ABSTRACT
Objective: To evalute the method's ability and limitations of Multi-slice CT coronary angiography.
Methods：A multi-slice CT system with 4 simultaneously acquired slices and 0.5sec rotation time is used (Siemens Somatom plus 4 Volume Zoom). Total of 80 patients without diagnosed coronary disease underwent cardiac CT. Five 3D reconstruction methods (VR, MIP, MPR, SSD, CTVE) were used.
Results：90% of the coronary arteries could be visualized over long segments, on average, 2/3of the main coronary arteries length can be visualized free of motion artifacts.
Conclusion：This method is simple, reliable, non-invasive, low risk, comfortable, and non-expensive cardiac imaging modality. It has the potential to rule out CAD, permits evaluation of pre-and postoperative cardiovascular situation,coronary artery calcification screening and so on.
Key words：Multi-slice Computed Tomography; Coronary; Angiography
随着CT及MRI的兴起，心血管诊断手段愈来愈趋向无创或少创，对临床发展起到了举足轻重的作用，多层螺旋CT可以进行亚秒扫描，在冠状动脉诊断检查方面有了突破性进展。本研究的目的在于探讨多层螺旋CT对冠状动脉的显示能力。究竟这种新兴的无创的冠状动脉检查手段能否显示冠状动脉，能显示哪几支冠状动脉，能否显示冠状动脉全长，这是大家最为关心的问题，也是我们研究的重点。 |
