The motion artifacts of the thoracic aorta and the supraaortic vessels were significantly reduced in the electrocardiogram (ECG)-gated data acquisition. This positive effect of ECG synchronization is more pronounced in the region of the ascending aorta, aortic arch, and proximal descending aorta.Keywords: ECG-gated, MDCT 64-slice, chest vascular disease
