  1. Evidence and First-Person Authority

    OpenAIRE

    Corbí, Josep E.

    2011-01-01

    In this paper, I challlenge David Finkelstein's claim that evidence does not contribute to first-person authority. To this end, I first argue that the phenomenon of first-person authority involves a certain combination of two kinds of authority, namely: an epistemic (insofar as evidence is at issue here) and a practical (insofar as the capacity to shape one's own psychological and dispositions is the central concern) kind of authority. Secondly, I defend the view that gathering evidence plays...

    A new computer system to produce three dimensional surface image from CT scan has been invented. Although many similar systems have been already developed and reported, they are too expensive to be set up in routine clinical services because most of these systems are based on high power mini-computer systems. According to the opinion that a practical 3D-CT system should be used in daily clinical activities using only a personal computer, we have transplanted the 3D program into a personal computer working in MS-DOS (16-bit, 12 MHz). We added to the program a routine which simulates surgical dissection on the surface image. The time required to produce the surface image ranges from 40 to 90 seconds. To facilitate the simulation, we connected a 3D system with the neuronavigator. The navigator gives the position of the surgical simulation when the surgeon places the navigator tip on the patient's head thus simulating the surgical excision before the real dissection.

    1988-01-01

    In a retrospective analysis of CT scans available from 2,102 neurologically normal persons, dilatations of the cerebellar vermis fissures (CVF), cerebellar hemispheric fissures (CHF), subarachnoid space (SAS) around the cerebellum and the fourth ventricle (FV) were examined according the age groups of persons younger than one year, one to four, five to nine, 10 to 19, 20 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, and 70 years and older. An dilatation of both the CVF and CHF was associated with aging, with statistically significant differences among age groups of persons older than 20 years. This was especially noted in age groups of 60 years or older. There was a significant enlargement in the SAS around the cerebellum in age groups 60 years or more compared with age groups less than 60 years. For age groups of persons 20 years or older, both the FV transverse width and the radio of the FV transverse width to the inside diameter of the posterior fossa (PF) increased with aging. This was significant in age groups 60 years or older. For age groups younger than 10 years, however, there was inverse correlation between the ratio of the FV transverse width to the PF inside diameter and aging. Plotted curve of the ratio of the FV to the PF was U-shaped with smallest value in persons in their twenties. Since changes in the FV might reflect the volume of the cerebellar medullary substance, the cerebellar medullary substance should increase up to the age of 20. (Namekawa, K.)

    Full Text Available Purpose: Reducing unnecessary testing may benefit patients, as some computed tomography (CT and magnetic resonance imaging (MRI expose patients to contrast, and all CTs expose patients to radiation. This observational study with historical controls assessed shifts in CT and MRI utilization over a 9-year period after a private health insurer’s implementation of a nondenial, consultative prior authorization program. Methods/Materials: Normalized rates of exams per 1000 person-years were plotted over 2005 to 2014 for people with commercial and Medicare Advantage health plans in the San Antonio market, with 2005 utilization set as the baseline. The program was implemented at the start of 2006. Computed tomography and MRI utilization changes were compared with contemporaneous changes in low-tech plain film and ultrasound utilization. Results: Growth in high-tech imaging utilization decelerated or reversed during the period. In 2006, CT utilization dropped to between 76% and 90% of what it had been in 2005, depending on the plan. In 2014, it was between 52% and 88% of its initial level. MRI utilization declined to between 86% and 94% of its initial level in 2006, and then to between 50% and 75% in 2014. Ultrasound utilization was greater in 2014 than in 2005 for some plans. Plain film utilization declined between 2005 and 2014 for all plans. Conclusion: There was an immediate and sustained decline in CT and MRI utilization after the introduction of the program. While many factors may have impacted the long-term trends, the mixed trends in low-tech imaging suggest that a decline in low-tech imaging was not responsible for the decline in CT and MRI utilization.

    The theory of radiation carcinogenesis has been debated for decades. Most estimates of the radiation risks from CT have been based on extrapolations from the lifespan follow-up study of atomic bomb survivors and on follow-up studies after therapeutic radiation, using the linear no-threshold theory. Based on this, many population-based projections of induction of future cancers by CT have been published that should not be used to estimate the risk to an individual because of their large margin of error. This has changed recently with the publication of three large international cohort follow-up studies, which link observed cancers to CT scans received in childhood. A fourth ongoing multi-country study in Europe is expected to have enough statistical power to address the limitations of the prior studies. The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) report released in 2013 specifically addresses variability in response of the pediatric population exposed to ionizing radiation. Most authorities now conclude that there is enough evidence to link future cancers to the radiation exposure from a single CT scan in childhood but that cancer risk estimates for individuals must be based on the specifics of exposure, age at exposure and absorbed dose to certain tissues. Generalizations are not appropriate, and the communication of the CT risk to individuals should be conducted within the framework of personalized medicine. (orig.)

    To evaluate the usefulness of the reconstructed 3-dimensional image on the personal computer in comparison with that of the CT workstation by quantitative comparison and analysis. The spiral CT data obtained from 27 persons were transferred from the CT workstation to a personal computer, and they were reconstructed as 3-dimensional image on the personal computer using V-works 2.0 TM . One observer obtained the 14 measurements on the reconstructed 3-dimensional image on both the CT workstation and the personal computer. Paired test was used to evaluate the intraobserver difference and the mean value of the each measurement on the CT workstation and the personal computer. Pearson correlation analysis and % imcongruence were also performed. I-Gn, N-Gn, N-A, N-Ns, B-A and G-Op did not show any statistically significant difference (p>0.05), B-O, B-N, Eu-Eu, Zy-Zy, Biw, D-D, Orbrd R, and L had statistically significant difference (p<0.05), but the mean values of the differences of all measurements were below 2 mm, except for D-D. The value of correlation coefficient γ was greater than 0.95 at I-Gn, N-Gn, N-A, N-Ns, B-A, B-N, G-Op, Eu-Eu, Zy-Zy, and Biw, and it was 0.75 at B-O, 0.78 at D-D, and 0.82 at both Orbrb R and L. The % incongruence was below 4% at I-Gn, N-Gn, N-A, N-Ns, B-A, B-N, G-Op, Eu-Eu, Zy-Zy, and Biw, and 7.18%, 10.78%, 4.97%, 5.89% at B-O, D-D, Orbrb R and L respectively. It can be considered that the utilization of the personal computer has great usefulness in reconstruction of the 3-dimensional image when it comes to the economics, accessibility and convenience, except for thin bones and the landmarks which and difficult to be located

    Full Text Available With improvements in CT technology, the need for reliable patient-specific dosimetry increased in the recent years. The accuracy of Monte-Carlo simulations for absolute dose estimation is related to scanner specific information on the X-ray spectra of the scanner as well as the form filter geometries and compositions. In this work a mobile measurement setup is developed, which allows both to determine the X-ray spectra and equivalent form filter of a specific scanner from just one helical scan in less than 2 minutes.

    Objective: To investigate the feasibility of the low tube voltage setting and personalized contrast agent application in 64-row multi-slice spiral CT pulmonary angiography. Methods: Ninety patients with high risk of pulmonary artery embolism were sequentially enrolled in the study and divided into 3 groups employing completely randomized design: (l)Regular group included 30 patients using 120 kV and fixed dose of 70 ml contrast agent, (2)Another 30 patients were in 120 kV group, using 120 kV and the contrast amount was determined according to the patient weight (1.0 ml/kg), (3) The remaining 30 patients were included in 100 kV group, using 100 kV and the contrast amount was also determined according to the patient weight(1.0 ml/kg). Administration of contrast agent was completed within 20 seconds for all the patients, followed by 20 ml of saline. The objective and subjective indexes for assessing CT image quality, CT dose index volume (CTDIvol) and effective received dose (ERD) were compared between 120 kV group and 100 kV group; then the contrast media volume, injection rate, objective CT image indexes and subjective indexes for image quality was compared between the 100 kV group and regular group. The variance analysis and post hoc test were employed for the statistical analysis. Results: Compared with 120 kV group (3.4±0.7), the image quality of 100 kV group (5.2±1.8) had higher noise (52.9%), but subjective index for the image quality demonstrated no differences (q=0.272, P=0.063) in mediastinum window while CTDIvol and ERD decreased for 34.9% [(9.5±0.0) vs (14.6±0.0) mGy] and 36.8% [(3.8±0.6) vs (2.4±0.4) mSv]. The mean CT values on pulmonary artery of 100 kV group[ (269.2±54.7) HU] were 13.4% (31.8/237.4) higher than the 120 kV group [(237.4±62.9)HU], but there was no statistical differences compared to normal group (q=0.172,P=0.260). Conclusion: Using low kV setting (100 kV) to reduce radiation dose is proved to be effective and feasible in 64-MSCT

    Patterns of authority beliefs were examined among peer crowds in 598 middle school (M=12.97 years), early high school (M=15.10 years), and late high school adolescents (M=18.25 years). Participants reported beliefs regarding the boundaries of personal authority across personal, prudential, conventional, moral, and multifaceted issues. As expected, analyses revealed persistent differences in belief patterns among crowds within each age group. Tough and Alternative crowds asserted personal authority across all issues, while Prep and Outcast crowds endorsed parental authority. Jock, Hip Hop, and Normal crowds presented with shared-control patterns, but each crowd ceded and asserted authority over different issues. Discussion focused on crowds' roles in the development of group differences in the boundaries of personal authority.

    Objective: To investigate the feasibility of decreasing radiation dose and contrast media dose of abdominal CTA using low tube voltage setting combined with personalized contrast media application. Methods: One hundred and twenty patients were randomly divided into 3 groups, and there were 40 patients in each group. 120 kV tube voltage was used in group A, and 100 kV tube voltage was used in group B and C. Personalized injection flow rate of contrast media which determined according to patient's body mass (injection flow rate =λ × body mass) was used for all groups, and the λ values for group A, B and C were 0.07, 0.07 and 0.06 ml · kg -1 · s -1 respectively. CT dose index volume (CTDIvol) effective dose (ED) and contrast media dose were evaluated,and these parameters were all analyzed using one-way ANOVA analysis. Image quality of abdominal aorta and branch arteries was rated using a three-point ordinal for all 3 groups, and image quality score was analyzed using Kruskal-Wallis test. Results: CTDIvol were (8.2±0.8), (6.0 ±1.0) and (6.1 ±1.1)mGy for group A, B and C, ED were (5.2 ±0.8), (3.5 ± 0.7) and (3.6 ± 0.6) mSv, and contrast media dose were (72.3 ± 10.3),(73.5 ± 11.3) and (61.6 ±9.4) ml, respectively. There were significant differences in CTDIvol, ED and contrast media dose among 3 groups (F=66.094, 77.812,15.919; P=0.000). Compare with group A, the ED of group B was decreased 32.7%, and the ED and contrast media dose of group C were decreased 30.8% and 14.8%, respectively. Image quality was rated as excellent, good, and general for 20, 19 and 1 patients in group A, 25, 15 and 0 patients in group B, and 23, 17 and 0 patients in group C, respectively. There was no significant difference in image quality score among 3 groups (χ 2 =1.492, P=0.474). Conclusions: The radiation dose and contrast media dose can be decreased in abdominal CTA using low tube voltage and personalized contrast media application while image quality can be preserved

    Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. We will report the clinical and radiological findings of our personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. We will also try to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. In the last seven years we retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different causes. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the mid-chest for accurate assessment of diaphragm and lung bases and to exclude associated pleuropulmonary damage. Penetrating liver wounds were caused by firearms in 70% of cases, by stabbing in 12% and, in the extant 18%, by other causes such as home accidents, road and work traumas, and liver biopsy. In our series, the liver was most frequently involved, especially by firearms wounds; in our 16 cases the most frequent injuries were hemorrhagic tears. We found bullets in the liver in 6 cases. In one case of home accident the patient wounded himself while slicing bread with a long knife, which cut into the anterior abdominal wall and tore the anterior liver capsule, as seen at CTA. Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of the extent and

    The last 40 years Monte Carlo (MC) simulations serve as a “gold standard” tool for a wide range of applications in the field of medical physics and tend to be essential in daily clinical practice. Regarding diagnostic imaging applications, such as computed tomography (CT), the assessment of deposited energy is of high interest, so as to better analyze the risks and the benefits of the procedure. The last few years a big effort is done towards personalized dosimetry, especially in pediatric applications. In the present study the GATE toolkit was used and computational pediatric phantoms have been modeled for the assessment of CT examinations dosimetry. The pediatric models used come from the XCAT and IT'IS series. The X-ray spectrum of a Brightspeed CT scanner was simulated and validated with experimental data. Specifically, a DCT-10 ionization chamber was irradiated twice using 120 kVp with 100 mAs and 200 mAs, for 1 sec in 1 central axial slice (thickness = 10mm). The absorbed dose was measured in air resulting in differences lower than 4% between the experimental and simulated data. The simulations were acquired using ∼10 10 number of primaries in order to achieve low statistical uncertainties. Dose maps were also saved for quantification of the absorbed dose in several children critical organs during CT acquisition. (paper)

    The purpose of this study was to report the reproducibility of intra-observer and inter-observer consistency of cephalometric measurements using three-dimensional (3D) computed tomography (CT), and the degree of difference of the cephalometric measurements. CT images of 16 adult patients with normal class I occlusion were sent to personal computer and reconstructed into 3D images using V-Works 3.5{sup TM} (Cybermed Inc., Seoul, Korea). With the internal program of V-Works 3.5{sup TM}, 12 landmarks on regular cephalograms were transformed into 21 analytic categories and measured by 2 observers and in addition, one of the observers repeated their measurements. Intra-observer difference was calculated using paired t-test, and inter-observer by two sample test. There were significant differences in the intra-observer measurements (p<0.05) in four of the categories which included ANS-Me, ANS-PNS, Cdl-GO (Lt), GoL-GoR, but with the exception of Cdl-Go (Lt), ZmL-ZmR, Zyo-Zyo, the average differences were within 2 mm of each other. The inter-observer observations also showed significant differences in the measurements of the ZmL-ZmR and Zyo-Zyo categories (p<0.05). With the exception of the Cdl-Me (Rt), ZmL-ZmR, Zyo-Zyo categories, the average differences between the two observers were within 2mm, but the ZmL-ZmR and Zyo-Zyo values differed greatly with values of 8.10 and 19.8 mm respectively. In general, 3D CT images showed greater accuracy and reproducibility, with the exception of suture areas such as Zm and Zyo, than regular cephalograms in orthodontic measurement, showing differences of less than 2 mm, therefore 3D CT images can be useful in cephalometric measurements and treatment planning.

    Full Text Available Traditional Author Cocitation Analysis was applied in order to map the personality psychology as a research field. A group of 25 authors were selected from the Haggbloom (1999, 2002 lists of the most cited and prominent psychologists, judged to be the main contributors to the field. All of their cocitations identified in the three year volumes of SSCI were downloaded to be analyzed by cluster analysis and MDS. The analysis resulted in four clusters comprising (1 theorists of individual differences amalgamated with authors of biological orientation with R. Cattell positioned centrally, (2 behaviorists joined by socio-cognitive theorists led by M.E.P. Seligman and A. Bandura, and (3 the group of psychoanalytic (dynamic theorists with A. Adler in the middle. In fourth cluster G. Allport, H. Murray, K. Lewin, W. Mischel, and D. Buss were found mixed together to make a rather heterogeneous group. In two-axes representation one of the dimensions was understood as reflecting methodological and the other one content-specific differences among the authors, although this interpretation is not univocal. The same procedure was repeated on citations given to the same authors in SocioFakt - the Serbian Citation Index for Social Sciences, revealing a reduced picture of the domain. At this portrait, some important authors are missing as a result of their low citation rate, suggesting that in the Serbian personality psychology entire research fields don’t exist. .

    This investigation was made on the INIS database produced in 1981 and original papers concerned. Its analysis revealed a significant difference of descriptions of the names between inputs from the INIS center for Japan and inputs from other INIS national centers to INIS. The percentage that the former center spelled out was 92%. However, 99.9% of the items from the latter centers had only one initial of given name, though 45% of the items had fully-spelled given names in the original papers. This investigation was supplemented by check of samples of Japanese name in other databases i.e., CA Search, NTIS, COMPENDEX and INSPEC. In conclusion, it is required to spell out Japanese personal author's names in Roman character to all of authors, editors of primary documents and producers of secondary information databases in English, in order to obtain high identification of the names.

    In order to personalize the communication of the CT risk, we need to describe the risk in the context of the clinical benefit of CT, which will generally be much higher, provided a CT scan has a well-established clinical indication. However as pediatric radiologists we should be careful not to overstate the benefit of CT, being aware that medico-legal pressures and the realities of health care economics have led to overutilization of the technology. And even though we should not use previously accumulated radiation dose to a child as an argument against conducting a clinically indicated scan (the ''sunk-cost'' bias), we should consider patients' radiation history in the diagnostic decision process. As a contribution to future public health, it makes more sense to look for non-radiating alternatives to CT in the much larger group of basically healthy children who are receiving occasional scans for widely prevalent conditions such as appendicitis and trauma than to attempt lowering CT use in the smaller group of patients with chronic conditions with a limited life expectancy. When communicating the CT risk with individual patients and their parents, we should acknowledge and address their concerns within the framework of informed decision-making. When appropriate, we may express the individual radiation risk, based on estimates of summated absorbed organ dose, as an order of magnitude rather than as an absolute number, and compare this with the much larger natural cancer incidence over a child's lifetime, and with other risks in medicine and daily life. We should anticipate that many patients cannot make informed decisions on their own in this complex matter, and we should offer our guidance while maintaining respect for patient autonomy. Proper documentation of the informed decision process is important for future reference. In concert with our referring physicians, pediatric radiologists are well-equipped to tackle the complexities

When communicating the CT risk with individual patients and their parents, we should acknowledge and address their concerns within the framework of informed decision-making. When appropriate, we may express the individual radiation risk, based on estimates of summated absorbed organ dose, as an order of magnitude rather than as an absolute number, and compare this with the much larger natural cancer incidence over a child's lifetime, and with other risks in medicine and daily life. We should anticipate that many patients cannot make informed decisions on their own in this complex matter, and we should offer our guidance while maintaining respect for patient autonomy. Proper documentation of the informed decision process is important for future reference. In concert with our referring physicians, pediatric radiologists are well-equipped to tackle the complexities associated with the communication

    There are two wrong opinions on personal right of an author :one insists on that personal right of an author is the right of identity ,the other considers it as property right .The former view only sees the phenomenon of personal right of an author but ignores its essence ,and the latter view misunder-stands its essential characteristic .It is arguable that personal right of an author is a special social personal right w hich shouldn't be merged into the personal right of civil law ,and that personal right of an author should adhere to its primary meaning and be improved in details .%认为著作人身权是身份权的观点,只看到现象而忽视了著作人身权本质;认为著作人身权是财产权的观点,是对人格权的本质属性存在误解,没有看到社会人格权能够转让的属性。著作人身权是特殊的人格权,取缔或者合并到民法中的人格权中都是不可取的,而应该在现有基础上对著作人身权的内容加以完善。

    Full Text Available Authorized Persons (AP play a critical role in the design and construction of building works in Hong Kong. Under the Building Ordinance, design and construction of building works need to be coordinated and monitored by an AP registered with the Buildings Department. Professionally qualified Architects, Engineers and Surveyors are eligible to register as AP after completing the prescribed assessment. In addition, the project AP is often appointed by the project owner to be the project team leader. In these capacities, a project AP is exposed to various risks. This paper seeks to identify the fee sensitive risk exposures of project APs. Through an ANOVA study, these risks exposures are those due to liabilities under the Building Ordinance at the construction stage, those towards the third parties and the clients.

    The advantage of CT scans in muscular pathology is studied. The scan, in addition to the diagnosis of tumors and muscular abscesses, permits to differentiate primary myopathies from neurogenic atrophies: in the course of myopathies, the muscle volume is preserved and they appear as a hypodensity; in neurogenic atrophies, the muscle volume is reduced with preserved density. The CT scan permits to determine the extension of these lesions. In the course of polymyositis, certain forms of rheumatid arthritis, the scan discloses a trabecular and 'worm-eaten' aspect of the muscles. This is also observed after long-term steroid therapy and other endocrine diseases (hyperthyroidism, osteomalacia) indicating an infra-clinical myopathy. In vertebral osteoporosis with fractures and patients with chronic lumbalgia, very ofter, an atrophy of the spinal muscle is observed.

  13. Use of the EC quality criteria as a common method of inspecting CT laboratories - A pilot project by the Nordic radiation protection authorities

    Torp, C.G.; Olerud, H.M.; Einarsson, G.; Groen, P.; Leitz, W.; Servomaa, A.

    2001-01-01

    In the frame of Nordic radiation protection co-operation, quality criteria for computed tomography (CT) as published by the European Commission were used for the evaluation of selected CT laboratories in each of the Nordic countries. The mean values for all five countries of the weighted CT dose index (CTDI w ) and dose length product (DLP) were 60 mGy and 740 mGy · cm for CT of the brain, 11 mGy and 420 mGy · cm for CT of the chest, and 40 mGy and 420 mGy · cm for CT of the lumbar spine, respectively. A comparison with the reference levels set in the above mentioned publication gives a diversified result: compliance for the DLP-values is generally achieved with good margins whereas the CTDI w -values were frequently larger for brain and lumbar spine examinations. The radiographic technique was generally also within the recommendations from the EC. Generally most of the image quality criteria were fulfilled, but it must be borne in mind that the study was biased in the way that two local radiologists in consensus evaluated their own images. Image material from only three patients was selected for each of the clinical indications, that means the project was not designed for ranking laboratories, but it is a way of making the departments aware of the need for optimisation regarding image quality and patient dose, and also of the problems associated with this task. During the study suggestions were brought forward concerning amendments of the quality criteria: some need a better definition, some are not relevant for the diagnostic task in question, some could be added. Instead of 'yes' and 'no', a range of maybe 5 levels of visualisation should be introduced in order to better characterize the level of diagnostic performance. (author)

    2016-03-01

    This study outlines a theory of social class based on workplace ownership and authority relations, and it investigates the link between social class and growth in personal income inequality since the 1980s. Inequality trends are governed by changes in between-class income differences, changes in the relative size of different classes, and changes in within-class income dispersion. Data from the General Social Survey are used to investigate each of these changes in turn and to evaluate their impact on growth in inequality at the population level. Results indicate that between-class income differences grew by about 60% since the 1980s and that the relative size of different classes remained fairly stable. A formal decomposition analysis indicates that changes in the relative size of different social classes had a small dampening effect and that growth in between-class income differences had a large inflationary effect on trends in personal income inequality.

    Trauma is the third leading cause of death, irrespective of age, and the leading cause of death in persons under 40 persons under 40 years of age. Most pleural, pulmonary, mediastinal, and diaphragmatic injuries are not seen on conventional chest radiographs, or are underestimated. In patients with chest trauma, CT scanning is an effective and sensitive method of detecting thoracic injuries and provides accurate information regarding their pattern and extent.

