    Full Text Available Esophageal atresia (EA with tracheoesophageal fistula occurs in about 1:2,500 births. We report a case of persistent bronchography in a newborn with EA and distal tracheoesophageal fistula. A large amount of barium sulfate was injected for mistake by a tube directly in the right bronchus to evaluate the patency of the esophagus. The infant showed signs of respiratory distress; he was intubated and transported at children's Hospital Santobono Pausilipon. Here, it was performed a chest X-ray that confirmed the opacification of the right bronchial tree, and it was suspected an EA type 3b. The literature recommends that: evaluation of the patency of the esophagus, with an iodinate contrast medium, should be done in a pediatric specialized center for high risk of lung aspiration.

    Bronchography has been performed on 154 patients, having the infectious-allergic form of bronchial asthma. Pathologic changes on the bronchograms have been detected in 99 (64.3 %) patients. Deforming bronchitis, characterized by the different degree of manifestness and stretch, has been more frequent (49.3%), while bronchoectases (14.3%) and cirrhosis (0.7%) have been rarer findings.

    In 76 children, 102 unilateral bronchograms were compared with the results of chest radiography and Tc-99m perfusion scintigraphy to assess the presence of bronchiectasis. Additional Kr-81m ventilation lung scintigraphy was obtained in 16 patients. For the chest radiograph the sensitivity was 73% and the specificity was 76%. For lung scintigraphy the sensitivity was 92% and the specificity 60%. When both chest radiography and lung scintigraphy were considered, sensitivity reached 96% and specificity fell to 53%. Forty per cent of the bronchograms which were performed might have been avoided on the basis of the normal chest radiograph and lung scintigraphy. The combination of lung scintigraphy and chest radiography is an excellent screening method when a decision on the advisability of bronchography is being taken in children.

    To evaluate the value of dose-reduced 16-slice multidetector-row spiral computed tomography (16-MDCT) using virtual tracheobronchoscopy (VTB) and virtual bronchography (VBG) in children with suspected tracheobronchial stenosis. 12 children (4 d to 3 years, body weight 1.2 kg to 13.5 kg) with stridor and suspected tracheobronchial stenosis were examined by contrast-enhanced low-dose 16-MDCT. Conventional axial slices, MPRs, VTB, and VBG were calculated. Image findings were correlated with the results of fiberoptic bronchoscopy (12 out of 12) as a gold standard and subsequent surgery (8 out of 12). VTB and VBG demonstrated the fiberoptic bronchoscopically suspected tracheal stenosis in 11 of 12 children due to vascular compression because of the brachiocephalic trunk (6), a double aortic arch (2), a vascular compression of the left main bronchus (2), and a right aberrant subclavian artery (1). Eleven out of 12 stenoses were correctly depicted by conventional axial slices, MPRs, VTB, and VBG. Dose reduction was 79 to 85.8% compared to a standard adult chest CT. Dose-reduced 16-MDCT with the use of VTB and VBG is effective for the evaluation of tracheobronchial stenosis in children and correlates well with fiberoptic bronchoscopy. (orig.)

    Chest radiograhs revealed evidences of dilatation of the trachea and both main bronchi, multiple air bubbles around the trachea and focal bronchopneumonia in right lower lobe. Tracheobronchomegaly is a rare condition characterized by marked dilatation of the trachea and main bronchi and frequently associated with tracheal diverticulosis, bronchiectasis, and recurrent lower respiratory tract infection. Mounier-Kuhn, in 1932, was the first to associate the presence of tracheobronchomegaly with the clinical syndrome of chronic, recurrent respiratory tract infection. Tracheobronchomegaly is believed to be extremely rare. To date, only 92 cases have been reported in the literatures. We recently encountered a case of tracheobronchomegaly associated with multiple diverticula formation. The diagnosis was made by chest radiography, computed tomography (CT), bronchography, and CT taken immediately after the bronchography.

    Bronchiectasis is characterized by irreversible dilatation of the airways. Associated with a variety of underlying disorders, the common pathway for the development of bronchiectasis is chronic or recurrent infection. Bronchiectasis can occur in the normal host after a bout of severe infection or bronchial obstruction. Currently, it is more commonly seen in patients with abnormal host defenses including impaired clearance of secretions and disorders of cellular and humoral immunity. Historically, bronchography has been the imaging tool used for the evaluation of bronchiectasis. This procedure has been replaced by high resolution computed tomography, which is currently the modality of choice for imaging patients with bronchiectasis.

