clinical, technical, radiopharmaceutical, medical physics and radiation safety procedures

    In this chapter are described methods of patient preparation that can favorably affect the outcome of nuclear medicine studies in specific situations. Some of these practices may be considered essential to the success of the nuclear medicine procedure, whereas others may be thought of simply as a means of obtaining more valid or reliable information. Regardless of relative importance, each of the preparatory methods discussed can contribute to the quality of the respective study and can serve as a means of maximizing the value of nuclear medicine procedures. The specific patient preparation techniques discussed in this chapter may not be readily applicable to every practice setting or situation. These or similar procedures can be used or modified as necessary. It is important, however, that when new protocols are developed, the rationale and theoretical basis of each technique be considered

    Radiation is really nothing more than the emission of energy through space, as well as through physical objects. Nuclear radiations are emitted due to decay of nuclei of radioactive materials and damage cells and the DNA inside them through its ionizing effect. That causes melanoma and other cancers. Nuclear radiation has a number of beneficial uses especially in medical field with low levels of radioactive compounds, better than X-rays. There are some 440 nuclear reactors worldwide, people around will be under the effect of radiation. In nuclear medicine (medical imaging) small amount of radioactive materials were used to diagnose and determine the severity of or treat a variety of disease, including many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders and other abnormalities within the body it is painless and cost-effective techniques and provides information about both structure and function. Nuclear medicine diagnostic procedures called Gamma camera, single photon emission computed tomography (SPECT) and positron emission tomography (PET) were discussed in this paper. (author)

    In this study we demonstrate our Radiology Department\\'s experience in utilizing low dose (half the normal dose) lung perfusion radionuclide scanning for pregnant patients as the initial investigation for suspected pulmonary embolism (PE). Secondly; we highlight the radiation dose reduction advantages of nuclear medicine imaging over multi-detector computed tomography in this group. We performed a retrospective study of 21 consecutive pregnant women who presented with suspected PE. These patients underwent either lung perfusion scanning or CT pulmonary angiography (CTPA), over a two-year period (May 2005 to July 2007). 19 patients of the cohort studied underwent low dose perfusion-only scintigraphy, with half the usual dose of radionuclide activity. All scans were considered of diagnostic quality. No patient in our study required a ventilation scan. No patient with a negative perfusion scan represented during the 3 month follow up period with PE. We conclude, nuclear medicine imaging is an effective initial investigation for pregnant patients with suspected PE. While scinitigraphy is associated with a greater fetal radiation dose than CTPA, it imparts a lower maternal dose and significantly lower dose to radiosensitive tissues such as breast.

  16. Nuclear medicine research: an evaluation of the ERDA program

    International Nuclear Information System (INIS)

    1976-08-01

    Legislation which established the Energy Research and Development Administration (ERDA) January 19, 1975, stipulated that this new agency should be responsible for all activities previously assigned to the Atomic Energy Commission (AEC) and not specifically assigned to other agencies. Such activities included the nuclear medicine research program of the AEC Division of Biomedical and Environmental Research (DBER). To determine whether continuation of this program under the broader ERDA mission of energy-related research was in fact appropriate, a special task force was appointed in January 1975 by Dr. James L. Liverman, the director of DBER. This task force, comprised of established scientists knowledgeable about issues related to nuclear medicine either currently or in the past, was charged specifically to assess the historical impact of the AEC/ERDA nuclear medicine program on the development of nuclear medicine, the current status of this program, and its future role within the structure of ERDA. The specific recommendations, in brief form, are as follows: the federal government should continue to support the medical application of nuclear technology; ERDA should retain primary responsibility for support and management of federal nuclear medicine research programs; and management and emphasis of the ERDA nuclear medicine program require modification in certain areas, which are set forth

    Neutrons produced by research reactors are being used in nuclear medicine and other medical applications in several ways. The High Flux Reactor (HFR) based in Petten (The Netherlands), owned by the European Commission, has been working increasingly in this field of health care for the European citizen. On the basis of this experience, a survey has been carried out on the main possibilities of neutrons used in nuclear medicine. The most important and most well known is the production of radioisotopes for diagnosis and therapy. Ten million patients receive nuclear medicine in Europe each year, with more than 8 million made with the products issued from research reactors. The survey of the market and the techniques (cyclotron, PET) shows that this market will continue to increase in the future. The direct use of reactors in medicine is actually made by the Boron Neutron capture Therapy (BNCT) for the treatment of glioblastoma, which kills about 15.000 people in Europe each year. For this promising technique, HFR is the most advanced for experimental possibilities and treatment studies.

    2002-01-01

    In any application involving the use of ionizing radiation in humans, risks and benefits must be properly evaluated and balanced. Radionuclides are used in nuclear medicine in a variety of diagnostic and therapeutic procedures. Recently, interest has grown in therapeutic agents for a number of applications in nuclear medicine, particularly in the treatment of hematologic and non-hematologic malignancies. This has heightened interest in the need for radiation dose calculations and challenged the scientific community to develop more patient-specific and relevant dose models. Consideration of radiation dose in such studies is central to efforts to maximize dose to tumor while sparing normal tissues. In many applications, a significant absorbed dose may be received by some radiosensitive organs, particularly the active marrow. This talk will review the methods and models used in internal dosimetry in nuclear medicine, and discuss some current trends and challenges in this field

The CT and MRI features of 16 consecutive Gynura segetum induced HSOS cases (12 men, 4 women) were analyzed. Eight patients had CT; three patients had MRI, and the remaining five patients had both CT and MRI examinations. Based on their clinical presentations and outcomes, the patients were classified into three categories: mild, moderate, and severe. The severity of the disease was also evaluated radiologically based on the abnormal hepatic patchy enhancement in post-contrast CT or MRI images. Ascites, patchy liver enhancement, and main right hepatic vein narrowing or occlusion were present in all 16 cases. Hepatomegaly and gallbladder wall thickening were present in 14 cases (87.5%, 14/16). Periportal high intensity on T2-weighted images was present in 6 cases (75%, 6/8). Normal liver parenchymal enhancement surrounding the main hepatic vein forming a clover-like sign was observed in 4 cases (25%, 4/16). The extent of patchy liver enhancement was statistically associated with clinical severity classification (kappa = 0.565). Ascites, patchy liver enhancement, and the main hepatic veins narrowing were the most frequent signs of herbal medicine induced HSOS. The grade of abnormal patchy liver enhancement was associated with the clinical severity.

    To describe the CT and MRI features of hepatic sinusoidal obstruction syndrome (HSOS) caused by herbal medicine Gynura segetum. The CT and MRI features of 16 consecutive Gynura segetum induced HSOS cases (12 men, 4 women) were analyzed. Eight patients had CT; three patients had MRI, and the remaining five patients had both CT and MRI examinations. Based on their clinical presentations and outcomes, the patients were classified into three categories: mild, moderate, and severe. The severity of the disease was also evaluated radiologically based on the abnormal hepatic patchy enhancement in post-contrast CT or MRI images. Ascites, patchy liver enhancement, and main right hepatic vein narrowing or occlusion were present in all 16 cases. Hepatomegaly and gallbladder wall thickening were present in 14 cases (87.5%, 14/16). Periportal high intensity on T2-weighted images was present in 6 cases (75%, 6/8). Normal liver parenchymal enhancement surrounding the main hepatic vein forming a clover-like sign was observed in 4 cases (25%, 4/16). The extent of patchy liver enhancement was statistically associated with clinical severity classification (kappa = 0.565). Ascites, patchy liver enhancement, and the main hepatic veins narrowing were the most frequent signs of herbal medicine induced HSOS. The grade of abnormal patchy liver enhancement was associated with the clinical severity.

  17. Radiochemistry and its application to nuclear medicine

    1990-01-01

    The role of the radiochemist in Nuclear Medicine has increased since the early 1960's. At that time the first medical 99 Mo/ 99m /Tc generator was developed at Brookhaven National Laboratory and the first hospital based cyclotron installed at Washington University. Radiochemists have been involved in both the development and application of generator and accelerator based radiopharmaceuticals. The development of oxygen-15, nitrogen 13, carbon-11 and fluorine-18 simple compound and synthetic precursors will be discussed. In recent years new high current accelerators have been proposed from Nuclear Medicine isotope production. Generator produced radiopharmaceuticals continue to play a major role in Nuclear Medicine. Problems in the development of targetry to produce parent nuclides as well as challenges in generator development will be described

    The growth is described of nuclear medicine departments and units in Czechoslovakia in the past 25 years of the existence of the Czechoslovak Society for Nuclear Medicine and Radiation Hygiene, the numbers of personnel and their qualifications. While only three nuclear medicine units were involved in the use of radioisotopes for diagnostic and therapeutic purposes in the 1950's, 29 specialized departments and 15 laboratories are now in existence with a staff of 299 medical doctors and other university graduates and 365 technicians and nurses. They operate all possible instruments, from simple detector devices via gamma cameras to computer tomographs. Briefly, the involvement of the Society is described in coordinated research programs, both with institutions in the country and with the other CMEA countries and IAEA.

