Fig. 1B —63-year-old man presenting to emergency department with 10
minutes of exercise-induced substernal chest pain radiating to his left arm
2.5 hours ago. Initial troponin and creatine kinase, myocardial bound tests
were negative, and ECG showed T-wave inversions in V1 to V3; otherwise
unremarkable ECG. 64-MDCT was performed 3 hours after emergency department
presentation. RCA = right coronary artery, LAD = left anterior descending
artery, LCX = left circumflex coronary artery, PDA = posterior descending
artery. Curved multiplanar reconstruction along centerline of LAD artery shows
regular contrast enhancement of all LAD segments with scattered small
calcified plaques but no significant luminal narrowing.