    Becquemont, Laurent; Bordet, Régis; Cellier, Dominic

    2012-01-01

    One of the challenges of the coming years is to personalize medicine in order to provide each patient with an individualized treatment plan. The three objectives of personalized medicine are to refine diagnosis, rationalize treatment and engage patients in a preventive approach. Personalization can be characterized by various descriptors whether related to the field, biology, imaging, type of lesion of the entity to be treated, comorbidity factors, coprescriptions or the environment As part of personalized medicine focused on biological markers including genetics or genomics, the integration of the clinical development plan to obtain marketing authorization may be segmented in 3 stages with a known descriptor identified before clinical development, a known descriptor discovered during clinical development or a known descriptor known after clinical development. For each stage, it is important to clearly define the technical optimization elements, to specify the expectations and objectives, to examine the methodological aspects of each clinical development phase and finally to consider the fast changing regulatory requirements in view of the few registered therapeutics complying with the definition of personalized medicine as well as the significant technological breakthroughs according to the screened and selected biomarkers. These considerations should be integrated in view of the time required for clinical development from early phase to MA, i.e. more than 10 years. Moreover, business models related to the economic environment should be taken into account when deciding whether or not to retain a biomarker allowing the selection of target populations in a general population. © 2012 Société Française de Pharmacologie et de Thérapeutique.

    The acronym THERANOSTICS epitomizes the inseparability of diagnosis and therapy, the pillars of medicine and takes into account personalized management of disease for a specific patient. Molecular phenotypes of neoplasms can be determined by molecular imaging with specific probes using positron emission tomography (PET), single photon emission computed tomography (SPECT), magnetic resonance imaging (MRI), or optical methods, so that the treatment is specifically targeted against the tumor and its environment. To meet these demands, we need to define the targets, ligands, coupling and labeling chemistry, the most appropriate radionuclides, biodistribution modifiers, and finally select the right patients for the personalized treatment. THERANOSTICS of neuroendocrine tumors (NETs) using Ga-68 labeled tracers for diagnostics with positron emission tomography/ computed tomography (PET/CT), and using Lu-177 or other metallic radionuclides for radionuclide therapy by applying the same peptide proves that personalized radionuclide therapy today is already a fact and not a fiction.

    This study retrospectively analyzed the mean glandular dose (MGD) to 133 breasts from 132 subjects, all women, who participated in a clinical trial evaluating dedicated breast CT in a diagnostic population. The clinical trial was conducted in adherence to a protocol approved by institutional review boards and the study participants provided written informed consent. Individual estimates of MGD to each breast from dedicated breast CT was obtained by combining x-ray beam characteristics with estimates of breast dimensions and fibroglandular fraction from volumetric breast CT images, and using normalized glandular dose coefficients. For each study participant and for the breast corresponding to that imaged with breast CT, an estimate of the MGD from diagnostic mammography (including supplemental views) was obtained from the DICOM image headers for comparison. This estimate uses normalized glandular dose coefficients corresponding to a breast with 50% fibroglandular weight fraction. The median fibroglandular weight fraction for the study cohort determined from volumetric breast CT images was 15%. Hence, the MGD from diagnostic mammography was corrected to be representative of the study cohort. Individualized estimates of MGD from breast CT ranged from 5.7 to 27.8 mGy. Corresponding to the breasts imaged with breast CT, the MGD from diagnostic mammography ranged from 2.6 to 31.6 mGy. The mean (± inter-breast SD) and the median MGD (mGy) from dedicated breast CT exam were 13.9 ± 4.6 and 12.6, respectively. For the corresponding breasts, the mean (± inter-breast SD) and the median MGD (mGy) from diagnostic mammography were 12.4 ± 6.3 and 11.1, respectively. Statistical analysis indicated that at the 0.05 level, the distributions of MGD from dedicated breast CT and diagnostic mammography were significantly different (Wilcoxon signed ranks test, p = 0.007). While the interquartile range and the range (maximum–minimum) of MGD from dedicated breast CT was lower than

    The Positron Emission Tomography-Computed Tomography (PET-CT), in the last years has demonstrated to be an image technique very effective for the diagnosis and the treatments continuation in different medical applications, because provides a valuable clinical information for the patient handling. The PET-CT is a technology used in the nuclear medicine for diagnostic, because integrates two different image techniques in an only device and in a single exam or study combine the results of both techniques. Also, is a hybrid tomograph that provides in a single image the biochemical information of a technique and the anatomical information of the other, what means that unifies the spatial resolution of a technique and the contrast resolution of the other, allowing this way to obtain a more precise and detailed diagnostic information, opening new opportunities in diagnostic, Radiotherapy planning and treatments continuation to the patients, being generated new links among the different radiological medical specialties. In nuclear medicine facilities with PET-CT, the radiological protection presents particular characteristics, due to the photons coexistence of 511 keV (generated by the annihilation of the emitted positrons from the different exposure sources) together to the X-rays emitted by the CT, what impacts in a direct way in those design requirements of the areas. On the other hand, this combination of the two image techniques imposes additional requirements to the learning and training of personnel, not considered until the present time. In this article are exposed the general principles that should be considered in the design of a Nuclear Medicine Area with PET-CT, and the existent problems related to the learning and training of personnel to assume this new technology are also approached.

    Early diagnosis and staging of non-Hodgkin lymphoma (NHL) is essential for therapeutic strategy decision. Positron emission tomography/computed tomography (PET/CT) with fluorodeoxyglucose (FDG), a glucose analogue, labeled with fluor-18 ({sup 18F}-FDG) has been used to evaluate staging, therapy response and prognosis in NHL patients. However, in some cases, {sup 18F}-FDG has shown false- -positive uptake due to inflammatory reaction after chemo and/or radiation therapy. In this case report, we present a NHL patient evaluated with {sup 18F}-FDG and {sup 18F}-choline PET/CT scan imaging pre- and post-therapy. {sup 18F}-FDG and {sup 18F}-choline PET/CT were performed for the purpose of tumor staging and have shown intense uptake in infiltrative tissue as well as in the lymph node, but with some mismatching in the tumor. Post-treatment {sup 18F}-FDG and {sup 18F}-choline PET/ CT scans revealed no signs of radiotracer uptake, suggesting complete remission of the tumor. {sup 18F}-choline may be a complimentary tool for staging and assessment of therapeutic response in non-Hodgkin lymphoma, while non-{sup 18F}-FDG tracer can be used for targeted therapy and patient management.

    Processing of CT images was attempted by using a popular personal computer. The program for image-processing was made with C compiler. The original images, acquired with CT scanner (TCT-60A, Toshiba), were transferred to the computer by 8-inch flexible diskette. Many fundamental image-processing, such as displaying image to the monitor, calculating CT value and drawing the profile curve. The result showed that a popular personal computer had ability to process CT images. It seemed that 8-inch flexible diskette was still useful medium of transferring image data. (author)

  12. Modern imaging for pancreatitis, CT findings versus clinic

    The pancreas with all its diseases is radiologically examined with different methods. The most important ones are CT, MRI, ERCP and ultrasound. I would like to mention here that the diagnosis by ultrasound depends a lot on the person carrying out the examination but due to the availability it is preferably used as the first examination technique. Due to this fact the examination by ultrasound is only referred to quickly in this thesis. More emphasis is put on the different methods of examining certain diseases of the pancreas by CT and MRI. Due to the development of MRI devices which enable a better contrast of the soft tissue than the CT the CT has been pushed back. But also the CT has been developed rapidly that is why it is usually used as the method of choice. Most pancreas diseases can be distinguished well by CT and MRI. (author) [de

    Otosclerosis (otospongiosis) is a primary focal disease of the labyrinthine capsule. The stapes footplate is fixed when the spongiotic focus expands and invades the oval window. Persons with stapedial otosclerosis experience a progressive conductive hearing loss. In many cases, cochlear degeneration is observed, in which a mixed hearing loss occurs. Using computed tomography (CT), the authors studied the ears of 45 selected patients with conductive or mixed hearing loss. CT proved valuable in determining otosclerotic changes of the oval window and otic capsule. Spongiotic changes of the otic capsule are better appreciated by CT than complex motion tomography. The usefulness of CT in diagnosing other causes of conductive or mixed hearing loss is also described

    This work was supported, on the one hand, in a part of the project ORAMED which consisted of a design of a TLD dosimeter for measurements of Hp (3) in areas close to the lens, for interventional radiology physicians. On the other hand, Berhens work proposes using calibrated TLDs Hp (0.07) and Hp (10) to estimate Hp (3) crystal. This resulted in dosimeters calibrated using Hp (10) slab, and mount them on glasses, to estimate the dose to the lens of the technical staff of the Service PET / CT. The value obtained 29mSv/year of Lens Dose Equivalent exceeds the recommended limit. We also demonstrate that, under the current working conditions, the values of Hp (3) reported from whole body dosimeter does not represent faithfully the lens dose.

    The objective of this study was to evaluate the value of CT scan for the detection of tuberculous diseases among persons who are suspected to be infected at the contact examination. The settings of this study was to Fukujuji Hospital, Japan. Retrospective review of the medical records of 22 persons who were normal with plain chest X-ray at an outbreak at a private school, with which total 46 tuberculosis (TB) cases and 93 infected persons were detected by either symptomatic visits or contact examinations done mainly at public health centers. Among the 44 persons who visited Fukujuji Hospital, 4 persons were symptomatic visits, 3 persons were detected as TB cases by the contact examination at public health centers and 3 persons visited Fukujuji Hospital for the purpose of contact examination before examinations at the public health centers. Eight of these 10 persons were with abnormal chest plain X-ray findings and the remaining two persons were normal with plain chest X-ray findings (group A). Among the 34 persons who were referred to Fukujuji Hospital from public health centers as the infected person without diseases, one person showed abnormal chest plain X-ray and 33 persons showed normal chest plain X-ray (group B). Group A persons were examined in June and Group B persons were examined in July. The 2 persons in the group A were with abnormal CT findings. They were not diagnosed as TB by the CT findings but followed up after sputum examinations. Both of them were diagnosed as TB by the positive TB culture. Among the 33 persons in the group B, 20 persons were tested with CT scan at the examination done before starting treatment of latent tuberuclous infection and six of these 20 persons were with abnormal findings and were judged as TB diseases. In the case of outbreak with many TB cases and infected persons, CT should be considered for the detection of TB cases among contacts. (author)

    Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. In this report are examined the clinical and radiological findings of personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. It will also tried to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. In the last seven years it was retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different cases. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the mid-chest for accurate assessment of diaphragm and lung bases and to exclude associated pleuropulmonary damage. Penetrating liver wounds were caused by firearms in 70% of cases, by stabbing in 12% and, in the extant 18%, by other cases such as home accidents, road and work traumas, and liver biopsy. In this series, the liver was most frequently involved, especially by firearms wounds; in the 16 cases the most frequent injuries were hemorrhagic tears. It was found bullets in the liver in 6 cases. In one case of home accident the patient wounded himself while slicing bread with a long knife, which cut into the anterior abdominal wall and tore the anterior liver capsule, as seen at CTA. Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of

