OBJECTIVE Dual-source CT has excellent temporal resolution and allows good visualization of coronary vessels without heart rate control. Our aim was to evaluate the diagnostic performance of dual-source CT in the evaluation of coronary stent patency to determine whether the good temporal resolution would improve visualization of stents.

Double left anterior descending coronary artery arising from the left and right coronary arteries is one of the rarest of coronary anomalies. In this report, we present a case of double left anterior descending coronary artery with one originating from the left main stem and the second one originating from the same ostium with the right coronary artery,(More)
PURPOSE To prospectively evaluate the sensitivity and specificity of dual-source CT for significant coronary stenosis (>50% narrowing) in patients with atrial fibrillation (AF), by using conventional coronary angiography as the reference standard. MATERIALS AND METHODS Institutional Review Board approval and informed consent were obtained. Fifteen(More)
PURPOSE To prospectively assess the diagnostic performance of 64-section multidetector computed tomography (CT) for the evaluation of coronary stent stenosis and occlusion by using conventional coronary angiography as the reference standard. MATERIALS AND METHODS Institutional review board approval and informed consent were obtained. Thirty patients (27(More)
PURPOSE To prospectively evaluate the diagnostic performance of 64-section multidetector computed tomography (MDCT) to detect significant coronary artery stenosis using conventional coronary angiography (CCA) as the reference standard. MATERIALS AND METHODS Institutional Review Board approval and informed consent were obtained. In this prospective study,(More)

BACKGROUND A noninvasive imaging modality is desirable for the evaluation of coronary bypass graft stenosis and occlusion. PURPOSE To prospectively evaluate the effectiveness of 64-detector-row computed tomography (DCT) for the assessment of coronary bypass grafts. MATERIAL AND METHODS Forty-two patients (35 male, seven female, mean age 66.3 years) with(More)
PURPOSE Coronary artery calcium (CAC) is a specific indicator of and an independent risk factor for atherosclerosis; however, calcium scoring may miss noncalcified plaques, which may have clinical importance. The aim of this study was both to identify the presence and extent of coronary plaques during computed tomography coronary angiography (CTCA) in(More)
Coronary artery fistula is a rare congenital anomaly in which a communication is present between a cardiac chamber or another vascular structure. In this paper, we describe a 52-year-old asymptomatic male patient with a right coronary artery to left ventricle fistula. We demonstrate the effectiveness of 64-MDCT (Multi-detector row computed tomography) in(More)
