多排螺旋CT冠状动脉成像的临床进展

The Clinical Development of Multi-Slice Spiral CT Coronary Artery Imaging

近年来,随着多排螺旋CT设备研究的不断深入,多排螺旋CT冠状动脉成像(Multislice Spiral CT Coromary Angiography,MSCTCA)在诊断冠状动脉粥样硬化性心脏病(Coronary Artery Disease,CAD)中得以广泛应用,因影像技术不断进步和发展,促使MSCTCA检查准确性有很大程度的提升,同时MSCTCA检查在预测CAD病程进展与心血管事件中具有重要作用此项检查已成为筛查CAD有效、安全的检查方式。MSCTA对冠状动脉狭窄及其引发的病变能够作出较高的诊断指导,对评价CAD患者的狭窄程度以及斑块的稳定性,指导临床治疗以及预后评估提供可靠的影像学依据。即便MSCTCA在临床诊断还存在一定的局限性,但随着256排、320排螺旋CT、双源螺旋CT的出现以及光谱CT不断研发进展,大大弥补了目前MSCT的技术缺陷,并且进一步提升影像质量。故就MSCTCA的临床进展作一综述。

In recent years,with the development of multi-slice spiral CT equipment,multi-slice spiral CT coronary angiography(MSCTCA)has been widely used in the diagnosis of coronary artery disease(CAD),at the same time,MSCTCA examination plays an important role in predicting the progress of CAD and cardiovascular events.This examination has become an effective and safe way to screen CAD.MSCTA can effectively evaluate the degree of coronary stenosis and plaque stability in patients with coronary heart disease,and provide reliable imaging basis for clinical treatment and prognosis evaluation of patients with coronary heart disease.Although MSCTCA still has some limitations in clinical diagnosis,with the emergence of 256 slice,320 slice spiral CT,dual source spiral CT and the continuous progress of spectral CT,it makes up for the defects of multi-slice CT,so as to further improve the imaging quality.Therefore,this article reviews the clinical progress of MSCTCA.