    Full Text Available Abstract Background A number of diagnostic tests are required for the detection and management of cancer. Most imaging modalities such as computerized tomography (CT are anatomical. However, positron emission tomography (PET is a functional diagnostic imaging technique using compounds labelled with positron-emitting radioisotopes to measure cell metabolism. It has been a useful tool in studying soft tissues such as the brain, cardiovascular system, and cancer. The aim of this systematic review is to critically summarize the health economic evidence of oncologic PET in the literature. Methods Eight electronic databases were searched from 2005 until February 2010 to identify economic evaluation studies not included in previous Health Technology Assessment (HTA reports. Only full health economic evaluations in English, French, or German were considered for inclusion. Economic evaluations were appraised using published quality criteria for assessing the quality of decision-analytic models. Given the variety of methods used in the health economic evaluations, the economic evidence has been summarized in qualitative form. Results From this new search, 14 publications were identified that met the inclusion criteria. All publications were decision-analytic models and evaluated PET using Fluorodeoxyglucose F18 (FDG-PET. Eight publications were cost-effectiveness analyses; six were cost-utility analyses. The studies were from Australia, Belgium, Canada, France, Italy, Taiwan, Japan, the Netherlands, the United Kingdom, and the United States. In the base case analyses of these studies, cost-effectiveness results ranged from dominated to dominant. The methodology of the economic evaluations was of varying quality. Cost-effectiveness was primarily influenced by the cost of PET, the specificity of PET, and the risk of malignancy. Conclusions Owing to improved care and less exposure to ineffective treatments, personalized medicine using PET may be cost

    This paper evaluates the usefulness of CT for the diagnosis of traumatic laryngotracheal abnormalities. The authors retrospectively evaluated the neck CT studies of 50 patients (36 males, 14 females; age range, 16-75 years) who presented to a level I trauma center after suffering a blunt or penetrating laryngotracheal injury. CT results were correlated with endoscopic or surgical findings in 43 cases. Three groups emerge. CT positive: hyloid bone or laryngotracheal cartilage injury; CT positive: soft-tissue injury only; and CT negative. In group 1, CT demonstrated all bony or cartilaginous injuries proved at surgery or suggested at endoscopy. CT failed to demonstrate laryngotracheal separation in 1 case. In group 2, CT demonstrated all soft-tissue injuries suggested at endoscopy. In group 3, CT findings agreed with those of endoscopy in 7 cases, but minor soft-tissue findings seen at endoscopy were missed in 3 cases. Seven patients were studied only with CT. Ct is an accurate technique for detecting bony or cartilaginous laryngotracheal traumatic abnormalities. However, laryngotracheal separation and minor soft-tissue injuries can be missed

  4. When Fairness Clashes with Personal Autonomy and Parental Authority: A Comparison of Daughters' and Mothers' Reasoning in Two Cultural Contexts in Turkey.

    2017-01-01

    The author examined religious and secular daughters' and mothers' reasoning about personal autonomy, maternal authority, and moral concepts in family decision-making situations in urban Turkey. Sixty-eight daughters and 34 mothers were individually interviewed about decision-making autonomy in general issues and hypothetical daughter-mother conflicts. Results indicated participants regardless of their family status and religious background assigned more decision-making autonomy to mothers when evaluating general issues. Analysis of controversial issues as hypothetical conflicts indicated that daughters and mothers do not hold unitary social judgments about the social world that were always consistent with the norms of their community and family status. There were some religious background differences in evaluations of some conflict stories as a function of whether they evaluated the choices as moral, conventional, personal, and prudential matters. Although secular and religious participants conceptualized daughters and mothers in relational terms rather than characterizing the relations and social issues by harmony, obedience to authority, and acceptance of norms findings suggested that secular women evaluated the hypothetical adolescent-mother conflicts more consistently when the issue entails violation of a moral principle such as justice, fairness, and well-being of the other.

  5. A clinical case of the schizophrenia-like organic personality syndrome after neck hanging with special reference to the brain positron CT showing the lowered functioning in frontal lobe

    A 21-year-old woman developed schizophrenia-like organic personality syndrome subsequent to neck hanging. Brain positron CT with 11 CO, 15 O 2 , and C 15 O 2 showed decreased blood flow in the frontal lobe, decreased glucose metabolism in the frontal and lateral lobes, decreased cerebral metabolic rate of oxygen, and decreased cerebral blood flow, suggesting lowered functioning in the frontal lobe. Since these CT findings were very similar to those in patients with chronic sphizophrenia, clinical symptoms of sphizophrenia seems to be related to lowered functioning in the frontal lobe.

    Two cases of osteogenesis imperfecta found in one family (father and daughter) are reported, and the CT findings are described. Case 1 is a 58-year-old man who fell and struck his head at home on November 10, 1984. He was transferred to Omuta City Hospital when he became semicomatose and decerebrate posturing was noted. His family history revealed 8 persons with osteogenesis imperfecta. A skull X-ray film showed a large skull vault, many wormian bones at the lambdoid suture, platybasia, and a basilar impression. A CT scan demonstrated a right acute subdural hematoma, while the bone image showed well-developed mastoid air cells and a skull deformity characteristic of osteogenesis imperfecta. He had an emergency operation, and a 170-gr clot was successfully evacuated. A postoperative CT scan demonstrated brain atrophy, possibly present before head trauma. Case 2 is the daughter of Case 1 (a 27-year-old woman). She also showed characteristic neuroradiological manifestations on a plain skull film and on a CT scan. A basilar impression and platybasia were also demonstrated. In this report, the possible mechanism of the production of a traumatic acute subdural hematoma is also discussed. (author)

    A nationwide survey in 1995 among Personal Dosimetry Services, authorized by the Spanish Nuclear Safety Council (CSN), has led the Spanish Dosimetry Laboratories to review and update the dosimetric conversion coefficients and correction factors in use in Spain since 1987. The recommendations of the ICRU Report 47(1992) are discussed and adopted. In addition differences in back-scattering form IRCU tissue and PMMA phantoms are analysed. Analytical functions used to calculate conversion coefficients and back-scattering correction factors due to the use of different phantom materials are presented, together with the adopted final values. Firstly, the above mentioned parameters are applied to ISO narrow spectra series, which are discribed in this report. Secondly, differences between 1995 and 1987 values are also shown. (Author)

    PTC or ERCP findings of four cases of Mirizzi syndrome were demonstrated. They consisted of a smooth stricture of the common hepatic duct, curved impressions of the duct and dilatation of proximal biliary radicles. CT could visualize the impacted stone in the neck of the gallbladder, dilatation of proximal common hepatic and intrahepatic duct. Absence of the dilatation of distal common bile duct could also be confirmed by CT, thus the diagnosis of Mirizzi syndrome might be possible by CT. (author)

    The authors report the personal techniques and the results of CT-guided percutaneous drainage of postoperative abdominal fluid collections. CT-guided percutaneous drainage offers many advantages over surgery: it is less invasive, can be repeated and requires no anesthesia, there are not surgery-related risks and lower morbidity and mortality rates. Moreover, subsequent hospitalization is shorter and costs are consequently reduced. The authors conclude that CT-guided percutaneous drainage is the method of choice in the treatment of postoperative abdominal fluid collections [it

    In this paper we present an overview of CT-Urography. With the advent of multislice CT scanners and the evolution of image processing methods this technique now affords optimal urographic images comparable to those obtained with conventional techniques. We describe the acquisition techniques and protocols used by the various authors. Effective radiation dose has conditioned the use of CT-Urography so that the tendency today is to reduce the number of scans by performing, after the non enhanced scan, a single contrast-enhanced scan comprising both the nephrographic and urographic phase. With the use of multislice CT the quality of the urogram improves with the number of slices. We illustrate a variety of processing techniques, multiplanar reconstruction (MPR), maximum (MIP) and average intensity projection (AIP) and volume rendering (VR) and present a series of upper urinary tract tumours testifying to the superiority of the AIP technique over MIP. We then review the results of comparative studies of CT-Urography with conventional urography in upper urinary tract diagnostics. Finally, we describe the advantages and limitations of CT-Urography. [Italian] Gli Autori presentano una panoramica sulla Urografia TC (Uro TC). L'avvento della TC multistrato e l'evoluzione delle tecniche di elaborazione consentono di ottenere dei quadri urografici ottimali comparativi con quelli convenzionali. Vengono ricordate le varie tecniche di acquisizione e i protocolli usati dai vari Autori. La dose effettiva di radiazioni ha rappresentato uno dei fattori condizionanti per cui oggi prevale l'orientamento di ridurre il numero di scansioni, considerando dopo la scansione senza mezzo di contrasto un'unica scansione contrasto grafica comprendente sia la fase nefrografica che quella urografica. Con l'uso della TC multistrato la qualita dell'urogramma migliora con l'aumento del numero degli strati. Vengono descritte le varie tecniche di elaborazione, la

    1999-11-01

    SmartPrep is software program for scanning a given region of interest (ROI) at optimal contrast density. An operator can arbitrarily define ROI and preset the CT value at which scanning should be started. After the injection of a contrast medium, system conducts continuous monitoring of the ROI and the operator starts helical scanning of the planned region when the present CT value has been reached. In comparison with conventional helical CT that requires a period of time from the beginning of contrast medium injection to the beginning of scanning, SmartPrep minimizes personal error and better depicts the artery-predominant phase under optimal conditions. In this study we examine the usefulness of contrast-enhanced helical CT using SmartPrep in the evaluation of gynecological disease. When the contrast medium was injected into the dorsal vein of the hand at a rate of 3 ml/sec, strong staining of pelvic arteries was observed in the CT images started at 17 to 23 sec after injection. The early-phase helical CT obtained under these conditions provided good depiction of lesions in cases of placenta accreta and invasive mole, as well as clear demonstration of tumor angiogenesis and evaluation of laterality in cases of cervical cancer. Comparison of the early and delayed phase also facilitated easier evaluation of lymph nodes than conventional comparison of simple and contrast-enhanced CT. The results thus suggest the usefulness of contrast-enhanced helical CT using SmartPrep in gynecology. (author)

  6. Authoring Tools

    Science.gov (United States)

    Treviranus, Jutta

    Authoring tools that are accessible and that enable authors to produce accessible Web content play a critical role in web accessibility. Widespread use of authoring tools that comply to the W3C Authoring Tool Accessibility Guidelines (ATAG) would ensure that even authors who are neither knowledgeable about nor particularly motivated to produce accessible content do so by default. The principles and techniques of ATAG are discussed. Some examples of accessible authoring tools are described including authoring tool content management components such as TinyMCE. Considerations for creating an accessible collaborative environment are also covered. As part of providing accessible content, the debate between system-based personal optimization and one universally accessible site configuration is presented. The issues and potential solutions to address the accessibility crisis presented by the advent of rich internet applications are outlined. This challenge must be met to ensure that a large segment of the population is able to participate in the move toward the web as a two-way communication mechanism.

  7. CT of splenic trauma

    Griffiths, B.G.; Federle, M.P.; Minagi, H.; Jeffrey, R.B.

