Figure 2 A High-Grade Stenosis in the Midpart of the RCA

Conventional angiography image and corresponding volume-rendered dual source computed tomography scanner image (colored image) in a 68-year-old man presenting with unstable coronary artery disease. Mean heart rate during scanning was 66 beats/min. The arrow indicates a high-grade stenosis in the midpart of the right coronary artery (RCA). The arrowheads in the curved multiplanar reconstruction image (bottom) indicate cross sections proximal, within, and distal from the occlusion.
