摘要:
冠状动脉CT血管造影（CTA）目前已广泛应用于临床, 但心律失常患者一直是此项技术的瓶颈。由于传统的螺旋CT及双源CT的技术限制，对心律失常患者扫描过程中往往因为心脏运动不规律，导致图像不连续。心电编辑技术可解决部分此类问题，改善图像的质量，提高诊断的灵敏度。宽探测器CT（如320排螺旋CT）在低心率条件下可在一个心动周期成像，能消除此类伪影，但时间分辨力尚待提高。
Abstract:
Coronary computed tomography angiography (CTA) has been widely applied in clinical practice, but arrhythmia has always been the bottleneck of the technology. Limited by the technological problems of multidetector spiral CT and dual-source CT, images always discontinue for the irregular cardiac rhythm. Electrocardiograph editing technology can improve image quality and diagnostic sensitivity. Wide-detector CT can rebuild the images by a single heartbeat in the case of low heart rate, which helps to eliminate artifacts, but its temporal resolution needs to be improved.