    Clinical, radiologic and histologic features of obliterative bronchiolitis (OB) in children were reviewed to define features helpful in early recognition. All autopsies (n = 2,897), lung biopsies (n = 244), and medical records of children followed at St. Christopher's Hospital for Children (SCHC) between 1960 and 1985 were screened. Nineteen cases of OB were confirmed using radiologic and histologic criteria. Twelve patients were diagnosed during life, and ten survived. Seven were diagnosed post mortem. OB should be considered when persistent respiratory signs and symptoms follow acute pneumonia, aspiration is known or suspected, areas of hyperlucency are seen on chest radiograph, or respiratory failure with overaeration is unresponsive to therapy. Diagnostic studies include ventilation-perfusion scan, bronchography and lung biopsy. Sequelae include dyspnea on exertion, obstructive lung disease, bronchiectasis, persistent atelectasis, and hyperlucent lung syndrome. Recognition and supportive treatment during the acute and chronic phases may improve the functional status of these patients.

    Over the past two decades there has been a phenomenal growth in the number of dedicated synchrotron radiation facilities and a corresponding growth in the number of applications in both basic and applied sciences. The high flux and brightness, tunable beams, time structure and polarization of synchrotron radiation provide an ideal x- ray source for many applications in the medical sciences. There is a dual aspect to the field of medical applications of synchrotron radiation. First there are the important in-vitro programs such as structural biology, x-ray microscopy, and radiation cell biology. Second there are the programs that are ultimately targeted at in-vivo applications. The present status of synchrotron coronary angiography, bronchography, multiple energy computed tomography, mammography and radiation therapy programs at laboratories around the world is reviewed.

    Full Text Available Allergic bronchopulmonary aspergillosis (ABPA is the best-known allergic manifestation of Aspergillus-related hypersensitivity pulmonary disorders. Most patients present with poorly controlled asthma, and the diagnosis can be made on the basis of a combination of clinical, immunological, and radiological findings. The chest radiographic findings are generally nonspecific, although the manifestations of mucoid impaction of the bronchi suggest a diagnosis of ABPA. High-resolution CT scan (HRCT of the chest has replaced bronchography as the initial investigation of choice in ABPA. HRCT of the chest can be normal in almost one-third of the patients, and at this stage it is referred to as serologic ABPA (ABPA-S. The importance of central bronchiectasis (CB as a specific finding in ABPA is debatable, as almost 40% of the lobes are involved by peripheral bronchiectasis. High-attenuation mucus (HAM, encountered in 20% of patients with ABPA, is pathognomonic of ABPA. ABPA should be classified based on the presence or absence of HAM as ABPA-S (mild, ABPA-CB (moderate, and ABPA-CB-HAM (severe, as this classification not only reflects immunological severity but also predicts the risk of recurrent relapses.

    The coherent and monochromatic x-ray beams available at the synchrotron radiation (SR) laboratories are ideal tools for the development and the initial application of new imaging techniques. In the present paper the history of the clinical studies in k-edge subtraction imaging with SR is summarized, including coronary angiography and bronchography. The results of the recent trial in phase-contrast mammography at Elettra (Trieste, Italy) are discussed, in order to assess the clinical impact of the new imaging modality and the potential interest in its translation to clinical practice. The direct measurement of linear attenuation coefficient obtained during the SR mammography trial is also discussed. The new program of phase-contrast breast CT under development at Elettra is presented. Recently, 3D breast imaging (tomosynthesis and cone beam breast CT) has been introduced in clinical practice with significant improvement in diagnostic accuracy. The aim of this research is to study the contribution of the phase-contrast to the image quality of breast CT. Increasing the image quality of the x-ray medical images at the level of the results obtained at the SR laboratories is highly desirable, hence the promising techniques for the translation of the phase-contrast imaging to the hospitals are briefly discussed.

    In the relatively short time that synchrotrons have been available to the scientific community, their characteristic beams of UV and X-ray radiation have been applied to virtually all areas of medical science which use ionizing radiation. The ability to tune intense monochromatic beams over wide energy ranges clearly differentiates these sources from standard clinical and research tools. The tunable spectrum, high intrinsic collimation of the beams, polarization and intensity of the beams make possible in-vitro and in-vivo research and therapeutic programs not otherwise possible. From the beginning of research operation at the National Synchrotron Light Source (NSLS), many programs have been carrying out basic biomedical research. At first, the research was limited to in-vitro programs such as the x-ray microscope, circular dichroism, XAFS, protein crystallography, micro-tomography and fluorescence analysis. Later, as the coronary angiography program made plans to move its experimental phase from SSRL to the NSLS, it became clear that other in-vivo projects could also be carried out at the synchrotron. The development of SMERF (Synchrotron Medical Research Facility) on beamline X17 became the home not only for angiography but also for the MECT (Multiple Energy Computed Tomography) project for cerebral and vascular imaging. The high energy spectrum on X17 is necessary for the MRT (Microplanar Radiation Therapy) experiments. Experience with these programs and the existence of the Medical Programs Group at the NSLS led to the development of a program in synchrotron based mammography. A recent adaptation of the angiography hardware has made it possible to image human lungs (bronchography). Fig. 1 schematically depicts the broad range of active programs at the NSLS.