  15. The Present Status of Nuclear Medicine in Korea

    Lee, Mun Ho

    1968-01-01

    It is my privilege to give you a brief history on the status of nuclear medicine in Korea. There is nothing much to mention, as the history of the peaceful use of atomic energy is rather short and the RI facilities are limited in the number. It is my sincere hope, however, that you may understand what steps nuclear medicine in the developing countries did take and how it has been developed, seeing the present status of nuclear medicine in Korea, as one of the models. In our country, the peaceful use of atomic energy was actualized since the Law of Atomic Energy had been enacted in March 1959, and the Office of Atomic Energy and the Atomic Energy Research Institute had been established. The Korea Society of Nuclear Medicine was organized in 1961, which i think is one of the older in the Far East area. The Society now held about 170 members and the annual meetings in addition to the quarterly meeting have been held. The 6th general scientific meeting for 1967 is scheduled to be held in 25 November. The society publishes the Korean Journal of Nuclear Medicine twice a year, and the second issue appeared Oct. 1967. The instruments used in nuclear medicine are mostly expensive, therefore, the hospitals equipped with such instruments are inevitably limited in number and the after-service or repair of such instruments are technically not easy. Some of these difficulties, i hope, shall be overcome in the near future.

  16. Exposure from diagnostic nuclear medicine procedures

    Iacob, O.; Diaconescu, C.; Isac, R.

    2002-01-01

    According to our last national study on population exposures from natural and artificial sources of ionizing radiation, 16% of overall annual collective effective dose represent the contribution of diagnostic medical exposures. Of this value, 92% is due to diagnostic X-ray examinations and only 8% arise from diagnostic nuclear medicine procedures. This small contribution to collective dose is mainly the result of their lower frequency compared to that of the X-ray examinations, doses delivered to patients being, on average, ten times higher. The purpose of this review was to reassess the population exposure from in vivo diagnostic nuclear medicine procedures and to evaluate the temporal trends of diagnostic usage of radiopharmaceuticals in Romania. The current survey is the third one conducted in the last decade. As in the previous ones (1990 and 1995), the contribution of the Radiation Hygiene Laboratories Network of the Ministry of Health and Family in collecting data from nuclear medicine departments in hospitals was very important

    Full text: Nuclear medicine in South Africa has been a full specialty on its own since 1987. It is practiced in almost all teaching hospitals and within the private sector in larger cities. Most of the routine radiopharmaceuticals are domestically manufactured and the main isotope can be obtained from locally produced technetium generators. All the radionuclide imaging devices used in the country are imported. The main vendors are GE, Siemens and Phillips. The majority of radionuclide imaging comprises work from nuclear cardiology and nuclear oncology. Almost all the routine clinical nuclear medicine procedures are performed and some in vitro work is also done, however. Principal therapeutic agents used in the country include radioactive iodine, radioactive iodine MIBG and yttrium. The country still lacks experience in receptors imaging and radioimmunology work and no PET scanner has been purchased yet. The academic institutions are active with participation in national and international congresses and also with publications. Although much remains to be done, the future of nuclear medicine in South Africa does not appear gloomy. (author)

    Nuclear medicine examinations in children require a maximum in quality. This is true for the preparation of the child and parents, the imaging procedure, processing and documentation. It is necessary that quality control through all steps is performed regularly. The aim must be that the children receive a minimum radiation dose, while there needs to be a high quality in imaging and clinical information from the study. Furthermore the child should not be too much psychologically affected by the nuclear medicine examination. (orig.) [de

  10. Involvement of WHO in the improvement of nuclear medicine in developing countries

    1986-01-01

    The World Health Organization's programme on nuclear medicine deals with the organization of nuclear medicine services, the training of personnel, the efficacy and efficiency of nuclear medicine, and quality assurance in nuclear medicine, instrumentation and radiopharmaceuticals. An analysis of the present situation in diagnostic imaging shows that new techniques and especially ultrasonography (US) may successfully compete with nuclear medicine. WHO is therefore concerned to stimulate objective evaluations of the appropriate role of each diagnostic imaging technology and to make relevant recommendations. In diagnostic nuclear medicine, the following main objectives are included in the WHO strategy: to restrict diagnostic nuclear medicine to those diseases where it cannot be substituted by other less costly and complicated methods; to decrease the cost of diagnostic procedures; and to prevent radiation hazard to patients, personnel and the public from the expanded use of radiopharmaceuticals. In the developing world this strategy may be carried out in two stages: (1) implementation of US in diagnostic services and the initiation of a comparative study of the diagnostic value of US and nuclear medicine imaging techniques in common diseases; (2) working out appropriate recommendations on a rational approach in imaging diagnostics and substitution of nuclear medicine by US in appropriate areas. The Intercomparison Study on Quality Performance of Nuclear Medicine Imaging Devices, established by WHO jointly with the International Atomic Energy Agency, and the organization of training workshops are examples of a successful approach to quality improvement in nuclear medicine in developing countries.

    For over 50 years the Office of Biological and Environmental Research (BER) of the United States Department of Energy (DOE) has been investing to advance environmental and biomedical knowledge connected to energy. The BER Medical Sciences program fosters research to develop beneficial applications of nuclear technologies for medical diagnosis and treatment of many diseases. Today, nuclear medicine helps millions of patients annually in the United States. Nearly every nuclear medicine scan or test used today was made possible by past BER-funded research on radiotracers, radiation detection devices, gamma cameras, PET and SPECT scanners, and computer science. The heart of biological research within BER has always been the pursuit of improved human health. The nuclear medicine of tomorrow will depend greatly on today's BER-supported research, particularly in the discovery of radiopharmaceuticals that seek specific molecular and genetic targets, the design of advanced scanners needed to create meaningful images with these future radiotracers, and the promise of new radiopharmaceutical treatments for cancers and genetic diseases.

    The role of nuclear medicine in disease management in a developing nation is as impactful as it is in other regions of the world. However, in the developing world, the practice of nuclear medicine is faced with a myriad of challenges, which can be easily avoided. In this review, we examine the many avoidable challenges to the practice of nuclear medicine in a developing nation. The review is largely based on personal experiences of the authors who are the pioneers and current practitioners of nuclear medicine in a typical developing nation. If the challenges examined in this review are avoided, the practice of nuclear medicine in such a nation will be more effective and practitioners will be more efficient in service delivery. Hence, the huge benefits of nuclear medicine will be made available to patients in such a developing nation

    This paper specifies the main elements of the radiation protection programma (RPP) that should be estabished for each practice, which involves radiation exposure. Practices of nuclear medicine have been considered as an example, since among the 245 installations which are conducting different practices with radiation sources in the Kingdom of Saudi Arabia, there are 78 installations dealing with nuclear medicine practices. Reviewing the RPP in these nuclear medicine installations, it may be easily concluded that the RPPs for the majority of these installations do not respond to the requirements of the regulatory body of the Kingdom, which is King Abdulaziz City for Science and Technology (KACST). This may be attributed to a set of different reasons, such as shortage in understanding the main elements of the RPP as well as in applying methodologies

    Nuclear medicine is high-tech medicine. Nevertheless, it is essential for addressing important health problems of people living in developing countries also. Not only is it sometimes expensive to start with, it also involves a lot of technical know-how, requiring transfer of technology from developed to the developing countries. The rapid development of nuclear medicine, of sophisticated instrumentation and radiopharmaceuticals has resulted in an enormous increase in costs and in the need for maintaining quality. These constitute a challenge and a venture when promoting nuclear medicine globally and particularly in developing countries. No other international organization except IAEA has any specific mandate for application of nuclear energy in the area of human health. WHO has no specific programin nuclear medicine, hence the importance of IAEA's involvement. The IAEA has, ever since its inception, given high priority to enhancing the awareness and capabilities of developing member states to employ nuclear technology for health care and medical research. Much of the Agency promoted research in nuclear medicine is delivered through the so called co-ordinated research projects (CRPs). The CRPs are normally organised as multi-center, prospective studies so that large volume of scientific data could be generated in a short period of 18-24 months. The research is normally done within an operational frame work, established and co-ordinated by the IAEA. The reason for this is that the results can be compared despite site or country specific differences. The methods and materials used for such studies usually conform to a predetermined standard. The protocols for various investigations, criteria for patient selection, mode of arriving at a final diagnosis and analysis of data from these multi-center studies are normally agreed upon by the Chief Scientific Investigators from each participating institution and the IAEA prior to the start of the actual work programme.

    Fundamental knowledge of radiologic anatomy and physiology is critical for medical physicists. Many physicists are exposed to this topic only in graduate school, and knowledge is seldom formally evaluated or assessed after Part I of the ABR exam. Successful interactions with clinicians, including surgeons, radiologists, and oncologists requires that the medical physicist possess this knowledge. This course presents a review of radiologic anatomy and physiology as it applies to projection radiography, fluoroscopy, CT, MRI, U/S, and nuclear medicine. We will review structural anatomy, manipulation of tissue contrast, the marriage between anatomy and physiology, and explore how medical imaging exploits normal and pathological processes in the body to generate contrast. Learning Objectives: Review radiologic anatomy. Examine techniques to manipulate tissue contrast in radiology. Integrate anatomy and physiology in molecular imaging.

