摘要:
目的:探讨多层螺旋CT(multi-slice spiral CT, MSCT)量化冠状动脉钙化的临床价值.方法:对41例临床可疑冠心病患者进行MSCT冠脉成像及其钙化的1化分析，并与选择性冠状动脉造形(CAG)进行对照。结果:MSCT对冠状动脉钙化显示清晰;MSCT冠状动脉造形(multi-slice spiral CT coronary angiography,MSCTCA)对冠状动脉各分支显示良好，其狭窄程度与冠脉造形一致。结论:MSCT可作为冠心病普查和冠脉术后复查的较好方法。
Abstract:
AIM:To explore the clinical value of multi-slice CT in the quantifative evaluation of coronary artery calcification. METHODS; A multi-slice CT system with 4 simultaneously acquired slices and a rotation time of 0. 5 sec was used (Siemens somatom sensation 4). A total of 41 patients with confirmed or suspected CAD (coronary arteries disease)underwent MSCT and MSCTCA. They were compared with quantitative coronary angiography. RESULTS:The coronary arteries calcium could be visualized by MSCT. MSCTCA showed a high diagnostic accuracy in the detection and quantification of coronary lesion. the results were identical with quantitative coronary artery angiography(CAG). CONCLUSION:MSCT was simple，reliable，non-invasive，low risk,comfortable and cheap.It has the potential to rule out CAD,to facilitate the evalution of pre- and post-operative cardiovascular situation,coronary artery calcifications creening and so on.
