多层螺旋CT在急性冠状动脉综合征诊断中的应用

Efficacy of multislice computed tomography for the detection of acute coronary syndrome

急性冠状动脉综合征(ACS)是在动脉粥样硬化的基础上,斑块破裂、表面破损或裂纹引起血栓形成,导致冠状动脉不完全或完全闭塞,使心肌发生缺血或不同程度坏死的一组临床综合征。多层螺旋CT是一种新的无创性影像诊断技术,近年来临床已使用该技术检测冠状动脉狭窄和钙化,多层螺旋CT不仅可以评价冠状动脉狭窄或闭塞,还可以评价冠状动脉斑块的性质和心肌血流灌注情况。本文综述多层螺旋CT在ACS诊断中的作用。

Acute coronary syndrome（ACS） is a consequence of rupture of lipid-rich plaques and subsequent thromhus formation, which induces myocardial ischemia or infarction. Muhislice computed tomography （MSCT） is a new non-invasive diagnostic imaging technology.. The technology in recent years has been used in the detection of coronary artery stenosis and calcification. Not only can MSCT detect coronary stenosis or occlusion, but also evaluate myocardial perfusion and coronary, plaque nature of the situation. This article reviewes the application of MSCT in the diagnosis of ACS.