    1986-01-01

    Fifty-five consecutive cases of surgically proved splenic injuries were evaluated by CT. CT correctly identified 54 splenic injuries, with one false-negative and three false-positive studies. In the single false-negative study and in two of the three false-positive studies, CT correctly indicated the presence of a large hemoperitoneum and other abdominal visceral lacerations and so correctly indicated the need for surgery. Of the 55 proved cases of splenic injury, CT revealed hemoperitoneum in 54 (99%), perisplenic clot in 47 (85%), splenic laceration in 39 (71%), and subcapsular hematoma in 13 (24%). Perisplenic clot can be distinguished from lysed blood in the peritoneal cavity and is a sensitive and specific sign of splenic trauma, even in the absence of visible splenic laceration. The authors conclude that CT is highly reliable means of evaluating splenic trauma

    2006-01-01

    Objective: To study CT findings of hepatic abscess. Methods: CT findings and clinical materials of 38 patients with liver abscess verified by aspiration were retrospectively viewed. All patients were examined by non-enhanced and contrast enhanced CT. Results: In 25 cases, inhomogeneous hypodense lesions with unclear demarcation were found on non-enhanced CT. On contrast enhanced CT scan, target or cluster enhancement was found Additionally, air was found within some lesions. In the rest 13 cases with early stage liver abscess, no typical sign was found on non-enhanced CT, while rosette sign and continued enhancement sign were demonstrated after the contrast agent was given. Conclusion: Various CT findings are found in different stages of liver abscess. The diagnosis and differential diagnosis should be based on CT manifestations and clinical history as well. (authors)

    It is very important for a neurosurgeon to know the consistency of a brain tumor preoperatively, since the information which is of much use in indicating the likely difficulty of the operation, which operative tools should be selected, the amount of bleeding to be expected from the tumor, and so on. The authors, therefore, tried to evaluate the consistency of brain tumors preoperatively 27 cases in which the margin of the tumor was made clear with a homogeneous stain were studied concerning the relationship between the tumor consistency and the CT findings. The results are as follows: 1) A higher CT number on a plain CT indicated a harder consistency of the tumor. 2) A lesser contrast index (CT number on enhancement CT/CT number on plain CT) showed a harder consistency of the tumor.

    2002-01-01

    Few reports have discussed the absorbed dose on CT units with increased scanning capacity even with the current widespread adoption of multi-slice CT units. To compare and investigate the dose indexes among CT units, we measured the absorbed dose on CT units operating in Nagano Prefecture Japan. The measurements showed proportionality between phantom absorbed dose and the exposured mAs values in conventional scanning operation. Further, the measurements showed that the absorbed dose in the center of the phantom differed by about 2.1-fold between the highest and lowest levels on individual CT units. Within a single company, multi-slice CT units of the same company gave absorbed doses of about 1.3 to 1.5 times those of conventional single-slice CT units under the same exposured conditions of conventional scanning. When the scanning pitch was reduced in helical scanning, the absorbed dose at the center of the phantom increased. (author)

    To compare Yen/person saved in lung cancer screening using helical CT with Yen/person in the screening using conventional direct chest X-rays conducted under the Anti-lung cancer association program of the Tokyo Health Service Association. A mathematical model for cancer screening was used to estimate net number of person relieved from lung cancer by the screening and net cost required for the screening. Finally cost-effectiveness ratios in terms of Yen/person saved were calculated and compared between the two programs. Several important variables employed in the model were as follows: 5 year survival rate in chest X-ray group was 50%, and the rate in helical CT group was 75%. Cost of screening in the chest X-ray group was 15,000 Yen, and that in the helical CT group was 25,000 Yen. Cost/person screened was 14,470 Yen for chest X-ray and 21,890 Yen for helical CT. Cost/person saved was 267 x 10 5 Yen in X-ray group and 112 x 10 5 Yen in CT group. Thus the cost was higher, but cost-effectiveness ratio was better in the CT screening group. Helical CT can be adopted for lung cancer screening in stead of chest X-ray if total cost is affordable. (author)

    Twenty-seven cases of small hepatic tumors were examined by MRI and CT (ICT). MRI was more sensitive than plain and contrast CT. But ICT could detect more small lesions than MRI. CT is not more superior modality than MRI untill ICT is performed. It is concluded ICT should be done when diagnosing small hepatic tumors by CT. (author).

  15. CT after transsphenoidal surgery

    Two hundred and ten CT studies of 95 patients after transsphenoidal surgery were reviewed. Spheno-ethmoid opacificaiton, intrasellar hematoma and gas bubbles were noted within 2 weeks after surgery. Bone defect of the sellar floor and bone stent were seen on coronal scans in most cases. The packing material frequently disappeared on follow-up studies. Hormonal assessment of the functioning tumor, according to which the effect of treatment was evaluated, was correlated with CT findings. Because differentiation between postoperative changes and residual mass was difficult, there was no definite CT criteria to indicate residual functioning tumor except upward convexity of the diaphragma sellae on CT more than 3 months after surgery. Initial follow up CT study is recommended to be performed at about 3 months after surgery, at which time the immediate postoperative inflammatory changes have been disappeared. The incidence of recurrence was 3/47 (6%), which was shown on follow-up CT from 4 to 10 years after surgery. Therefore, subsequent CT study should be done in every year or two, taking the clinical symptoms and hormonal data into consideration. (author)

    The objective of this study was to evaluate the efficacy of lung cancer screening by thoracic computed tomography (CT), a randomized controlled trial was planned in Japan. The randomized trial was designed as follows: participants were randomly assigned into 2 groups, CT group and XP group; XP group would receive 10 times of lung cancer screening by chest x-ray annually for 10 years; smokers in CT group would receive 10 times of lung cancer screening by thoracic CT annually for 10 years; non-smokers in CT group would receive 3 times of lung cancer screening by thoracic CT and 7 times of chest x-ray during 10 years. A pilot study was performed to evaluate the feasibility of the trial. A letter for recruitment to participate in the above trial was mailed to the citizens in Hakui City, who were 50-64 years old and underwent regular lung cancer screening using chest x-ray this year. In the letter we explained that the efficacy of lung cancer screening by thoracic CT had not been proved yet; only half of the participants could undergo thoracic CT screening; thoracic CT screening might cause unfavorable consequences like radiation exposure, false positives or overdiagnosis. Of 329 persons who received the letter of recruitment, 117 replied. After meeting with us for detailed explanation, 111 persons participated in the above randomized trial. The compliance of recruitment is high (approximately one third) and the above trial may be feasible. (author)

    Fifty patients with peritonitis carcinomatosa were evaluated with computed tomography (CT). CT findings included evidence of mesenteric thickening (60 %), solid mass (20 %), loculated ascites (16 %), ascites (14 %), partly dilated intestine (10 %). Mesenteric thickening showed both intraperitoneal and subperitoneal metastasis. Arrested flow of ascitic fluid (loculated ascites) was one of the most predicting findings of peritonitis carcinomatosa. The seven false negative cases related to small metastatic foci, long distance between autopsy and the last CT examination, or paucity of intraabdominal fat. (author)

    CT is a valuable tool in assessing thoracic gunshot wounds. CT is also the method of choice in emergency, because it permits rapid depiction of bullet damage to the chest and to other body districts. This in turn permits correct assessment of the main thoracic injuries, plus adequate and prompt planning of surgical treatment or support intensive care. It is reported on the role of CT in diagnosing the complex pleuropulmonary, cardiovascular and thoracic wall injuries caused by gunshot wounds, with their specific and acute signs which differ greatly fro those of other types of chest trauma. In the last 4 years, it was observed an amount of 76 cases of gunshot injury, twenty-six of them involved the chest. The patients, 25 men and 1 woman (mean age: 32 years, range: 17-48), were all submitted to emergency CT with iv contrast agent injection and the CT-angiography technique. The reanimator was always presented to monitor the patients' vital functions and shock state. CT of the chest was integrated with CT of the abdomen and pelvis in 4 cases and with CT of the skull in 3 cases, to detect associated bullet wounds if any. Chest radiography shows major gunshot wound damage to the chest and lungs, except for heart injuries and minimal pneumothorax. When abdominal and skull injuries are associated, CT should be the method of choice because it permits prompt and panoramic assessment of the severity of pulmonary and extra thoracic damage. This results in prompt and targeted treatment, avoiding unnecessary delays which may damage the patient further.

    We performed dynamic CT in 30 cases of hepatocellular carcinoma, and concluded as below. 1 Decting the stain in the early phase of the dynamic series, it is possible to make a diagnosis of hepatocellular carcinoma. 2 The dinamic CT is effective in a case of small hepatocellular carcinoma in which it is difficult to gain an accurate diagnosis in the routine CT study. 3 The dynamic CT is also effective in the differential diagnosis of hepatic lesions, as other hepatic lesions such as hemangioma and metastatic liver cancer show different patterns compared with hepatocellular carcinoma.

    In this paper we present an overview of CT-Urography. With the advent of multislice CT scanners and the evolution of image processing methods this technique now affords optimal urographic images comparable to those obtained with conventional techniques. We describe the acquisition techniques and protocols used by the various authors. Effective radiation dose has conditioned the use of CT-Urography so that the tendency today is to reduce the number of scans by performing, after the non enhanced scan, a single contrast-enhanced scan comprising both the nephrographic and urographic phase. With the use of multislice CT the quality of the urogram improves with the number of slices. We illustrate a variety of processing techniques, multiplanar reconstruction (MPR), maximum (MIP) and average intensity projection (AIP) and volume rendering (VR) and present a series of upper urinary tract tumours testifying to the superiority of the AIP technique over MIP. We then review the results of comparative studies of CT-Urography with conventional urography in upper urinary tract diagnostics. Finally, we describe the advantages and limitations of CT-Urography [it

    Computor tomographic images of 11 patients who had had thymectomy for myasthenia gravis or thymoma were studied retrospectively. Of those 11 patients, malignant thymoma and benign condition including normal thymus were 6 and 5 respectively. On CT, calcification and lobulation with irregular margin seem to be reliable findings of malignancy. Defect or abscence of fatty plane and non-homogenous density are ancillary. (author)

    The purpose of this study is to assess the utility of CT paging arteriography with a multidetector-row CT as a replacement for conventional angiography in the evaluation of splanchnic arterial anomalies. Sixty-three patients underwent CT paging arteriography with a multidetector-row CT. In the 56 patients with conventional angiographic correlation, there was only one minor disagreement with CT paging arteriography. In the 7 patients who underwent IVDSA (intra venous digital subtraction angiography), CT paging arteriography defined four hepatic arterial anomalies which could not be depicted by IVDSA. In conclusion, CT paging arteriography provides noninvasive means to identify splanchnic arterial anomalies. (author)

    Pelvimetry aims at providing the obstetrician with information on the size and morphology of the female pelvis, thus enabling him to assess the obstetrical prognosis as accurately as possible. Computed tomography (CT) has several advantages, in particular the lower mother and fetus radiation dose. After a brief description of obstetrical anatomy, the usual CT exploration method is presented and its results are considered in terms of measurements, indices and morphological findings. If performed with a very strict exploration procedure, CT pelvimetry is a very reliable, fact and comfortable method of examination. All these advantages, combined with the minimized patient dose, should lead to an increasingly widespread use of this technique [fr

    Normal renal dynamic CT findings of 57 cases were analysed in termes of sequential change of renal parenchymal CT image. Cortex, outer medulla and inner medulla were delineated and their sequential CT image was well correlated with the anatomicophysiological character of the kidney. Dynamic CT of 32 abnormal cases showed abnormal sequential CT findings explaining the mechanism of the abnormalities. Especially, delayed enhancement of renal cortex was noted in 17 of 19 kidneys with arterial obstruction and delayed enhancement of renal medulla in 22 of 25 cases with renal dysfunction. Compaired with excretory urography in 11 cases with renal dysfunction, advantage of dynamic CT were noted. (author)

    Computed Tomography (CT) scanner is a high radiation imaging modality compared to radiography. The dose from a CT examination can vary greatly depending on the particular CT scanner used, the area of the body examined, and the operating parameters of the scan. CT is a major contributor to collective effective dose in diagnostic radiology. Apart from the clinical benefits, the widespread use of multislice scanner is increasing radiation level to patient in comparison with conventional CT scanner. So, it becomes necessary to increase awareness about the CT scanner. (author)