    This book on nuclear medicine in bone diagnostics and other complementary imaging methods is composed out of the 51 presentations of the 2nd Tuebinger bone symposium held on the 11th and 12th January 1985; it gives an overview of newer methods of nuclear medicine and other imaging methods such as magnetic-resonance tomography and sonography. While the 1st Tuebinger Symposium in January 1981 dealt with the clinical application of classical bone scintigraphy and the possibilities of the results of differential diagnosis, the present book is concerned with indications, alternative radiopharmaceuticals for skeleton scintigraphy and other techniques. The intention is to give a survey of the developments made over the last few years. (orig./MG) [de

    2016-01-01

    The number of counts used in nuclear medicine imaging techniques, only provides physical information about the desintegration of the nucleus present in the the radiotracer molecules that were uptaken in a particular anatomical region, but that information is not a real metabolic information. For this reason a mathematical method was used to find a correlation between number of counts and "1"8F-FDG mass concentration. This correlation allows a better interpretation of the results obtained in the study of diffusive processes in an agar phantom, and based on it, an image from the PETCETIX DICOM sample image set from OsiriX-viewer software was processed. PET-CT gradient magnitude and Laplacian images could show direct information on diffusive processes for radiopharmaceuticals that enter into the cells by simple diffusion. In the case of the radiopharmaceutical "1"8F-FDG is necessary to include pharmacokinetic models, to make a correct interpretation of the gradient magnitude and Laplacian of counts images.

    The number of counts used in nuclear medicine imaging techniques, only provides physical information about the desintegration of the nucleus present in the the radiotracer molecules that were uptaken in a particular anatomical region, but that information is not a real metabolic information. For this reason a mathematical method was used to find a correlation between number of counts and {sup 18}F-FDG mass concentration. This correlation allows a better interpretation of the results obtained in the study of diffusive processes in an agar phantom, and based on it, an image from the PETCETIX DICOM sample image set from OsiriX-viewer software was processed. PET-CT gradient magnitude and Laplacian images could show direct information on diffusive processes for radiopharmaceuticals that enter into the cells by simple diffusion. In the case of the radiopharmaceutical {sup 18}F-FDG is necessary to include pharmacokinetic models, to make a correct interpretation of the gradient magnitude and Laplacian of counts images.

    Nuclear science in attendance on medicine or from Radium to Radiopharmaceuticals. By a brief historical reminder of the evolution of the radioactivity and development of nuclear science, we could see a very early interest and application of the radioactivity in the medical field. Main steps: Detection of natural radioactivity/Discovery of artificial radioactivity/First treatment of leukaemia and thyroid/First nuclear reactor/First radioisotope laboratory in hospital/First scintigraphy/First radiopharmaceutical/First cyclotron and cyclotron products/First immunoscintigraphy/Biotechnology and radioisotope/Evolution of technics [equipment for diagnosis (imaging, scintigraphy) and therapy]/Evolution of production technics and concept of products (generators of Technetium) and machines, reactor, cyclotron/Evolution of importance and interest of nuclear medicine/Creation of international association of nuclear medicine and producers (example ARPR)/Evolution of safety and pharmaceuticals regulation. After the sixties, period extremely rich in invention of products, characterized by a high fertility specially due to a non-restrictive regulation in terms of safety and pharmaceutical consideration, the evolution of technics, the importance of costs (investment, research, healthcare and the evolution of the regulations) have smoothly but continuously transformed the contexts and different actors. Consequences and facts: Rationalization and standardization of the catalogues, total integration of radiopharmaceuticals into the pharmaceutical laws, stop of nuclear research reactors, increase of number of cyclotrons, transformation of size and role of the producers and nuclear centers, risk in supply of some raw materials like Molybdenum, medical nuclear application as a worldwide business

    Recent improvements in the understanding of the physiologic and biologic mechanisms of health and disease have led to an expansion of nuclear medicine applications both in clinical studies and research. Advances in radiopharmaceutical development, instrumentation and computer processing have resulted in the implementation of Positron Emission Tomography for clinical studies, and improved treatments with radiopharmaceuticals particularly in cancer patients. There has also been an dramatic increase in the techniques available with nuclear medicine to detect and measure cellular biologic events in-vivo, which have important implications in clinical and basic science research. Nuclear medicine studies provide unique information on human physiology and remain an integral part of clinical medicine practice

    In nuclear medicine, a sequence of revolutioning research up to the simple and efficient application in routine has always then taken place when in an interdisciplinary teamwork new radiochemical tracers and/or new instrumentation had become available. At present we are at the beginning of a phase that means to be in-vivo-biochemistry, the targets of which are molecular interactions in the form of enzymatic reactions, ligand-receptor interactions or immunological reactions. The possibility to use positron-emitting radionuclides of bioelements in biomolecules or drugs to measure their distribution in the living organism by positron-emission tomography (PET) is gaining admittance into the pretentious themes of main directions of medical research. Diagnostic routine application of biochemically oriented nuclear medicine methods are predominantly expected from the transmission of knowledge in PET research to the larger appliable emission tomography with gamma-emitting tracers (SPECT).

    2013-01-01

    This volume addresses a wide range of issues in the field of nuclear medicine imaging, with an emphasis on the latest research findings. Initial chapters set the scene by considering the role of imaging in nuclear medicine from the medical perspective and discussing the implications of novel agents and applications for imaging. The physics at the basis of the most modern imaging systems is described, and the reader is introduced to the latest advances in image reconstruction and noise correction. Various novel concepts are then discussed, including those developed within the framework of the EURATOM FP7 MADEIRA research project on the optimization of imaging procedures in order to permit a reduction in the radiation dose to healthy tissues. Advances in quality control and quality assurance are covered, and the book concludes by listing rules of thumb for imaging that will be of use to both beginners and experienced researchers.

    Indications and instructions to patients for performing a positron emission tomography - PET scan are mentioned. Although PET camera was developed in 1970 its clinical indications were established in about 1998. The hybridic PET/CT- computerized tomography scanner appeared in 2001 and its clinical indications are still under discussion. These discussions refer to both the use of PET/CT as an acquisition correction and anatomic localization device for PET images (AC/A) and to its use as a diagnostic CT scan (dCT). Most of the patients submitted for a PET scan have already done a dCT scan. This was the case in 286 out of the first 300 patients referred to "Evangelismos" hospital in Athens for a PET scan. These two scans can be matched electronically. Extra cost, space, personnel and radiation absorption dose especially in children, are additional factors to be considered in using the PET/CT scanner. The specialty of Nuclear Medicine is now based on the PET camera, its best part and main equipment for molecular imaging. It is very much easier and faster for a Nuclear Medicine physician who routinely reports tomographic PET and SPET images, to be familiar with the CT images than for a Radiologist to get to "know how" about the PET camera and the whole Nuclear Medicine Department. Nuclear Medicine is about open radiation sources, molecular imaging, specific radio-pharmacology, radiobiology, radiation protection etc, while on the other hand in some countries, Nuclear Physicians have already spent, as part of their official training, six months in a Radiology Department whose function is considered to be at least 25% about the CT scanner. We come to the conclusion that the PET/CT scanner should be under the responsibility of the Nuclear Medicine Department and the Radiologist should act as an advisor.

  16. A literature review of the cost-effectiveness of nuclear medicine

    Carter, J.

    1995-01-01

    Nuclear medicine is a medical speciality that uses tiny quantities of radioactivity to produce diagnostic images. It also has a role in therapy for some thyroid diseases and certain tumours. Surveys have shown that nuclear medicine procedures are used significantly less in the UK than in many other countries in Europe. One reason may be that there is inadequate information about the clinical utility of these techniques, particularly their cost-effectiveness in clinical management. To establish what evidence was currently available about the cost-effectiveness of nuclear medicine, the British Nuclear Medicine Society commissioned a worldwide literature review in diseases of the heart, kidney, lung, bone, brain, bowel and thyroid. This volume summarises the findings of the independent study and gives details of the background, clinical utility and limitations of the different nuclear medicine procedures used in the diagnosis and treatment of each disease reviewed.

  17. Do we need a universal 'code of ethics' in nuclear medicine?

    Ramesh, Chandakacharla N; Vinjamuri, Sobhan

    2010-06-01

    Recent years have seen huge advances in medicine and the science of medicine. Nuclear medicine has been no exception and there has been rapid acceptance of new concepts, new technologies and newer ways of working. Ethical principles have been traditionally considered as generic skills applicable to wide groups of scientists and doctors, with only token refinement at specialty level. Specialist bodies across the world representing wide groups of practitioners frequently have subgroups dealing exclusively with ethical issues. It could easily be argued that the basic principles of ethical practice adopted by specialist bodies closest to nuclear medicine practice, such as radiology and oncology, will also be applicable to nuclear medicine and that time and effort need not be spent on specifying a separate code for nuclear medicine. It could also be argued that nuclear medicine is an independent specialty and some (if not most) practitioners will not be aware of the guidelines adopted by other specialist societies, and that there is a need for re-iteration of ethical principles at the specialty level and on a worldwide scale.In this article we would like to present a brief history of medical ethics, discuss some of the advances in nuclear medicine and their associated ethical aspects, as well as list a framework of principles for consideration, should a specialist body deem it suitable to establish a 'code of ethics' for nuclear medicine.

