introduction: chest x-ray (cxr) is the simplest diagnostic tool of community acquired pneumonia (cap), but it has some limitation. therefore, the aim of this study is comparing the diagnostic accuracy of cxr and chest ultrasonography (cus) in detection of cap. methods: in the present study, a consecutive sample of suspected patients with cap was underwent cus, cxr, and chest computed tomography...

objectives to evaluate morphologic variations at the aortic isthmus with particular attention to ductus diverticulum, a mimicker of traumatic pseudoaneurysm, and to describe differences using computed tomography (ct) images. patients and methods from december 2013 to december 2014, patients who underwent a chest ct examination after blunt trauma at our emergency department were included. aortic...

the possibility of abnormal avf was considered and it was confirmed on contrast-enhanced computed tomography (ct), inferring that this modality is not only fast and non-invasive, but also accurate in detecting vascular abnormalities. herein, we report a 42-year-old woman with congenital avf between the external carotid artery and external jugular vein, presenting with palpitation and dyspnea. t...

the reversed halo sign (rhs) may sometimes be seen in patients with cryptogenic organizing pneumonia (cop), but is rarely associated with other diseases. herein, we present a case of a 21-year-old woman with chronic eosinophilic pneumonia, with high resolution computed tomography (hrct) finding of rhs. this is an unusual and rare presentation of chronic eosinophilic pneumonia.

background malignant pleural mesothelioma (mpm) is an uncommon neoplasm. mpm occurs more frequently in patients born or living in certain villages of turkey. objectives we aimed to review radiological findings of mpm. patients and methods we reviewed the ct findings in 219 biopsy-proven mpm patients admitted to our clinic between 1993 and 2008. results the most common ct findings included pleur...

pulmonary adenocarcinoma is one of the major types of lung cancers in which metastasis is not uncommon. hereby, we report a case of pulmonary adenocarcinoma with multiple muscular, cutaneous, pancreatic and peritoneal metastases. actually, all these features occurring in one patient makes it an extraordinary case. a rare anatomic variation, double inferior vena cava (ivcs), was another rare man...

hydatid disease is a parasitic infestation caused by the larval form of echinococcus gronulosus and it remains a considerable public health problem in several mediterranean countries such as iran. liver is the most common site of involvement. lungs are the second most common sites of hematogeneous spread in adults and are probably the most common sites in children (15% - 25% of cases). primary ...

X-ray computed tomography (CT) can reveal the internal details of objects in three dimensions non-destructively. In this Primer, we outline basic principles CT and describe ways which a scan be acquired using tubes synchrotron sources, including different possible contrast modes that exploited. We explain process computationally reconstructing three-dimensional (3D) images from 2D radiographs h...

X-ray computed tomography (CT), introduced into clinical practice in 1972, was the first of the modern slice-imaging modalities. To reconstruct images mathematically from measured data and to display and to archive them in digital form was a novelty then and is commonplace today. CT has shown a steady upward trend with respect to technology, performance and clinical use independent of predictio...