    CT is useful in the evaluation of patients with newly diagnosed or highly suspected lung cancer. The principal role of CT is to screen those patients with metastatic disease beyond the hili from an attempt at curative thoracotomy. While CT is regarded as very sensitive, it is not considered highly specific, and thus a surgical procedure is usually recommended for definitive diagnosis of most ''positive'' CT findings. However, the authors demonstrate a few characteristic CT findings that are highly predictive of unresectable metastatic disease. These CT findings include massive mediastinal lymphadenopathy, diffuse mediastinal infiltration, pericardial involvement, vascular encasement, and advanced chest wall invasion

    Computed tomography (CT) of ten patients with medulloblastomas was evaluated. Six of them showed solid, nearly homogeneous lesions and a definite enhancement after the infusion of the contrast medium. However, 4 cases showed heterogenous mass lesions composed of areas of a low density and an iso- or slightly high density which was attenuated by contrast enhancement. Histological examinations revealed differentiated medulloblastomas in two of them, but the other two cases were typical medulloblastomas. It should be remembered that medulloblastomas can reveal heterogenous cerebellar midline mass lesions in CT scans. (author)

    CT pictures from 59 lesions of advanced colon cancer including rectal cancer were reviewed to evaluate a role of CT in preoperative staging diagnosis. CT findings were recorded following general rules for clinical and pathological studies on cancer of colon rectum and anus, proposed by Japanese society for cancer of colon and rectum. Tumors were detected in 90% of advanced colon cancers. Sensitivity in local extension (S factor) was 58.0%. Sensitivity in lymphonode involvement (N factor) was 50.0%. Sensitivity in final staging diagnosis, dividing colon cancer into two groups below st II and above st III, was 63.3%. Further study should be necessitated to provide useful information for preoperative staging diagnosis of colon cancer. (author)

    Surgical sponges retained after laparotomy can cause serious problem if they were not be identified in early state. In these circumstances abdominal CT yields the accurate diagnostic images. The purpose of this report is to present highly indicative findings permitting correct preoperative diagnosis of the gossypiboma. We experienced three cases in which CT showed the images sufficiently characteristic to suggest the correct preoperative diagnosis. We evaluated retrospectively the radiological images of gossypiboma confirmed by operation. Three patients were admitted due to palpable masses. Two female patients had medical histories of cesarean sections and a male patient had been operated due to malignant fibrous histiocytoma, previously. Abdominal CT scan of one case revealed huge ovoid hypodense mass with enhanced peripheral rim. Calcific spots and whirl-like stripes were noted within the lesion. Towel was found in pathologic specimen. CT images of two patients showed well-encapsulated, mixed fluid and soft tissue density mass with several gas bubbles. Surgical sponges were found within abscesses. The authors conclude that these characteristic CT findings and careful histories of surgery are very useful for correct pre-operative diagnosis and permit the guideline for the optimal plan of the surgical treatment

    Based on 17 patients with thymoma (8 with myasthenia gravis and 9 free from it); 1. The effectiveness of CT, conventional radiography and pneumomediastinography in the detection of thymomas was determined and the results compared. 2. The CT findings of thymomas were discussed and the CT features which seemed to suggest malignant thymomas were evaluated. The results were as follows: 1. Of the 17 cases with thymomas, 13 were diagnosed from p-a films, 13 from lateral films, and 16 from CT. Of the 16 thymomas, 14 were diagnosed from lateral tomography. Mass densities were shown in all 15 cases in which pneumomediastinography were performed. 2. Benign thymomas showed round or oval smoothly marginated mass. The fatty plane between the mass and the mediastinal structures was nicely preserved. 3. Malignant thymoma frequently showed a plaque-like mass with more or less irregular or lobulated contoures with obliteration of the fatty planes of the cardiovascular structures. Tumor calcification was shown in 4 of 10 malignant thymomas. 4. Slight tumor invasion to the mediastinal pleura and lung was difficult to predict from the CT images. (author)

  6. Personal attributes of authors and reviewers, social bias and the outcomes of peer review: a case study [v2; ref status: indexed, http://f1000r.es/5gj

    Full Text Available Peer review is the "gold standard" for evaluating journal and conference papers, research proposals, on-going projects and university departments. However, it is widely believed that current systems are expensive, conservative and prone to various forms of bias. One form of bias identified in the literature is “social bias” linked to the personal attributes of authors and reviewers. To quantify the importance of this form of bias in modern peer review, we analyze three datasets providing information on the attributes of authors and reviewers and review outcomes: one from Frontiers - an open access publishing house with a novel interactive review process, and two from Spanish and international computer science conferences, which use traditional peer review. We use a random intercept model in which review outcome is the dependent variable, author and reviewer attributes are the independent variables and bias is defined by the interaction between author and reviewer attributes. We find no evidence of bias in terms of gender, or the language or prestige of author and reviewer institutions in any of the three datasets, but some weak evidence of regional bias in all three. Reviewer gender and the language and prestige of reviewer institutions appear to have little effect on review outcomes, but author gender, and the characteristics of author institutions have moderate to large effects. The methodology used cannot determine whether these are due to objective differences in scientific merit or entrenched biases shared by all reviewers.

State new hypotheses when war¬ranted, but label them clearly.g. Referencesi. General Considerations Related to References Authors should provide direct references to original research sources whenever possible. References should not be used by authors, editors, or peer reviewers to promote self-interests. Although references to review articles can be an efficient way to guide readers to a body of literature, review articles do not always reflect original work accurately. On the other hand, extensive lists of references to original work on a topic can use excessive space. Fewer references to key original papers often serve as well as more exhaustive lists, particularly since references can now be added to the electronic version of published papers, and since electronic literature searching allows readers to retrieve published literature efficiently.Do not use conference abstracts as references: they can be cited in the text, in parentheses, but not as page footnotes. References to papers accepted but not yet published should be designated as “in press” or “forthcoming.” Information from manuscripts submitted but not accepted should be cited in the text as “unpublished observations” with written permission from the source.Avoid citing a “personal communication” unless it provides essential information not available from a public source, in which case the name of the person and date of communication should be cited in parentheses in the text. For scientific articles, obtain written permission and confirmation of accuracy from the source of a personal communication.Some but not all journals check the accuracy of all reference citations; thus, citation errors sometimes appear in the published version of articles. To minimize such errors, references should be verified using

    Twenty-seven cases of small hepatic tumors were examined by MRI and CT (ICT). MRI was more sensitive than plain and contrast CT. But ICT could detect more small lesions than MRI. CT is not more superior modality than MRI untill ICT is performed. It is concluded ICT should be done when diagnosing small hepatic tumors by CT. (author)

    Plain CT scanning of the kidney was performed in 16 patients with renal failure whose basic renal disorder had been not necessarily known beforehand. The findings of the CT examination were composed of renal atrophy of various degree (12 cases), cystic lesions (8 cases), polycystic renal disease (one case), nephrosclerosis (2 cases), hydronephrosis (2 cases), ureter and renal stones (one case), and normal CT profile (2 cases). Being based on these CT findings and other clinical informations, basic renal disorders could be either presumed or confirmed. It was concluded that plain CT scanning of the kidney was useful to decide a method of treatment and to estimate prognosis in patients with renal failure. (author)

    Brown-Roberts-Wells stereotactic instruments were used for CT guided stereotactic surgery in 54 cases (65 operations). Stereotactic biopsy was done in 9 cases and successive regional chemotherapy was done in 3 cases. Stereotactic drainage was done in 2 cases of bacterial abcess, 3 cases of cystic neoplasm and 33 cases (43 operations) of intracerebral hematoma. CT guided stereotactic procedure was valuable for the correct cannulation to the center of the cavity. We tried to utilize CT image for the selection of targets for stereotactic functional neurosurgical procedures in 6 cases. In the cases of thalamotomy, the information derived from CT made the operation safer than that by contrast ventriculography alone. In all cases of electrode implantation for deep brain stimulation, accurate and precise electrode placement was achieved from CT images alone. This rapid and easy surgical technique was useful also for poor risk patients. (author)

    The assessment of functional status is a critical component of clinical neuropsychological evaluations used for both diagnostic and therapeutic purposes in patients with cognitive brain disorders. There are, however, no widely adopted neuropsychological tests that are both ecologically valid and easily administered in daily clinical practice. This discrepancy is a roadblock to the widespread adoption of functional assessments. In this paper, we propose a novel approach using a serious game authoring platform (eAdventure) for creating screen-based simulated functional assessments. We created a naturalistic functional task that consisted of preparing a cup of tea (SBS-COT) and applied the assessment in a convenience sample of eight dyads of therapists/patients with mild executive dysfunction after traumatic brain injury. We had three main aims. First, we performed a comprehensive review of executive function assessment in activities of daily living. Second, we were interested in measuring the feasibility of this technology with respect to staffing, economic and technical requirements. Third, a serious game was administered to patients to study the feasibility of this technology in the clinical context (pre-screening test). In addition, quantitative (Technology Acceptance Model (TAM) questionnaires) and qualitative (semistructured interviews) evaluations were applied to obtain user input. Our results suggest that the staffing, economic and technical requirements of the SBS-COT are feasible. The outcomes of the pre-screening test provide evidence that this technology is useful in the functional assessment of patients with executive dysfunction. In relation to subjective data, the TAM questionnaire showed good user acceptability from a professional perspective. Interview analyses with professionals and patients showed positive experiences related to the use of the SBS-COT. Our work indicates that the use of these types of authoring platforms could have positive long

    On the basis of brain CT studies of 150 patients of the clinic for persons with Alzheimer's disease the diagnostic utility of measurement of hippocampal fissure and craniocerebral ratios was assessed. In analyzed group hippocampal fissure measurements greater than 4 mm occurred only in patients with symptoms of Alzheimer's type dementia. The measurement showed 90% sensitivity and 70% specificity as the prognostic factor of clinical course, especially at the first part of the disease. The evaluation of the hippocampal fissure in conjunction with detailed analysis of CT picture of the atrophic brain allowed for precise final diagnosis. (author)

    Fifteen CT pictures from 10 cases of hepatic abscess were reviewed. Rim enhancement was noted only in 2. On the other hand, ill defined low density surrounding central cystic structure was demonstrated in 11. Following contrast injection, this ill defined low density becomes isodense to the normal liver. Histologically, the ill defined low density was granulation tissue composed of neutrophils, lymphocytes and Macrophages. We emphasized the importance of the recognition of the granulation tissue surraounding a cyst of hepatic abscess. (author)

    The clinical and CT findings in 10 patients with primary pontine hemorrhage were reviewed. All patients were hypertensive. Pontine hemorrhage can be divided into 3 groups from the viewpoint of location of hematomas. These are the tegmentobasilar type, tegmental type and basilar type. The tegmentobasilar type produces characteristic clinical features for pontine hemorrhage and poor prognosis, otherwise, another two types produce atypical clinical features for pontine hemorrhage and good prognosis.

    1998-01-01

    Although colonic diverticulitis has no indication for operation, but in some mistaken cases were operated with a diagnosis of acute appendicitis. We evaluated the CT findings of colonic diverticulitis about 19 cases and of asymptomatic colonic diverticula about 15 cases retrospectively. Diagnosis was confirmed of barium enema and operation. CT are complementary methods of examination that can delineated the range of thickening of the colon and the extension of inflammatory changes around the colon. We also believe that CT findings of colonic diverticulitis are useful for differentiating from a diagnosis of appendicitis. (author)

    CT scan was performed in two cases of annular pancreas which could be found in one case preoperatively and in the other case retrospectively. CT scan demonstrated secondary changes of annular pancreas such as medial displacement and dilatation of the duodenal bulb in the former case and stenosis of the duodenal loop and thickened soft tissue density around the narrow segment of the duodenal loop in the latter case, although it failed to demonstrate the peninsular protrusion of the parenchyma of the pancreas head. These findings suggest high possibility of diagnosing annular pancreas by CT scan. (author)

Author analyse and present CT appearance of pulmonary ligament of the 40 normal and abnormal patients on the basis of anatomic knowledge from the cross section of cadaver. Left pulmonary ligament is more frequency visualized than the right. The most important CT landmark in localizing pulmonary ligament is the esophagus where the ligament attaches on its lateral wall. Pitfalls in CT identification of pulmonary ligament are right phrenic nerve and right pericardiacophrenic vessels which emerge from lateral wall of the IVC and wall of the emphysematous bulla in the region of the pulmonary ligament.

