320-slice CT can acquire images of the whole heart with only a single scan because of its wide coverage (0.5 mm x 320-slice =16 cm) to the through plane.Therefore, 320-slice CT makes it possible to scan whole heart images in subjects with arrhythmias or those with heart rate irregularities without banding artifacts and stair-step artifacts.We evaluated coronary arterial image quality on 320-slice CT in 92 subjects with chronic atrial fibrillation (CAf) vs.normal sinus rhythm (NSR) and by 320-slice CT, the overall length of visualized coronary arteries, motion artifact-free length,and image quality showed values equal to or slightly lower in CAfthan in NSR, but the absolute values were quite acceptable in both groups.
