The study of fossils permits the reconstruction of past life on our planet and enhances our understanding of evolutionary processes. However, many fossils are difficult to recognize, being encased in a lithified matrix whose tedious removal is required before examination is possible. The authors describe the use of multidetector computed tomography (CT) in locating, identifying, and examining f...

UNLABELLED We present a rare complex variation of the inferior vena cava and internal iliac veins demonstrated by a multidetector computed tomography. It was shown that patient had double inferior vena cava with azygos continuation of the right inferior vena cava, retroaortic left renal vein and the left and right internal iliac veins converged and drained to the right external iliac vein throu...

background: paratracheal air cysts (pacs) are extraluminal collections of air mostly located adjacent to the right of the trachea at the level of the thoracic inlet. although, pacs are usually asymptomatic, the lesions do occasionally cause complications such as chronic cough, difficult intubation, and right-sided recurrent laryngeal nerve palsy. the purpose of the present study was to demonstr...

conclusion we conclude that coronary calcium scoring provided useful information in the management of patients. in cacs less than 100, it has a npv of 87% in excluding significant stenosis in patients with the risk of cad but it does not have enough diagnostic accuracy for surely excluding coronary stenosis, so we should perform a combination of cacs and coronary ct angiography for patients. re...

PURPOSE To directly compare the sensitivity of 64-section multidetector computed tomography (CT) with that of 1.5-T magnetic resonance (MR) imaging in the depiction and measurement of heterogeneous 7-8-week-old microinfarcts and the quantification of regional left ventricular (LV) function and perfusion in the territory of coronary intervention in a swine model. MATERIALS AND METHODS Approval...

Advances in 64-row multidetector computed tomography have provided noninvasive imaging of coronary arteries. The aim of this study was to evaluate the prevalence of coronary artery anomalies in Iranian symptomatic patients and to determine the presence of anomalies resulting in myocardial ischaemia without atherosclerotic plaque. This study was carried out in Tabriz University of medical scienc...

Background: The most often fractured bone among the tarsal bones is calcaneum. first assessment of suspected calcaneum fracture conventional radiography. modern calcaneal fractures mainly based on multidetector computed tomography, because its three-dimensional nature and Volume rendering techniques. objective this study was to compare diagnostic value Multidetector CT with Conventional radiogr...

PURPOSE To evaluate multidetector computed tomographic (CT) images to investigate the prevalence, morphology, natural course, and prognostic effect of intramural blood pools (IBPs) in patients with acute intramural hematoma (IMH). MATERIALS AND METHODS Institutional review board approval and written informed consent were obtained. Sixty-five patients (41 men; mean age, 65.9 years ± 11.3 [stan...

OBJECTIVES This study aimed to evaluate the role of multidetector computed tomography angiography in diagnosing patients with pulmonary sequestration. METHODS We retrospectively analyzed the computed tomography studies and clinical materials of 43 patients who had undergone preoperative multidetector computed tomography angiography in our hospital and had pathologically proven pulmonary seque...

conclusion our results indicate that dsct coronary angiography provides high diagnostic accuracy for the evaluation of cad patients during daily routine practice of a referral cardiovascular setting. background there are numerous studies that address the diagnostic value of dual-source computed tomography (dsct) as an alternative to conventional coronary angiography (cca). however, the benefit ...
