Figure 1

Magnetic resonance angiograms of the right coronary artery (RCA) in a single healthy volunteer obtained with three different sequences. A: The bright blood image shows good fat suppression and vessel conspicuity. B: High resolution sequence produces an image with clearly defined vessel borders, the contrast between blood and epicardial fat enables good identification of the RCA. Several structures can be identified in this image: the ostium and a portion of the RCA. RVOT = right ventricular outflow tract, Ao = aortic root, LV = left ventricle. C: Image acquired with black blood sequence shows a less clearly defined vessel border as compared to panel A and B. Note the suboptimal blood suppression proximally and in the distal segment.