  18. A manual of nuclear medicine procedures

    Das, B.K.; Noreen Norfaraheen Lee Abdullah

    2012-01-01

    Nuclear medicine is a fast growing specialty. The procedures provide quantitative parameters of organ functions required for modern practice of medicine. With the development of new machines and increased application of computer software, the procedures are under continuous change. Some procedures have become outdated or redundant while new methods have been introduced to enhance the quality of information obtained from a particular application. Although there are a few books published abroad to inform doctors and technical staff about the procedures, a comprehensive source to give quick information about how different test are performed, particularly the new developments and the expected outcome both in normal and abnormal cases has been a long felt need. The physician ordering a Nuclear Medicine test also needs to know what patient preparations are required for optimal results, how to satisfy the queries of the patient particularly in respect of radiation exposure which sometimes can be a major concern of the patient. This manual has been prepared not only to describe technical details of various procedures that are currently practiced in Nuclear Medicine, but also to provide quick information for the doctors and health care personnel on how to inform the patients about the investigation for which they are being referred and how to interpret the results. Since there is no such comprehensive book published yet in Asia including South-East Asia, it is likely to be in great demand in the region. All students of Master Degree, M.D., DRM, DMRIT, M.Sc. (Nuclear Medicine) and technologists already working in various diagnostic centers will likely buy this book. General practitioners and specialists who refer patients for different radioisotope investigations may find this book useful for quick reference. (author)

    Nuclear medicine can synergistically contribute to the sports medicine field, in the management of sports-related stress injures. Bone scintigraphy is commonly requested for evaluation of athletes with pain. Three-Phase 99m Tc MDP Bone Scan has emerged as the imaging reference standard for diagnosing such injuries. The inherently high-contrast resolution of the bone scan allows early detection of bone trauma and becomes positive within six to seventy-two hours after the onset of symptoms. The bone scan is able to demonstrate stress injuries days to weeks before the radiograph

    Since the introduction of nuclear medicine in 1959, Korea accomplished a brilliant development in terms of both clinical practice and research activities, which was mainly due to the dedication of nuclear medicine specialists, consisting of physicians, technicians, and scientists, and strong support from the Korean Government. Now, Korea has 150 medical institutes, performing approximately 561,000 nuclear imaging procedures and 11.6 million in vitro studies in 2008, and ranked fourth in the number of presentations at the Annual Meeting of the Society of Nuclear Medicine (SNM) in 2008. The successful progress in this field has allowed Korea to focus on the international promotion of nuclear medicine, especially in the developing and underdeveloped countries. In consequence, the Asian Regional Cooperative Council for Nuclear Medicine (ARCCNM) was established in 2001, and Seoul hosted the 9th Congress of the World Federation of Nuclear Medicine and Biology (WFNMB) in 2006. In the future, Korea will strive to sustain its rate of advancement in the field and make every effort to share its progress and promote the exchange of scientific information at the international level.

    Physicists have created remarkably sophisticated instruments for the performance of experiments. With variable phase lags many of these have become useful in technology. In the medical field NMD techniques have become commonplace under the rubric of Magnetic Resonance Imaging. Particle physics has developed sophisticated detectors for both charged and neutral particles. Many of these also have been adapted to medical uses. In both radiology and nuclear medicine, pixel detectors based on designs originating at large-scale colliders, are becoming highly useful in replacing film and NaI as the primary means of X-ray and (-ray detection. Coupled with high-speed work stations, these new techniques allow exciting new imagining modalities. Many of these are based on the handling of digital images originally developed for astronomy. Thus, once again, fundamental science is making large contributions to the development of technology. In this talk, various examples of developments in digital mammography and digital detectors for nuclear medicine will be given. The possibilities for telemedicine will be discussed. (author)

    Multi-modality imaging with SPECT-CT in orthopaedics combines the excellent sensitivity of scintigraphy with the morphological information of CT as a key for specific interpretation of findings in bone scans. The result is an imaging modality with the clear potential to prove of value even in a competitive setting dominated by MRI, and to significantly add to diagnostic imaging in orthopaedics. SPECT-CT is of great value in the diagnostic evaluation after fractures, and - in contrast to MRI - it is well suited for imaging in patients with osteosyntheses and metallic implants. In sports medicine, SPECT-CT allows for a sensitive and specific detection of osseous stress reactions before morphological changes become detectable by CT or MRI. In patients with osseous pain syndromes, actively evolving degenerative changes as a cause of pain can be identified and accurately localized. Further, particularly prospective diagnostic studies providing comparative data are needed to strengthen the position of nuclear imaging in orthopaedics and sports medicine and to help implementing SPECT/CT in diagnostic algorithms.

    The aim of the present work is to study the performance of scintillators currently used in PET and animal PET systems, under conditions met in radiation therapy and PET/CT imaging. The results of this study will be useful in applications where both CT and PET photons as well as megavoltage cone beam CT (MV CBCT) photons could be detected using a common detector unit. To this aim crystal samples of GSO, LSO, LYSO, LuYAP and YAP scintillators, doped with cerium (Ce+3) were examined under a wide energy range of photon energies. Evaluation was performed by determining the absolute luminescence efficiency (emitted light flux over incident X-ray exposure) in the energy range employed in X-ray CT, in Nuclear Medicine (70 keV up to 662 keV) and in radiotherapy 6 MV (approx. 2.0 MeV mean energy)-18 MV (approx. 4.5 MeV mean energy). Measurements were performed using an experimental set-up based on a photomultiplier coupled to a light integration sphere. The emission spectrum under X-ray excitation was measured, using an optical grating monochromator, to determine the spectral compatibility to optical photon detectors incorporated in medical imaging systems. Maximum absolute luminescence efficiency values were observed at 70 keV for YAP:Ce and LuYAP:Ce and at 140 keV for LSO:Ce, LYSO:Ce and GSO:Ce. Highest absolute efficiency between the scintillators examined was observed for LSO:Ce, followed by LYSO:Ce. The detector optical gain (DOG) exhibited a significant variation with the increase of energy between 70 keV to 2.0 MeV. All scintillators exhibited low compatibility when combined with GaAsP (G5645) photodetector.

    Nuclear medicine and functional imaging were born of the CEA's ambition to promote and develop nuclear applications in the fields of biology and health. Nuclear medicine is based on the use of radioactive isotopes for diagnostic and therapeutic purposes. It could never have developed so rapidly without the progress made in atomic and nuclear physics. One major breakthrough was the discovery of artificial radioelements by Irene and Frederic Joliot in 1934, when a short-lived radioactive isotope was created for the first time ever. Whether natural or synthetic, isotopes possess the same chemical properties as their non-radioactive counterparts. The only difference is that they are unstable and this instability causes disintegration, leading to radiation emission. All we need are suitable detection tools to keep track of them. 'The discovery of artificial radioelements is at the root of the most advanced medical imaging techniques'. The notion of tracer dates back to 1913. Invented by George de Hevesy, it lies at the root of nuclear medicine. By discovering how to produce radioactive isotopes, Irene and Frederic Joliot provided biology researchers with nuclear tools of unrivalled efficiency. Today, nuclear medicine and functional imaging are the only techniques capable of giving us extremely precise information about living organisms in a non-traumatic manner and without upsetting their balance. Positron emission tomography (PET) and nuclear magnetic resonance imaging (MRI) are the main imaging techniques used at the CEA in its neuro-imaging research activities. These techniques are now developing rapidly and becoming increasingly important not only in the neuroscience world, but also for innovative therapies and cancer treatment. (authors)

  5. Justification of the hybrid nuclear medicine examinations

    International Nuclear Information System (INIS)

    Garcheva-Tsacheva, Marina B.

    2015-01-01

    The annual frequency of nuclear medicine examinations is increasing worldwide. This is partly a consequence of the recently introduced single photon emission tomography, combined with computed tomography, and positron emission tomography, combined with computed tomography, techniques, which combine functional, metabolic and morphological information important for the diagnosis of many diseases. However, since the effective radiation dose is the sum of the dose of two components, the hybrid examinations result in increased patient exposure. Accordingly, their justification becomes mandatory. It starts with their clinical importance-the opportunity to resolve a clinical problem decisive for patients' management. Knowledge of the indications, contraindications and the examinations' limitations is the responsibility of the nuclear medicine physician, as well as the choice of the most adequate examination and protocol. In conclusion, the cost and the accessibility of the examinations should not be the principal consideration as opposed to the diagnostic value and the exposure. Flexible protocols and algorithms should be used for hybrid nuclear medicine examinations. (authors)

    Estimates of the risks of exposing an embryo or fetus to radiation are discussed. Recommendations are made about the policies a nuclear medicine department should develop for handling cases of accidental irradiation of an embryo or fetus. The choices available where a known pregnancy is involved and diagnostic radiology is required are outlined. Only necessary examinations should be performed and care taken to avoid or minimise irradiation of the fetus. The nuclear medicine physician must be prepared to make (and defend if necessary) an informed decision on whether to proceed with an examination and must also be in a position to discuss the risks with anxious parents

    In this paper the practical problem of nuclear medicine gamma counters calibration has been solved by using dose calibrators CRC-15R with standard error ±5%. The samples from technetium generators have been measured both by dose calibrators CRC-15R and gamma counter ICN Gamma 3.33 taking into account decay correction. Only the linear part of the curve has practical meaning. The advantage of this procedure satisfies the requirements from international standards: the calibration of sources used for medical exposure be traceable to a standard dosimetry laboratory and radiopharmaceuticals for nuclear medicine procedures be calibrated in terms of activity of the radiopharmaceutical to be administered.

