Figure 1 (A) Multislice computed tomography: normal aspect of the proximal left and right coronary arteries. Note some partial volume effect in the proximal right coronary artery (RCA). (B) Same patient, with conventional coronary angiography: normal aspect of the proximal left and right coronary arteries. Ao = aorta; Cx = circumflex artery; LAD = left anterior descending artery.

Figure 2 (A) Multislice computed tomography: diffuse wall thickening of the left main coronary artery and left anterior descending (LAD) artery, with some calcifications limited to small, calcified, parietal nodules (white arrows) and non-calcified plaques (black arrows). Note some irregularity of the proximal LAD and diffuse narrowing of the distal LAD. There was no significant coronary stenosis. (B) Same patient, with conventional coronary angiography: normal aspect of the circumflex artery (Cx); diffuse wall thickening of the LAD was seen as diffuse narrowing of the coronary lumen. Ao = aorta.

Figure 3 (A) Multislice computed tomography: severe stenosis of the first segment of the circumflex artery (Cx) associated with distal stenosis in the circumflex artery (arrows). (B) Same patient, with conventional coronary angiography: severe stenosis of the first segment of the circumflex artery associated with distal stenosis in the circumflex artery (arrows). Ao = aorta; LAD = left anterior descending artery.
