title: Clinical situations in which coronary CT angiography confers superior diagnostic information compared with coronary angiography.
abstract: In this review, we aimed to outline the clinical and pathological conditions for     which multidetector computed tomography coronary angiography (MDCT-CA) should be     the preferred method because of its advantages over conventional coronary     angiography (CCA). A consistent body of literature suggests that MDCT-CA is more     than just complementary to CCA and that it provides more valuable diagnostic     information in certain clinical situations, such as complex coronary artery     variations, aorto-ostial lesions, follow-up of bypass grafts, myocardial     bridging, coronary artery fistulas, aortic and coronary artery dissections, and     cases in which the coronary ostia cannot be cannulated by a catheter because of     massive atherosclerosis or extremely tortuous vascular structures.