    The technologies used in nuclear medicine for diagnostic imaging have evolved over the last century, starting with Röntgen’s discovery of X rays and Becquerel’s discovery of natural radioactivity. Each decade has brought innovation in the form of new equipment, techniques, radiopharmaceuticals, advances in radionuclide production and, ultimately, better patient care. All such technologies have been developed and can only be practised safely with a clear understanding of the behaviour and principles of radiation sources and radiation detection. These central concepts of basic radiation physics and nuclear physics are described in this chapter and should provide the requisite knowledge for a more in depth understanding of the modern nuclear medicine technology discussed in subsequent chapters.

  15. Radiation exposure of nuclear medicine procedures in Germany

    2005-01-01

    Nuclear Medicine procedures offer the possibility to detect abnormalities on the basis of physiological and metabolic changes and to treat a growing number of diseases in human beings. However, the use of radiopharmaceuticals for nuclear medicine examinations causes a significant component of the total radiation exposure of populations. In Germany it is an essential task of the Federal Office for Radiation Protection to determinate and assess radiation exposure of the population due to nuclear medicine diagnostics and therapy. An important input for this task is the frequency of nuclear-medical examinations with application of ionising radiation and the radiation exposure of patients related to the various procedures. Additional implementation of age- and gender-specific data today allows more exact risk stratification in focusing on different subgroups of patients. Moreover, the collective effective dose as well as the per caput effective dose of the German population may be estimated and compared with earlier collected data or foreign countries. These data reveal where the indication should be questioned particularly critically and if the dose for the various examinations can be reduced and, thus, contribute to the definition of diagnostic reference levels for nuclear medicine procedures in Germany with the aim of both a sufficient image quality and a minimum of radiation exposure. Exceeding the high- as well as the low-values requires documentation and explanation. (orig.)

    This article gives an evidence-based overview about several special indications for scintigraphy in imaging infection and inflammation. In diagnosing and evaluating the extent of inflammatory bowel disease, the scintigraphy with {sup 99m}Tc-HMPAO labelled leucocytes remains the standard evaluation in Nuclear Medicine. Appendicitis can be proven or excluded with a high grade of certainty both by {sup 99m}Tc-labelled monoclonal antigranulocytic antibodies and FAb'-fragments and by in-vitro labelled leucocytes. In endocarditis a late SPECT (20-24 h p. i.) with a {sup 99m}Tc-labeled anti-CD66 monoclonal antibody is a useful adjunct to echocardiographic techniques. In infected vascular prostheses, {sup 99m}Tc-HMPAO-labelled autologous leucocytes remain the standard of Nuclear Medicine although [{sup 18}F]FDG-PET or [{sup 18}F]FDG-PET / CT may exhibit a higher diagnostic accuracy.

    Positron Emission Tomography (PET) has been available in number of centers for more than 25 years, but its use was not wide spread until 10 years ago. In Bulgarian PET/CT was installed for the first time in 2009 in Nuclear Medicine Department in University Hospital St. Marina in Varna, Bulgaria. As a physicists the aim for us was to consider and calculate the shielding so that to protect the people and the staff. The purpose of this paper is calculating and analysis of the radiation protection and shielding of Nuclear Medicine Center including PET/CT center situated in University Hospital St. Marina in Varna, Bulgaria. Following the Recommendation of International Commission of Radiation Protection (ICRP) Report 60, Report 73, American Association of Physics in Medicine (AAPM) Task Group 108: PET and PET/CT Shielding Requirements, Medical Physics, DIN 6844-3, Installation of Nuclear Medicine; Radiation protection calculation and the Bulgarian regulations in NM, the new Department was made. The design of the Existing Department was renovated following the requirements for PET/CT Center. The shielding was calculated for imaging room as well as the uptake room, resting room, the PET control room, places above and under the facility, patient WCs and other surrounding laboratories and stuff cabinets. The radiotracer used for the examinations is fluoro-2-desixyglucose (FDG). FDG is labeled with F-18, whose time of flight is only 109min, but it is positron emitting. The energy of annihilation is 511keV. The aim was achieved. The Department was opened. It is working now with about 15 patients every day. The dose rates measured with personal TLD’s for the last 5 years for the stuff are under 3mSv. As the average dose is around 1mSv, and the doses over 1mSv are only for nurses who injected the FDG.

    Addiction to illicit drugs in one of today's most important social issues. Most addictive drugs lead to irreversible parenchymal changes in the human brain. Neuroimaging data bring to light the pharmacodynamics and pharmacokinetics of the abused drugs, and demonstrate that addiction is a disease of the brain. Continuous researches better illustrate the neurochemical alterations in brain function, and attempt to discover the links to consequent behavioral changes. Newer hypotheses and theories follow the numerous results, and more rational methods of approaching therapy are being developed. Substance abuse is on the rise in Korea, and social interest in the matter as well. On the other hand, diagnosis and treatment of drug addiction is still very difficult, because how the abused substance acts in the brain, or how it leads to behavioral problems in not widely known. Therefore, understanding the mechanism of drug addiction can improve the process of diagnosing addict patients, planning therapy, and predicting the prognosis . Neuroimaging approaches by nuclear medicine methods are expected to objectively judge behavioral and neurochemical changes, and response to treatment. In addition, as genes associated with addictive behavior are discovered, functional nuclear medicine images will aid in the assessment of individuals. Reviewing published literature on neuroimaging regarding nuclear medicine is expected to be of assistance to the management of drug addict patients. What's more, means of applying nuclear medicine to the care of drug addict patients should be investigated further.

    2013-01-01

    Full text: Introduction: Like any nuclear medicine study, bone scintigraphy is a diagnostic procedure associated with intravenous injection of a radioactive isotope with low activity - radiopharmaceutical. But recently in clinical practice hybrid imaging methods such as SPECT/ CT (Single Photon Emission Tomography - Computed Tomography) has necessitated, as they provide comprehensive information about the function and structure of the studied organ. Materials and methods: In the Department of Nuclear Medicine in The Specialized Hospital for Active Treatment of Oncology Diseases in Sofia it is installed a two-detector SPECT/CT gamma camera Siemens Symbia T2, on which the whole range of nuclear medicine studies in oncology practice is held: bone scintigraphy, 99mTc - MIBI scintigraphy, Lymphoscintigraphy, somatostatin receptor scintigraphy, tireostsintigraphy with 131I/99mTc, dynamic nephroscintgraphy etc. The working algorithm upon choosing the clinical protocols, and setting the parameters for scanning are complied with the requirements and recommendations established by the nuclear medicine standard. The presented are results from studies of patients when after whole body bone scintigraphy, an additional SPECT/CT study was conducted for more accurate diagnostic and interpretation of the results. Results: Practical introduction of hybrid imaging methods require from technicians besides knowledge in working with radioactive sources and practical skills such as: the selection of the matrix size, number of projections, choice of trajectory - circular or elliptical, set the appropriate degree of rotation of the detector (180 or 360). Particularly important in the processing of MR images is the appropriate choice of algorithm of reconstruction: filtered backprojection or iterative reconstruction methods. In MR images processing there is no rule for the optimal filter, which is why the quality of the reconstructed image depends primarily on the experience of the operator

    International Nuclear Information System (INIS)

    O'Doherty, M.J.; Kent and Canterbury Hospital, Canterbury; Nunan, T.O.

    1993-01-01

    The human immunodeficiency virus (HIV) infection and its associated illnesses in a relatively young population of patients provides an expanding role for nuclear medicine. The disease enforces a review of each department's infection control procedures. It has also resulted in an increase in the number of patients presenting with diseases such as Pneumocystis carinii pneumonia, Kaposi's sarcoma etc. which prior to the HIV epidemic were extremely rare. Thus in high risk patients the interpretation of abnormalities in nuclear medicine scans needs to include the spectrum of opportunistic infections and unusual tumours. The presence of opportunistic infections in the severely immunocompromised patient has led to the development of techniques not normally used, i.e. lung 99 Tc m -diethylenetriamine pentaacetate (DTPA) transfer/clearance, donor leukocyte scanning to allow rapid diagnosis of an abnormality. Radionuclide techniques are also used to monitor the effect of therapy directed at the HIV itself or against opportunistic infections. This review covers aspects of infection control as well as the use of radionuclides to investigate specific problems related to HIV infection and therapy of the associated disease processes.

