A series of 186 patients with blunt chest trauma was studied with transthoracic ultrasonography to diagnose pneumothorax and to evaluate its size and location. The results were compared with bedside chest radiography and spiral CT scan. The prevalence of pneumothorax on CT scan was 56/186 (30.1%). Pneumothorax was proven on radiography in 30/56 cases without false positive results: "radiographi...

PURPOSE To evaluate the image quality and radiation dose of combined heart, head, and neck CT angiography (CTA) using prospectively electrocardiography (ECG)-triggered high-pitch spiral scan protocol, compared with single coronary CTA. MATERIALS AND METHODS 151 consecutive patients were prospectively included and randomly divided into three groups. Group 1 (n = 47) underwent combined heart, n...

One strategy was compression ultrasonography, followed by anticoagulation in case of positive results (high probability ventilation-perfusion (VQ) scans) or by VQ scan or spiral computed tomography (CT) in case of negative results. Low probability VQ scans resulted in no treatment, whereas high probability VQ scans resulted in anticoagulation. Intermediate tests were followed by a second test (...

OBJECTIVES To assess the capability of spiral computed tomography (CT) scan in preoperative evaluation of colorectal carcinoma (CRC). METHODS A cross sectional study on 52 patients with recent histopathologic diagnosis of CRC was conducted over a period of one year at the Aga Khan University Hospital, Karachi. All these patients underwent spiral CT with oral and intravenous contrast administr...

introduction: pulmonary embolism (pe) is a common lethal disease that its clinical symptoms may be seen in many other diseases. computed tomography pulmonary angiography (ctpa) is a valuable diagnostic modality for detection of pe. in addition, it can accurately detect the other diseases with clinical symptoms similar to pe. the aim of this study is to evaluate the frequency of pe and nonemboli...

   A 36-year-old woman with right upper quadrant abdominal pain since three months previously and no other significant medical history was referred for evaluation of an abdominal mass. Upon clinical examination, a large palpable mass in the mid -upper abdominal area was noted. Abdominal ultrasound and spiral CT-scan showed a large hepatic mass in the left liver lobe. ...

conclusions our study shows in terms of figures that measurements of features of the temporal bone made from spiral ct scan images and those directly obtained during surgery are similar to an adequate extent. results twenty cases were included. in the three measurements performed in this study, only the first parameter (distance between the canal and the sigmoid sinus) was significantly differe...
