CT Angiography: A closer look

Case 1
Patient with mild hyperlipidemia and atypical chest pain. Curved reconstructions of the left anterior descending coronary artery show just beyond its origin, a plaque [arrows] consisting largely of “soft” non-calcified (gray) material but with a small central calcification (white). These reconstructions and the dynamic 3D surface reconstruction demonstrate that the major branches of the left and right coronary artery systems are free of significant narrowing.
Case 2
Asymptomatic patient with pronounced hyperlipidemia and a strong family history of coronary artery disease. Curved reconstructions and a colored surface reconstruction of the left anterior descending coronary artery show, in addition to generalized mild irregular wall thickening and slightly arterial enlargement from early diffuse atherosclerosis, several calcified plaques [arrows] without significant narrowing.
Case 3
Patient with equivocal stress test results and atypical chest pain. Curved reconstructions of the left anterior descending coronary artery and a dynamic 3D surface reconstruction demonstrate a long, densely calcified atherosclerotic plaque [arrows] resulting in significant narrowing of the artery.