  8. PET/CT Atlas on Quality Control and Image Artefacts

    International Nuclear Information System (INIS)

    2014-01-01

    Combined positron emission tomography (PET)/computed tomography (CT) imaging has become a routine procedure in diagnostic radiology and nuclear medicine. The clinical review of both PET and PET/CT images requires a thorough understanding of the basics of image formation as well as an appreciation of variations of inter-patient and intra-patient image appearance. Such variations may be caused by variations in tracer accumulation and metabolism, and, perhaps more importantly, by image artefacts related to methodological pitfalls of the two modalities. This atlas on quality control (QC) and PET/CT artefacts provides guidance on typical image distortions in clinical PET/CT usage scenarios. A number of cases are presented to provide nuclear medicine and radiology professionals with an assortment of examples of possible image distortions and errors in order to support the correct interpretation of images. About 70 typical PET and PET/CT cases, comprised of image sets and cases, have been collected in this book, and all have been catalogued and have explanations as to the causes of and solutions to each individual image problem. This atlas is intended to be used as a guide on how to take proper QC measures, on performing situation and problem analysis, and on problem prevention. This book will be especially useful to medical physicists, physicians, technologists and service engineers in the clinical field

    1997-01-01

    Since two years ago nuclear medicine service of Laennec Hospital has implemented transmission and distribution networks of scintigraphic images. A new stage was reached at present by developing an Intranet and Extranet system for nursing units and other services of nuclear medicine. The Intranet link to the services of Laennec Hospital and AP HP is based on a image server connected to the service gamma camera and, after a possible post-processing, the images are transmitted in PCX format by e-mail, attached to the medical record. For communication between nuclear medicine services, a heavier procedure making use of a program for image processing under inter-file standards has been implemented. To achieve the Extranet link with services and physicians of town, exterior to AP HP, a procedure was installed which allows reaching any nursing unit or town physicians having at their disposal e-mail on a secured network. This procedure will be generalized when the Health secured network, linking the medical bodies to Health insurance institutions, will be operational. The interactive tele-medicine will be achieved by means of a procedure based on Internet cooperative tools (wild cards, video- and vision-conferences) which will permits in all situations an interactive work on all the transmitted patient files

    1995-01-01

    A survey of all member societies of the European Association of Nuclear Medicine has shown that a satisfactory degree of harmonisation exists for the quality assurance of the preparation and handling of radiopharmaceuticals and the performance of nuclear medicine instrumentation. However, variations were found in acquisition protocols, data analysis and the interpretation and presentation of clinical results. Harmonisation of these areas of a nuclear medicine investigation would help ensure the overall quality. A European initiative is proposed to collect and collate procedures in these areas in order to produce a reference framework of good practice for the acquisition, analysis and interpretation of nuclear medicine investigations. This would involve collaboration between national societies and exchange of information with and support from European organisations, taking into account relevant international activities. The reference framework should be compatible with quality management guidelines. (orig.)

  13. The importance of HIFAR to nuclear medicine

    Wood, N.R.

    1997-01-01

    Since its official opening on 26 January 1960, the HIFAR research reactor operated by the Australian Nuclear Science and Technology Organisation (ANSTO) at Lucas Heights near Sydney has been used to support an expanding nuclear medicine market. HIFAR has characteristics which make it very suitable for this role and the effect has been to make ANSTO the dominant supplier of reactor-based radiopharmaceuticals in Australia and a significant exporter. While HIFAR has capacity to support limited increased production, its future requires government decisions. The author concluded that the absence of an operational research reactor in Australia and the lack of another local source of neutrons could directly affect the practice of nuclear medicine in the country and the level of presently increasing exports

    1998-01-01

    Therapeutic applications in nuclear medicine use high activities of 131 I in sodium iodine liquid from which is volatile at ambient temperature. Besides external exposure there is, for the nuclear medicine personnel, an internal exposure risk induced by 131 iodine inhalation. So we tried to assess this risk among the personnel in a nuclear medicine department. We used direct method for measuring 131 radioactivity in vivo by external counting. Gamma ray detector with a Nal ( TI ) probe positioned near the thyroid gland allows investigation of 131 radioactivity. We realised 34 measurements among the personnel, two times at an interval of one month. The results indicate that an 131 iodine internal contamination is found. Estimated thyroid activities were ranging from 35 to 132 Bq. The highest activities has been found in the thyroid of the technicians involved in the administration of 131 iodine therapy. Therefore this values are lower than norms. This study must lead to the implementation control of the 131 iodine internal contamination in order to optimise the personnel protection in nuclear medicine departments (author)

    The nuclear medicine department of the Val de Grace Hospital, in cooperation with the Radiological Protection Army Service, has performed an evaluation of the staff's radio-exposure based on routine dosimetry for six months. The most exposed people are the technicians (2.6 mSv/yr) and the nurse (1.7 mS/yr). The nuclear medicine physicians (0.6 mSv/yr) and the secretaries (0.07 mSv/yr) are far less exposed. The most irradiant occupations are the preparation and the injection of the radiopharmaceuticals (18 mSv/dy) and the realization of the Positron Emission Tomography examinations (19 mSv/dy). The increasing number of PET exams and the development of new tomographs, requiring higher activities, will still increase the exposition level of this working post. This study demonstrates that the exposition doses in nuclear medicine are low compared to the regular limits. Based on these results, only the technicians and the nurse are relevant to the A class. However, these dose levels cannot be neglected for particular positions such as the injection and the PET management. (author)

    Radionuclides and radiopharmaceuticals play a kay role in nuclear medicine, both in diagnostics and therapy. Incorporation of radionuclides into biomolecules, and syntheses of radiolabelled compounds of high biological selectivity are a task for radiochemists working in the multidisciplinary field of radiopharmaceutical chemistry. The most commonly used radionuclide, 99m Tc, owes this popularity to its both nearly ideal nuclear properties in respect to medical imaging, and availability from inexpensive radionuclide generators. Also numerous other radionuclides are widely used for medical imaging and therapy. Labelling of biomolecules with radioiodine and various positron emitters is getting increasingly important. This review describes some chemical and radiochemical problems we meet while synthesizing and using 99m Tc-radiopharmaceuticals and radioiodine-labelled biomolecules. Also represented are the recent developments in the design and use of the second generation radiopharmaceuticals based on bifunctional radiochelates. Several principal routes of fast chemical synthesis concerning incorporation of short-lived positron emitters into biomolecules are outlined as well. The search for chemical structures of high biological selectivity, which would be activated by slow neutrons, is related to the method of Neutron Capture Therapy, an interesting option in nuclear medicine.

    The recent introduction of hybrid systems combining a SPECT and a CT in nuclear medicine, greatly improved the diagnostic accuracy for particular clinical indications, due to the possible attenuation and/or scatter correction of the SPECT functional images and the availability of helpful anatomic information. Although the gamma cameras performances are noticeably comparable, the associated CT furnished by the manufacturer are relatively different from each other. Whatever the system is, the introduction of CT in the nuclear diagnostic process results in a significant increase of the patient dose. This dose increase should be justified and optimized considering both the clinical question and the CT settings available on these systems. The installation of a hybrid system must be accompanied by the management of a documentary quality insurance program, jointly developed by the technologists, physicists and physicians, both covering its clinical use and the associated dosimetry issues as monitoring its performances. Particular quality control procedures have to be defined because of the coupling between the two devices. (authors)

  20. Quantitative Analysis in Nuclear Medicine Imaging

    CERN Document Server

    2006-01-01

    This book provides a review of image analysis techniques as they are applied in the field of diagnostic and therapeutic nuclear medicine. Driven in part by the remarkable increase in computing power and its ready and inexpensive availability, this is a relatively new yet rapidly expanding field. Likewise, although the use of radionuclides for diagnosis and therapy has origins dating back almost to the discovery of natural radioactivity itself, radionuclide therapy and, in particular, targeted radionuclide therapy has only recently emerged as a promising approach for therapy of cancer and, to a lesser extent, other diseases. As effort has, therefore, been made to place the reviews provided in this book in a broader context. The effort to do this is reflected by the inclusion of introductory chapters that address basic principles of nuclear medicine imaging, followed by overview of issues that are closely related to quantitative nuclear imaging and its potential role in diagnostic and therapeutic applications. ...

  1. Radioactive waste management of the nuclear medicine services

    International Nuclear Information System (INIS)

    Barboza, Alex

    2009-01-01

    Radioisotope applications in nuclear medicine services, for diagnosis and therapy, generate radioactive wastes. The general characteristics and the amount of wastes that are generated in each facility are function of the number of patients treated, the procedures adopted, and the radioisotopes used. The management of these wastes embraces every technical and administrative activity necessary to handle the wastes, from the moment of their generation, till their final disposal, must be planned before the nuclear medicine facility is commissioned, and aims at assuring people safety and environmental protection. The regulatory framework was established in 1985, when the National Commission on Nuclear Energy issued the regulation CNEN-NE-6.05 'Radioactive waste management in radioactive facilities'. Although the objective of that regulation was to set up the rules for the operation of a radioactive waste management system, many requirements were broadly or vaguely defined making it difficult to ascertain compliance in specific facilities. The objective of the present dissertation is to describe the radioactive waste management system in a nuclear medicine facility and provide guidance on how to comply with regulatory requirements.

