Abstract:
Objective To evaluate retrospectively ECG -gating for the coronary angiography with MSCT. Methods 15 patients were studied with a multislice spiral CT on retrospective ECG -gating,0.5s rotation, and cardial segment reconstruction algorithm. Nine phases were chosen to reconstruct images of coronary arteries. Results In the 230 coronary artery segments,213 (91%)were best visualized at 70%. And 15 (6.4%), 9 (3.8%), and 3 (1.3%) were optimal at 80%, 40% , and 5% of the cycle respectively. Conclusion The coronary arteries usually are best visualized at 70% image reconstruction window of the cardial cycle.
