Abstract Background: Given the different prevalence of accessory spleen in previous studies and no information about its rate of detection and also its known side effects, this study was designed to determine the prevalence and associated factors of accessory spleen among patients referred to a CT scan center in Tehran between 2008 and 2010. Methods: In this cross- sectional study, all pat...
There is still considerable debate about the optimal diagnostic imaging modality for acute pulmonary embolism. If imaging is deemed necessary from an initial clinical evaluation such as d-dimer testing, options include nuclear medicine scanning, catheter pulmonary angiography, and spiral CT. In many institutions, spiral CT is becoming established as the first-line imaging test in daily clinical...
Although 3D-CT angiography provides valuable anatomic information regarding lesion and their surrounding vessels and bony structures, it cannot demonstrate lesions, arteries, and veins, separately. The separate demonstration of arterial-phase 3D-CT angiography (3D-CT arteriography) and venous-phase 3D-CT angiography (3D-CT venography) will facilitate the understanding of the vascular anatomy wi...
84 ● M a r t 2 0 0 1 C omputed tomographic angiography (CTA) is a technique that has evolved in a rapidly changing interplay of hardware and software advances. CT scan times are becoming ever shorter, now allowing imaging of larger segments of arterial anatomy during circulation of the intravenous bolus of contrast material. Multidetector (or multislice) CT is the most recent dramatic advance t...
Traumatic diaphragmatic rupture remains a diagnostic challenge for both radiologists and surgeons. In recent years, multidetector CT has markedly improved the diagnosis of diaphragmatic injury in polytrauma patients. Herein, we describe two cases of subacute presentation of traumatic diaphragmatic rupture from a penetrating rib fracture and subsequent intrathoracic herniation of omental fat, re...
BACKGROUND AND PURPOSE Recent studies have investigated plaque morphology to determine patients who are at high risk of carotid atherosclerosis. In this study, we investigated whether a difference in dynamic enhancement pattern in plaque components could be useful to assess plaque stability with multidetector CT angiography. METHODS Fifty-nine lesions with moderate to severe carotid atheroscl...
We present the computed tomography (CT) imaging findings of a 44-year-old male with incidentally discovered right adrenal hemangioma displaying imaging pattern of nonadenomatous pattern, associated with multiple hepatic hemangiomata using 64-slice multidetector scanner with reviewing published CT imaging findings with short review of the literature.