    Oliveira, Silvia Maria Velasques de

    2005-01-01

    With the aim of characterizing nuclear medicine procedures performed in Brazil, activities of radiopharmaceuticals used and effective doses to patients, data was collected from nuclear medicine institutions in three regions of the country, namely the Southeast, the Northeast and the South regions, representing public hospitals, university hospitals, private and philanthropic institutions with low, medium and high levels of consumption of radiopharmaceuticals. The three chosen regions are responsible for 92% of radiopharmaceutical consumption and imaging equipment in the country. Accordingly, it was requested of some participating institutions to fulfill manually from individual patients data, to record gender, age, weight, height and activities used, for each type of exam as well as the equipment used. In others, the researcher collected data personally. Per institution, nuclear medicine diagnostic procedures ranged from 700 to 13,000 per year, most of which are myocardial and bone imaging procedures, and imaging equipment ranged, from 1 to 8 machines, one or two head SPECT's (hybrid or not). 26.782 patients protocols were analysed, 24.371 adults and 2.411 children and teenagers. For adult patients, differences were observed in the amount of activities used in diagnostic procedures between public and private institutions, with lower average activities used in public institutions. Activities administered to children and their effective doses were difficult to evaluate due to the incompleteness of individual records. Appropriate individual patient records could be adopted without affecting hospitals routine and contributing for a comprehensive evaluation of the radiation protection of nuclear medicine patients. Data from 8.881 workers were analysed, 346 working at nuclear medicine institutions. For monitored workers and measurably exposed workers in nuclear medicine, the values 2.3 mSv and 5.4 mSv, respectively, for effective annual doses are greater than data

    Functional or morphofunctional imaging modalities are used in myeloma patients for the diagnosis and therapy management within research protocols. Despite new staging criteria, which take into account the viability of a myeloma lesion, positron emission tomography (PET) is not used routinely. The impact of PET is therefore open. The role of PET and PET computed tomography (PET-CT) for the diagnosis and therapy management is discussed. The use of PET with 18F-fluorodeoxyglucose (FDG) allows the measurement of viable myeloma lesions and correlates with the stage of disease. A negative FDG examination correlates with a better prognosis. Furthermore, the number of focal lesions as well as the whole functional volume of myeloma lesions in FDG have a prognostic impact. Several studies have demonstrated the impact of FDG for the assessment of therapy monitoring and show that FDG is an earlier indicator for therapy response as compared to magnetic resonance imaging (MRI). The CT component of the new hybrid systems allows the assessment of osteolytic lesions in CT and their viability in FDG. The combination of PET with an MRT scanner allows the simultaneous measurement of bone marrow infiltration, focal lesions and their viability. The use of modern hybrid scanners, such as PET-CT and PET-MRT facilitates the simultaneous measurement of viable myeloma lesions, osteolytic lesions and bone marrow infiltration in the whole body; therefore, it is expected that these imaging modalities will play a greater role both in diagnosis and therapy management.

    Education in Nuclear Physics, Medical Physics and Radiation Protection in medicine and veterinary medicine studies on Belgrade University is an integral part of the curriculum, incorporated in different courses of graduate and post-graduate studies. During graduate studies students get basic elements of Nuclear Physics through Physics and/or Biophysics courses in the 1 st year, while basic knowledge in Medical Physics and Radiation Protection is implemented in the courses of Radiology, Physical Therapy, Radiation Hygiene, Diagnostic Radiology and Radiation Therapy in the 4 th or 5 th year. Postgraduate studies offer MSc degree in Radiology, Physical Therapy, while courses in Nuclear Physics, Nuclear Instrumentation, Radiation Protection and Radiology are core or optional. On the Faculty of Veterinary Medicine graduated students may continue their professional education and obtain specialization degree in Radiology, Physical Therapy or Radiation Protection. On the Faculty of Medicine there are specialization degrees in Medical Nuclear Physics. Still, a closer analysis reveals a number of problems both from methodological and cognitive point of view. They are related mostly to graduate students ability to apply their knowledge in practise and with the qualifications of the educators, as those engaged in graduate studies lack basic knowledge in biological and medical sciences, while those engaged in post graduate studies mostly lack basic education in physics. Therefore, a reformed curricula resulting from much closer collaboration among educators, universities and professional societies at the national level should be considered. (author)

    Pascual, Thomas N B

    2016-08-01

    This essay will explore the critical issues and challenges surrounding lifelong learning for professionals, initially exploring within the profession and organizational context of nuclear medicine practice. It will critically examine how the peer-review process called Quality Management Audits in Nuclear Medicine Practice (QUANUM) of the International Atomic Energy Agency (IAEA) can be considered a lifelong learning opportunity to instill a culture of quality to improve patient care and elevate the status of the nuclear medicine profession and practice within the demands of social changes, policy, and globalization. This will be explored initially by providing contextual background to the identity of the IAEA as an organization responsible for nuclear medicine professionals, followed by the benefits that QUANUM can offer. Further key debates surrounding lifelong learning, such as compulsification of lifelong learning and impact on professional change, will then be weaved through the discussion using theoretical grounding through a qualitative review of the literature. Keeping in mind that there is very limited literature focusing on the implications of QUANUM as a lifelong learning process for nuclear medicine professionals, this essay uses select narratives and observations of QUANUM as a lifelong learning process from an auditor's perspective and will further provide a comparative perspective of QUANUM on the basis of other lifelong learning opportunities such as continuing professional development activities and observe parallelisms on its benefits and challenges that it will offer to other professionals in other medical speciality fields and in the teaching profession.

Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up-to-date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, computed tomography, nuclear medicine, and mammography.

    In aim of this study was to develop a draft for a new code practice for radiation protection in nuclear medicine that meets the current relevant international recommendation. The draft includes the following main fields: methods of radiation protection for workers, patients and public. Also, the principles of safe design of nuclear medicine departments, quality assurance program, proper manipulation of radiation sources including radioactive waste and emergency preparedness and response. The practical part of this study includes inspections of three nuclear medicine departments available in Sudan so as to assess the degree of compliance of those departments with what is stated in this code. The inspection missions have been conducted using a checklist that addresses all items that may affect radiation raincoat issues in addition to per formin area radiation monitoring around the installation of the radioactive sources. The results of this revealed that most of the departments do not have effective radiation protection program which in turn could lead to unnecessary exposure to patients, public and workers. Finally, some recommendations are given that - if implemented - could improve the status of radiation protection in nuclear medicine department. (Author)

  7. The application of nuclear-medicine methods in veterinary medicine

    1996-01-01

    X-radiography and ultrasound imaging are well established and widely used in veterinary practice, but it is not the same situation with radioisotope imaging. In veterinary practice the above mentioned methods of nuclear medicine are developed only in two countries in Europe. That is not doubt due, so bar, to the difficulties in obtaining satisfactory supply of radioisotopes and to the relatively high cost of scanning equipment. However, in collaboration with the Department of Radiation Protection and Nuclear Medicine of the Medical Faculty in Zagreb, Croatia, we have chance to develop the use of those methods in clinical veterinary practice in Zagreb. That is way in this paper an overview of the application of radioisotopes imaging in veterinary medicine is given. In small animals skeletal changes, lung perusions, brain lesions, space occupying lesions in the liver and its function and hearth function can be usefully searched by a gamma camera and its associated computer. In equine practice scintigraphy of bones, liver, hearth, pulmonary circulation and ventilation is described. The largest amount of radioactive material is used during gamma camera scanning of the skeletons of horses. In this cases the radiation dose 1-2 m from the animal is approximately 3 μSv/h. That is why the protection of personal involved in radioisotope scanning in veterinary medicine must be also regulated by low of radiation protection. Also, the animals should be confined to a controlled area for 2-3 days after scanning before being returned to their owners. After this period the area must be cleaned. (author)

    characteristics of this radionuclide limited it's broad application and 87mSr did not improve this situation. Only when 99mTc phosphonates were developed by Subramanian the importance of bone scintigraphy became apparent: The excellent imaging properties of these radiotracers showed, that abnormal bone metabolism could be visualized even before morphological alterations in the skeleton become visible on radiographies or even CT-scans. Moreover, proposals made earlier to use 32P or 89Sr for palliation of pain in patients with disseminated skeletal metastases were picked up again and led also to other radiopharmaceuticals (186Re-HEDP, 153Sm-EDTMP, 117mSn-DTPA) which are applied today for the same purpose with very good success. Therefore Nuclear Medicine today has a broad program for diagnostic and therapeutic approaches to diseases of bone and joints. In bone scanning the high sensitivity led to inclusion of this method for routine staging and re-staging programs in a variety of cancer forms which have a trend to develop bone metastases (e.g. breast, lung, prostate, melanoma) but the low specificity of abnormal patterns on such scans can impair the diagnostic value of the technique. To increase specificity and to define inflammatory lesions, radiotracers used for ''inflammation scanning'' were introduced such as labeled granulocytes, 99mTc Human Immunoglobuline and others but also a simple modification of bone scanning - triple phase bone scintigraphy - was used. Recently the excellent properties of 18F for PET of the skeleton were rediscovered again and emission CT scanning - possibly with overlay with transmission CT or MRT pictures - can enhance the diagnostic impact of radionuclide bone studies.

    To review the findings on (18)F-FDG PET-CT in patients with fever of unknown origin lasting more than 7 days. This retrospective descriptive observational study included 93 (18)F-FDG PET-CT studies to detect a fever-causing focus done at three nuclear medicine centers from October 2006 through February 2014. A nuclear medicine specialist and a radiologist reviewed the images for foci of pathological uptake; another specialist's opinion resolved discrepancies. The findings on (18)F-FDG PET-CT studies were checked against clinical and/or histological findings. Abnormal (18)F-FDG uptake on PET-CT that could explain the cause of the fever was found in 52 (56%) of the 93 studies, and the cause of the fever was confirmed in 50 of these 52 studies. In the 50 cases in which the cause of the fever was confirmed, infection was the most common cause (54%), followed by noninfectious inflammatory disease (28%) and tumors (18%). (18)F-FDG PET-CT is useful in diagnosing the cause of prolonged febrile illness, so it might be practical to use it earlier in the diagnostic process. Copyright © 2014 SERAM.