    Full text: Cancer of the urinary bladder is one of the commonest urothelial neoplasms. Conventional cystoscopy remains the mainstay in the diagnosis of urinary bladder carcinomas. But it is an invasive and uncomfortable procedure, associated with complications. Computed tomographic (CT) virtual cystoscopy has been proposed as an alternative imaging modality with potential advantages in the detection of urinary bladder neoplasms and good patient acceptance. It is a minimally invasive technique, allowing imaging of the urinary bladder in multiple planes and a 360 0 view. CT cystoscopy provides information about the location, size and morphologic features of urinary bladder lesions, indicating appropriate areas for biopsy. It can be performed in cases in which conventional cystoscopy is not feasible, such as in the presence of urethral strictures, marked prostatic hypertrophy or active bleeding, and in cases in which cystoscopic findings are inconclusive. The technique can be used to evaluate areas of the urinary bladder difficult to evaluate with cystoscopy, such as the anterior bladder neck and narrowmouthed diverticula. Finally, virtual cystoscopy provides both intraluminal and extraluminal pathologic changes, so intravesical disease and exrtavesical extension can be evaluated in the same study. One of the limitations of this technique is the difficulty to demonstrate small-sized lesions. The introduction of multi-detector row CT (MDCT) scanners was a major technological advancement because among other things it substantially improves z-axis resolution by reducing section collimation and allowing the detection of very small lesions. The near isotropic or isotropic pixels achieved with a multidetector CT scanner, enable the creation of multiplanar reformatted images with a resolution very close to that of the axial images and three-dimensional (3D) renderings of outstanding quality. Transverse, multiplanar reformations and virtual endoscopic images are complementary

    Computed tomographic (CT) findings of pancreatic ductal adenocarcinoma were studied with the combined method of early enhancement CT and high dose enhancement CT in 72 carcinomas. Common Findings were change in pancreatic contour, abnormal attenuation in a tumor and dilatation of the main pancreatic duct. The incidence of abnormal attenuation and dilatation of the main pancreatic duct and bile duct was constant regardless of tumor size. The finding of hypoattenuation at early enhancement CT was most useful for demonstrating a carcinoma. However, this finding was negative in ten cases, five of which showed inhomogenous hyperattenuation at high dose enhancement CT. The detection of change in pancreatic contour and dilatation of the main pancreatic duct was most frequent at high dose enhancement CT. The finding of change in pancreatic contour and/or abnormal attenuation in a tumor could be detected in 47 cases at plain CT, 66 at early enhancement CT and 65 at high dose enhancement CT. Since the four cases in which neither finding was detected by any CT method showed dilatated main pancreatic duct, there was no case without abnormal CT findings. This combined CT method will be a reliable diagnostic technique in the imaging of pancreatic carcinoma. (author)

    The purpose of this paper is to provide a author capability of current author indexing practices in journal literature indexing practices in 'Journal of Nuclear Science and Technology of Japan'. This Journal employed keywords freely assigned by author and not taken from INIS Thesaurus or other vocabulary list. Author examined 413 literatures, comparing keywords assigned by the literatures' authors with descriptor's (ATOMINDEX) assigned by an experienced professional indexer. The results of the comparisons showed that the average set of terms assigned by author included about 70% of all the terms assigned to the same literature by the professional indexer. Authors eventually would contribute, for the most effective point to create reference to information is at the time of its generation. Consequently, it may be possible to transfer them easily to descriptors in every secondary information system. (author)

    CT was performed in 104 patients with abdominal pain suspected appendicitis. CT showed positive finding (abnormal appendix, appendicolith, pericecal inflammatory change, fluid collection, LN swelling, abscess) and complication of appendicitis clearly. CT diagnosis showed high accuracy than clinical diagnosis. CT proved its usefulness especially only CT imaging showed the correct diagnosis. On the other hand, diverticulitis and terminal ileitis common diagnostic disease of appendicitis showed similar clinical appearance and CT image, caused to be difficult to diagnose correctly. In the cases showing similar image to appendicitis or atypical image, CT also proved its limit of the diagnosis on appendicitis. (author)

  20. CT number of the fatty liver

    International Nuclear Information System (INIS)

    Maeda, Hiroko; Kawai, Takeshi; Kanasaki, Yoshiki; Akagi, Hiroaki

    1981-01-01

    This report is studied on CT number and CT images of the eight cases with fatty liver. Five of these cases showed the reversal of densities of the liver and vessels. In these cases, the diagnoses of the fatty liver were easible. In other cases, the diagnoses were possible only by comparison of the CT number of the liver and spleen because the CT number of normal liver were higher than those of the spleen. In the results which we examined the correlation of the CT number and specific gravities of the blood, normal saline, distilled water, mayonnaise, eatable iol, ethyl alcohol and lard, we observed the linear relationship between CT number and specific gravities. And so, we think that the diagnosis of the fatty liver and the degree of fatty infiltration can be guessed by the CT number of the liver and spleen. (author)

    2012-09-01

    Computerized Tomography (CT) is now one of the most important radiological examinations world wide.The frequency of CT examinations is increasing rapidly from 2% of all radiological examinations in some countries a decade age to 10-15% now. During the imaging procedure, staff may expose to a significant dose. Therefore, ambient dose measurement is important in the shortage of regular personal monitoring in sudan. This study intended to evaluate the ambient dose at some CT departments (Medical Military hospital, Alamal National Hospital, Elnelin Diagnostic Center and Modern Medical Centre). These departments were equipped with daul, 16 and 64 multi detector CT machines. A survey meter (Radios) was used to measure ambient doses in three locations: Doors, Control Rooms and Adjacent Rooms. The ambient dose equivalent (scatter dose) was measured at various distances from the isocenter of the CT unit at various angles to establish isodose cartography. The mean and range of radiation at control room is 10.00-0.20 and mean (7.05μSv/hr,) reception 1.0-0 (0.40) and doors 4.00-100.00 (73.5) for height 1 meter above the ground. For height 2 meters at control room 0-10.00 (6,75), reception 0-90.00 (30) at door 9.00-90.00 (49.50). This study confirms that low levels of radiation dose are received by staff during CT imaging and these levels are within safe limits as prescribed by the national and international regulations.

    1986-01-01

    Computed tomography has the ability to evaluate maxillofacial trauma quickly. The well-known contrast resolution capabilities of CT play a role in the usefulness of this modality. However, it is the image manipulation capability which is of singular advantage in these cases. The spatial resolution of computed tomography has matched that of conventional pluridirectional tomography in current generation equipment. Since a set of axial CT sections can be obtained with automatic table incrementation within 12 minutes, the information content per time of study ratio is improved over that of conventional tomography, despite the fact that image reformation requires extra time on the part of the radiologist. Radiation savings are significantly in favor of computed tomography as well. In the authors' experience, computed tomography is the primary diagnostic imaging modality used in the evaluation of complex facial trauma, after routine screening films are obtained

    Generally, CT scans reveal a decrease in the volume of the ventricular system, sylvian fissures and cortical sulci in the acute stage of encephalitis, and softening of the cerebral lobes with dilatation of the lateral ventricles and subarachnoidian dilated spaces in the chronic stage. We encountered three cases of encephalitis: mumps (case 1), herpes simplex (case 2), and syphilis (case 3). In case 1, brain edema was seen in the acute stage and brain atrophy in the chronic stage. In case 2, necrosis of the temporal pole, which is pathognomonic in herpes simplex encephalitis, was recognized. And in case 3, multiple lesions whose CT appearance was enhanced by contrast materials were found scattered over the whole brain. These lesions were diagnosed as inflammatory granuloma by histological examination. (author)

    The CT findings for four patients with mucopolysaccharidosis were analyzed using a Delta scan-25 (Ohio Nuclear). In three cases of Hunter's syndrome (MPS IIA 13-year-old male, MPS IIB 12-year-old male, and 25-year-old male), a dilatation of the cortical sulci was observed. Moderate dilatations were also seen in the basal cistern, the quadrigeminal cistern, and the ambient cistern. In one case of Hunter's syndrome, a low-density area was observed in the bilateral tharamic regions. An irregular low-density area was also seen in the white matter in some cases. PVL was not apparent in any case. Marked ventricular dilations were observed in cases with mental retardation, for example, in one case of Hurler's syndrome (8-year-old male) and one case of MPS IIA. The circulation and absorbtion of CSF in cortical snbarachnoid spaces were supposed to be moderately retarded by metrizamide CT cisternography. (author)

    We assessed the prevalence of emphysematous changes among healthy workers and retired persons, using subjective evaluations of low-dose spiral CT images obtained during thoracic CT screenings for lung cancer. Among 6144 male participants (50-69 years old; mean age, 57), we detected 686 cases (11.2%) with emphysematous changes. The majority (95.3%) of CT-detected emphysema cases were in current or former smokers, and 169 cases (24.6%) showed significant obstructive impairment. Of 236 cases with emphysematous changes in the internal region (more than 20 mm from the costal margin), 98 (41.5%) had significant obstructive impairment. Smoking was found to be the major risk factor for CT-detected emphysema. Longitudinal observation of the emphysema cases, as well as health care support for cessation of smoking, is very important.

    Postmortem radiology is a rapidly developing specialty that is increasingly used as an adjunct to or substitute for conventional autopsy. The goal is to find patterns of disease and possibly the cause of death. Postmortem CT images bring to light processes of decomposition most radiologists are unfamiliar with. These postmortem changes, such as the formation of gas and edema, should not be mistaken for pathological processes that occur in living persons. In this review we discuss the normal postmortem thoraco-abdominal changes and how these appear on CT images, as well as how to differentiate these findings from those of pathological processes.

