多层螺旋CT检测冠状动脉钙化的临床应用进展

Clinical application of MSCT in coronary artery calcium detection

冠状动脉粥样硬化性心脏病是临床常见慢性疾病之一,而冠状动脉钙化是其重要标志。冠状动脉钙化特别是重度钙化病变,是引起手术即刻并发症及主要心血管不良事件的主要因素。因此,进行冠状动脉钙化评估具有重要的临床价值。多层螺旋CT技术(multi-slice CT,MSCT)是一种可对冠脉钙化斑块进行精确量化评估的非侵入性检查手段,近年来在临床上得到广泛应用。本文就利用MSCT进行冠状动脉钙化检测的方法与其他检测方法的优缺点比较及其临床意义等方面进行综述。

Coronary artery disease is one of the most common chronic diseases, and coronary artery calcification is an important marker of coronary atherosclerotic progress. Coronary artery calcium, especially severe calcified lesion, is a significant risk factor of immediate complications of surgery and major adverse cardiovascular events in early and late stages. Cardiac multi-slice CT scan is a non-invasive technique to detect the presence, location and extent of calcified plaque in coronary arteries. In this article, we review the utilization of multi-slice CT in detection of coronary calcification, especially in the capabilities and significance of calcium scoring. Moreover, the advantage and disadvantage of MSCT and other examinations in coronary artery calcification detection are also summarized.