    This paper aims to demonstrate the importance of the regulatory inspections carried out by the Brazilian regulatory body in the area of nuclear medicine. The main aspects observed during the inspections are presented as well as the time evolution of the non-compliances, according to their occurrence by type. We also evaluate factors concerning the working of the nuclear medicine facility responsible for solving the non-compliances. The results suggest a decrease of occurrence of non-compliances with time that can be related to the strictness of the inspections and the awareness of the personnel in the nuclear medicine facilities. An analysis of radiation dose exposure levels for the professionals involved in nuclear medicine was carried out; although dose values are below regulatory dose limits, their occurrence is not decreasing satisfactorily. Results indicate the need for staff training and commitment of the responsible nuclear medicine facility staff to the radiological protection procedures. Our results also emphasise the importance of continuous coercive actions to improve the level of radiological protection in nuclear medicine facilities in compliance with the standards established by the national regulatory authority and international recommendations.

    This project was conducted to review Radiation Protection Program in Nuclear Medicine facility for diagnostic procedures which will provide guide for meeting the standard and regulatory requirements in diagnostic nuclear medicine. The main objective of this project is to keep dose to staff, patient and public as low as reasonably achievable (ALARA). The specific objectives were to review the Radiation Protection Program (RPP) in diagnostic nuclear medicine and to make some recommendation for improving the level of radiation protection in diagnostic nuclear medicine that will help to control normal exposure and prevent or mitigate potential exposure. The methodology used is review of various documents. The review showed that if the Radiation Protection Program is inadequate it leads to unjustified exposure to radiation. Finally, this study stated some recommendations that if implemented could improve the level of radiation protection in nuclear medicine department. One of the most important recommendations is that a qualified Radiation Protection Officer (RPO) should be appointed to lay down and oversee a radiation protection in the nuclear medicine department. The RPO must be given the full authority and the adequate time to enable him to perform his duties effectively. (au)

    The aim of this work was to establish a working standard for intercomparison and calibration of dose calibrators used in most of nuclear medicine facilities for the determination of the activity of radionuclides administered to patients in specific examinations or therapeutic procedures. A commercial dose calibrator, a set of standard radioactive sources, and syringes, vials and ampoules with radionuclide solutions used in nuclear medicine were utilized in this work. The commercial dose calibrator was calibrated for radionuclide solutions used in nuclear medicine. Simple instrument tests, such as linearity response and variation response with the source volume at a constant source activity concentration were performed. This instrument may be used as a reference system for intercomparison and calibration of other activity meters, as a method of quality control of dose calibrators utilized in nuclear medicine facilities.

    The use of ionizing radiation has been increased in recent years within medical applications. Nuclear Medicine Department offers both treatment and diagnosis of diseases using radioisotopes to controlled doses. Despite the great benefits to the patient, there is an inherent risk to workers which remains in contact with radiation sources for long periods. These personnel must be monitored to avoid deterministic effects. In this work, we retrospectively evaluated occupationally exposed personnel (OEP) to ionizing radiation in nuclear medicine during the last five years. We assessed both area and personal dosimetry of this department in a known Clinic in Sonora. Our results show an annual equivalent dose average of 4.49 ± 0.70 mSv in OEP without showing alarming changes in clinical parameters analyzed. These results allow us to conclude that health of OEP in nuclear medicine of this clinic has not been at risk during the evaluated period. However, we may suggest the use of individual profiles based on specific radiosensitivity markers.

Therefore, we aimed to compare the performance of whole-body magnetic resonance imaging (WB-MRI with that of 18F-FDG PET/CT for lesion detection and initial staging in patients with aggressive or indolent lymphoma. Materials and methods: We searched the MEDLINE, EMBASE, and CENTRAL databases for studies that compared WB-MRI with 18F-FDG PET/CT for lymphoma staging or lesion detection. The methodological quality of the studies was assessed using version 2 of the “Quality Assessment of Diagnostic Accuracy Studies” tool. The pooled staging accuracy (µ of WB-MRI and 18F-FDG PET/CT for initial staging and for assessing possible heterogeneity (χ2 across studies were calculated using commercially available software. Results: Eight studies comprising 338 patients were included. In terms of staging, the meta-analytic staging accuracies of WB-MRI and 18F-FDG PET/CT for Hodgkin lymphoma and aggressive non-Hodgkin lymphoma (NHL were 98% (95% CI, 94%–100% and 98% (95% CI, 94%–100%, respectively. The pooled staging accuracy of 18F-FDG PET/CT dropped to 87% (95% CI, 72%–97% for staging in patients with indolent lymphoma

    The International Atomic Energy Agency is organizing its first international conference on 'Clinical PET and Molecular Nuclear Medicine'. Medical imaging technologies have undergone explosive growth over the past two decades. Today, imaging is at a crossroad, with molecular targeted imaging agents expected to broadly expand the capabilities of conventional anatomical imaging methods. Observing molecular interactions in the living body by the radiotracer technique has become known as 'molecular nuclear medicine'. Molecular nuclear medicine techniques analyze cellular biochemistry and its relationship to disease processes expressed in tissue and organ dysfunction, for diagnostic and therapeutic purposes. People can often have similar manifestations of disease, but no two patients will be the same. Functional radionuclide imaging and positron emission tomography (PET) provide excellent opportunities to follow the pathology in individual patients and therefore provide a means for tailored clinical management. These also provide the means to assess the response to treatment in a safe and non-invasive manner. Changes at molecular and cellular levels provide vital clues for evaluating the effectiveness of chosen clinical treatment plans. This information is expected to have a major impact on understanding disease, disease detection, individualised treatment, and drug development. Recently, considerable attention has been drawn to nuclear medicine with the visualization of biochemical processes in vivo such as PET studies with 18F-FDG in many different organs and in cancerous tissues. With the arrival of PET/CT systems there is a new era of accurate mapping of disease processes. Today, 18F-FDG is the most useful PET tracer for the detection, staging, treatment planning and management of cancer. There is mounting evidence for its competitive advantage over conventional techniques in major medical areas including oncology, cardiology, and neurology. Nuclear medicine is

    From May 25 to 30, 2003 the beautiful city of Cancun, located in the heart of the ancient Maya Empire in Mexico, hosted the XIX ALASBIMN CONGRESS. More than 300 attendees and 80 lecturers from the American continent and Europe had the opportunity to share their knowledge and enjoy an outstanding scientific, cultural and social program. The Scientific program included reviews and original scientific papers on basic and clinical sciences as well as on new developments in diagnostic and therapeutic nuclear medicine. Cardio-vascular, neuropsychiatric, oncology, skeletal and paediatric procedures were comprehensively analysed by several experts. Introduction of new cyclotrons and modern PET and PET/CT systems in Latin America has opened new horizons for the nuclear medicine community in this sub-continent. New radiopharmaceuticals based on different peptides, receptors and gene expression dominated the scene. Reporter gene imaging of gene expression has become the first and best example of what is achievable by modern molecular imaging. Of particular interest was the presentation of novel and potential agents for radio-metabolic therapy. Additionally, in connection with the congress the IAEA organised a very successful Regional Training Course on Paediatric Nuclear Medicine with 23 participants from 11 countries. The Agency also hosted the first national project coordinators meeting of the IAEA Regional Project aimed at establishing a regional tele-nuclear medicine network in the Latin American Region in conjunction with the ALASBIMN meeting. Once again the major companies representing the nuclear medicine industry participated in the Congress and contributed to the success of the ALASBIMN meeting. In summary, attending the XIX ALASBIMN meeting was a very rewarding experience in every aspect. We are most grateful to the organisers for hosting such a nice congress. Congratulations! Now we are looking forward to participate in the next ALASBIMN Congress to be held in the

  20. Thirty year celebration of the contribution of nuclear medicine physicists in Australia

    Full text: The intention of this article is to describe the contributions of the many nuclear medicine physicists who in a large or small way have added to the ongoing development of nuclear medicine in Australia from the first years of the discipline in the late 1960s to the present time. Unlike our colleagues in radiation oncology physics, the nuclear medicine physicist fraternity has always been a very small group which unfortunately has not expanded greatly over the 30 years and beyond. This is emphasized in the survey by W.H.Round 1 which showed the bias towards older physicists being involved in the discipline. Because of the small numbers of nuclear medicine physicists in the public hospital system, mostly one or two per teaching hospital, most physicists are heavily involved in clinical duties to keep up the high standard of equipment and software performance required. Many nuclear medicine physicists also have the dual role of hospital radiation safety officers which is becoming more demanding as radiation legislation increases. For this reason much of the pure research has been confined to the hospitals with larger numbers of physicists. However a high proportion of nuclear medicine physicists across the country have contributed greatly to clinical research and development as part of their job. Unfortunately these cannot all be recognised in this article. Young physicists may not realise how much 'in house' research and development was carried out by physicists in the early years of nuclear medicine when equipment companies did not provide the software which is now available to purchase. Many of these innovative techniques and software, described in this article, are still in use today. Some of the 'big events' in the history of nuclear medicine in Australia in which physicists have played a leading role will also be highlighted. This will serve to emphasize how physicists have worked closely with clinicians and technologists in the ongoing development of