  8. CT of pancreatitis

    International Nuclear Information System (INIS)

    Fukuda, Toshio

    1990-01-01

    One hundred and two cases of acute and chronic pancreatitis were studied by computed tomography. Fluid collection was detected by CT in 45 cases, and the common extrapancreatic sites of involvement included the lesser sac (13 cases), anterior pararenal space (9 cases), transverse mesocolon (7 cases) and posterior pararenal space (5 cases). Ten cases of spontaneous resolution of pancreatic pseudocysts were encountered. Cystojejunostomy was done on 6 patients. A 4-to-6-weeks time interval has been currently accepted as necessary for pseudocyst wall maturation. However, the surgery was not possible in two patients in this series since the cyst wall was too thin. It is considered that the time over 3 months is required for surgical anastomosis of the cyst to the gastrointestinal tract. Pancreatic abscess has become the most common cause of death from pancreatitis. In this series pancreatic abscess occurred in 8 patients. Gas collection in the pancreas was observed in only one patient. In the other patients, pseudocysts had become infected and converted to abscesses. The CT number of 4 infected pseudocysts was less than 15 HU. Thus, it was not possible to distinguish infected from noninfected pseudocysts by CT. The author studied 9 patients with focal inflammatory mass of the pancreas with histologically proved severe fibrosis. All masses were small. Angiography showed occlusion or marked stenosis of the splenic vein in 3 cases. The postcontract CT (after intravenous bolus injection) in 7 cases of focal inflammatory mass demonstrated almost equal enhanced effect of the mass as compared with the adjacent normal pancreatic parenchyma. This finding is considered to be useful in distinguishing inflammatory mass from pancreatic carcinoma. (author)

    Objective: An evaluation of CT diagnosis of abdominal trauma. Methods: CT appearance of abdominal trauma was analyzed retrospectively in 95 cases. thirty-three patients were cured by operation, and the other 59 patients received conservative treatment. Fifty-one patients out of 59 were seen healed or improved by a follow up CT scan after the conservative treatment. Results: The study included: 31 cases of splenic contusion, accompanying with hemoperitoneum in 25 cases; 3 cases of hepatic laceration; 33 cases of liver and spleen compound trauma accompanying with hemoperitoneum; 18 cases of renal contusion, with subcapsular hemorrhage in 12 cases; 4 cases of midriff colic; 3 cases of mesentery breach; 3 cases of digestive tract perforation. Conclusion: CT is sensitive and precise in evaluating abdominal trauma, providing important information for treatment. (author)

  10. CT findings of muscular dystrophy

    International Nuclear Information System (INIS)

    Saitoh, Hiroshi

    1991-01-01

    CT scans of muscles in patients with limb girdle type (LG), myotonic type (MYD) and Duchenne type (DMD) dystrophies were obtained at five different body levels: the neck, L3 vertebral body, pelvic girdle, thigh and lower leg. CT numbers, cross sectional areas (CSA) and %CSA of muscle or fat were evaluated in each muscle. The characteristic CT patterns for each type of muscular dystrophy were obtained. Compared with DMD, the gracilis and soleus were more severely damaged in LG and the biceps femoris remained relatively preserved among the hamstrings. In addition, the multifidus of the neck and sternocleidomastoid also were more severely damaged in MYD. This study suggests that CT scan will be useful in the differential diagnosis of these types of muscular dystrophy as well as in planning appropriate rehabilitation and detecting damaged muscles.

    2000-01-01

    Among the new applications of helical CT is the study of the ureteral pathology. The objective of this paper was to evaluate patients with suspected pathology of this organ and the repercussion in the therapeutic plans. We studied 23 patients with a helical CT protocol, without IV contrast injection and performed multiplanar reconstruction (MPR). We called this procedure Pielo CT. Thirteen ureteral stones were detected, 6 calculi, 2 urinary tract tumors, dilatation of the system in a patient with neo-bladder. In 2 patients, in whom ureteral pathology was ruled out, we found other alterations that explained the symptoms, (gallbladder stones, disk protrusion). The Pielo CT let decide a therapeutical approach in 20 or 21 patients with ureteral pathology. (author)

    CT scan is widely used in orthopedic examinations. By three-dimentional display of the form of bone and joint, the change of form can be identified and the lesion can be located. CT figures were stereographically processed using a personal computer to display the images of the hip joints. The outlines of the bone seen on the CT film were directly traced with a digitizer, then the A/D converted coordinate data were obtained. The data for each slice were input to the personal computer. After conversion to normal coordinate and magnification, the data were filed on the floppy disc. These data were regained from the disk and made affin transformation to display the stereographic images of the hip joints. In a case of solitary bone cyst of the coxal bone, this method helped us to decide the appropriated surgical approach. For the congenital dysplasia of the hip, acetabular coverage was examined three-dimensionally and postoperative changes were assessed in the cases of shelf operation and intertrochanteric extension osteotomy. In the cases of aseptic necrosis of the femoral head, location and size of the necrotic area were clearly visualized and the appropriate surgical procedure could be decided. Moreover, it was useful to decide the degree of rotation of the femoral head in rotational osteotomy. (author) 61 refs.

  8. Usefulness of multi-plane dynamic subtraction CT (MPDS-CT) for intracranial high density lesions

    Energy Technology Data Exchange (ETDEWEB)

    Takagi, Ryo; Kumazaki, Tatsuo [Nippon Medical School, Tokyo (Japan)

    1996-02-01

    We present a new CT technique using the high speed CT scanner in detection and evaluation of temporal and spatial contrast enhancement of intracranial high density lesions. A multi-plane dynamic subtraction CT (MPDS-CT) was performed in 21 patients with intracranial high density lesions. These lesions consisted of 10 brain tumors, 7 intracerebral hemorrhages and 4 vascular malformations (2 untreated, 2 post-embolization). Baseline study was first performed, and 5 sequential planes of covering total high density lesions were selected. After obtaining the 5 sequential CT images as mask images, three series of multi-plane dynamic CT were performed for the same 5 planes with an intravenous bolus injection of contrast medium. MPDS-CT images were reconstructed by subtracting dynamic CT images from the mask ones. MPDS-CT were compared with conventional contrast-enhanced CT. MPDS-CT images showed the definite contrast enhancement of high density brain tumors and vascular malformations which were not clearly identified on conventional contrast-enhanced CT images because of calcified or hemorrhagic lesions and embolic materials, enabling us to eliminate enhanced abnormalities with non-enhanced areas such as unusual intracerebral hemorrhages. MPDS-CT will provide us further accurate and objective information and will be greatly helpful for interpreting pathophysiologic condition. (author).

    1981-01-01

    CT scans were obtained on 33 patients (age 73y. to 31y.) with the diagnosis of normal pressure hydrocephalus. In each case, the diagnosis was made on the basis of the symptoms, CT and cisternographic findings. Underlying diseases of normal pressure hydrocephalus are ruptured aneurysms (21 cases), arteriovenous malformations (2 cases), head trauma (1 case), cerebrovascular accidents (1 case) and idiopathie (8 cases). Sixteen of 33 patients showed marked improvement, five, moderate or minimal improvement, and twelve, no change. The results were compared with CT findings and clinical response to shunting. CT findings were classified into five types, bases on the degree of periventricular hypodensity (P.V.H.), the extent of brain damage by underlying diseases, and the degree of cortical atrophy. In 17 cases of type (I), CT shows the presence of P.V.H. with or without minimal frontal lobe damage and no cortical atrophy. The good surgical improvements were achieved in all cases of type (I) by shunting. In 4 cases of type (II), CT shows the presence of P.V.H. and severe brain damage without cortical atrophy. The fair clinical improvements were achieved in 2 cases (50%) by shunting. In one case of type (III), CT shows the absence of P.V.H. without brain damage nor cortical atrophy. No clinical improvement was obtained by shunting in this type. In 9 cases of type (IV) with mild cortical atrophy, the fair clinical improvement was achieved in two cases (22%) and no improvement in 7 cases. In 2 cases of type (V) with moderate or marked cortical atrophy, no clinical improvement was obtained by shunting. In conclusion, it appeared from the present study that there was a good correlation between the result of shunting and the type of CT, and clinical response to shunting operation might be predicted by classification of CT findings.

    1989-01-01

    Peritoneal metastasis is frequent mode of dissemination of intraabdominal malignancies. Radiologic diagnosis of peritoneal metastasis has relied on indirect evidence on a barium UGI series and small bowel examination. With the advent of CT scanning, CT is capable of direct imaging of peritoneum. The sensitivity of CT in detecting peritoneal metastasis and CT manifestation of peritoneal metastatic lesions had reported occasionally, but rarely in Korea. So, authors illustrated the CT manifestation of peritoneal metastatic lesions in 32 cases of macroscopically proven cases in laparoscopy or laparotomy in Korea University Hae Wha Hospital during recent 4 years. The results are as follows. 1. Of total 32 cases, 18 cases were male and 14 cases were female. Age incidence was the most common in 6th decade. 2. The most common type of malignancy that cause peritoneal metastasis was the stomach cancer and next common type of malignancies were pancreas cancer in men and ovarian cancer in women. 3. Of total 32 cases of peritoneal metastasis which was confirmed by laparoscopy or laparotomy macroscopically, 23 cases (72%) were detected peritoneal thickening and/or omental pathology by CT, and the remaining 9 cases (28%) were not detected by CT. 4. Ascites was present in 19 cases (59%). 5. Parietal peritoneal thickening was present in 16 cases (50%) by CT and sheetlike pattern was the most common findings. The patterns of peritoneal thickening was relatively nonspecific and was not correlated with primary tumor type. 6. Tumor involvement of greater omentum by CT was present in 19 cases (59%). There were 7 cases of smudged appearance pattern, 6 cases of nodular pattern, 6 cases of omental cake pattern and no cystic mass pattern. The patterns of omental pathology was relatively nonspecific and was nor correlated with primary tumor type

    2005-11-15

    With the advent of multidetector row CT scanners, evaluation of the urothelium of the entire urinary tract with high-resolution thin sections during a single breath-hold has become a reality. Multidetector CT urography (MDCTU) is a single examination that allows evaluation of potential urinary tract calculi, renal parenchymal masses, and both benign and malignant urothelial lesions. Initial results with this new technique are encouraging. Current investigations of MDCTU focus on methods to improve opacification and distension of the upper urinary tract - the collecting systems, pelvis, and ureters. The role of abdominal compression, infusion of saline and/or furosemide, and optimal time delay of excretory phase imaging is being explored. Upper tract urothelial malignancies, including small lesions less the 5 mmin diameter, can be detected with high sensitivity. Methods to reduce radiation exposure are being explored, including split-bolus contrast injection techniques that combine nephrographic and excretory phases into a single phase. It is likely that in the near future, radiological evaluation of significant unexplained hematuria or of known or prior urothelial malignancy will consist of a single examination - MDCTU. (orig.)

    A new CT-stereotactic device (navigator) has been developed which translates the operating site into preoperative CT coordination. We applied this system in combination with three-dimensional CT reconstruction and with angiogram. Method: The system consists of a 6-joint robotic arm and a personal computer. It projects the location of the arm tip onto a correlating CT slice with a cursor, which guides a surgeon toward his intracranial target during open surgery. The system translates the tip location into a 3D-CT reconstructed image and an angiogram. The system worked as the core of a multimodality navigation system during surgery. The detection error was less than 5 mm, which proved sufficient for open microsurgery. The system was combined with a 3D-CT reconstruction system. It produces 3D images and cuts off the surface image at the point of the cursor, simulating surgical excision. The navigator controlled the location of the cutting cursor, thus establishing a real-time surgical simulation. When the angiogram was referred to, it became easy to identify bridging veins within a small operating field. Conclusion: The neuronavigator combines various diagnostic images into one data base and effectively guides the surgeon during surgery. (author).

    Full Text Available In this article, the authors suggest that one method for increasing awareness of the benefits of data sharing can be affected by administering a survey, hopefully encouraging either a minority or majority influence on other members of the behavioural science community. The authors describe the process for creating such a survey and provide their survey, although untested. This is a well-timed article as the existing literature on social and behavioural science data is quite thin. The majority/minority influence of norms is a nice theoretical construct to explore. This is definitely one approach to increase awareness of the benefits of data sharing.

    International Nuclear Information System (INIS)

    Nishizawa, Kanae; Maruyama, Takashi; Matsumoto, Masaki; Iwai, Kazuo

    2004-01-01

    Computed tomography (CT) has been established as an important diagnostic tool in clinical medicine and has become a major source of medical exposure. A nationwide survey regarding CT examinations was carried out in Japan in 2000. CT units per million people in Japan numbered 87.8. The annual number of examinations was 0.1 million in those 0-14 years old, 3.54 million for those 15 years old and above, and 3.65 million in total. Eighty percent of examinations for those 0-14 years old were examinations of the head, as were 40% for those 15 years old and above. The number of examinations per 1000 population was 290. The collective effective dose was 295 x 10 3 person·Sv, and the effective dose per caput was evaluated as 2.3 mSv. (author)
