Methods for quantitative assessment of the skeleton are relevant to the understanding of growth and development during normal childhood and studying the effect of disease and therapy in children with chronic diseases. Dual energy x-ray absorptiometry (DXA) is currently the most widely available and utilised technique in adults and children. The strengths of DXA are: • The technology is widely a...

Over the past decade, quantitation of cardiac single-photon emission computed tomography (SPECT) data, once limited to perfusion assessment, has been extended to global and regional function assessment for both the left and the right ventricle, as well as to measurement of additional cardiac parameters of diagnostic and prognostic interest. A number of commercially available quantitative algori...

conclusion there is still excessive unjustified concern of pte in less trained physicians leading to excessive diagnostic work-up. loyalty to the existing guideline for management of suspected pte in educational hospitals and supervision of attending physicians could prevent overuse of ctpa. results during a 6-month period, 82 patients who underwent ctpa were included. the prevalence of pte was...

background: proper rotation of components in total knee arthroplasty (tka) will largely affect the postoperative outcome. ethnical variation may affect rotational profile. we aimed to evaluate distal femur rotation in iranian population using transepicondylar axes.   methods : from a total of 450 knee ct scans and via consecutive sampling, 150 qualified subjects with normal lower extremities al...

Background: This study assessed the optimal timing of computed tomography for detection of metastatic disease in locoregional lymph nodes in patients with rectal cancer who have undergone chemoradiotherapy. Materials and Methods: This observational retrospective study was performed in a single institution. All patients with locally advanced rectal cancer treated with chemoradiotherapy, followed...
