摘要 目的探讨双能量CT(dual energy computed tomography,DECT)一站式冠状动脉联合心肌灌注扫描技术的应用价值。方法采用双源CT(somatom definition,Siemens,Germany)双能量心脏扫描模式对28例患者行一站式DECT检查,将扫描数据分别进行冠状动脉形态学和心肌灌注碘分布图后处理,冠状动脉形态学分析根据冠状动脉疾病报告与数据系统(CAD-RADS)进行狭窄程度分级,心肌灌注分析根据美国心脏病协会推荐的左心室17段法,在左心室短轴、长轴及四腔心平面进行分析。结果28例患者均成功完成双能量冠脉CT检查,无不良反应。冠状动脉形态学分析0级3例(10.7%),1级5例(17.9%),3级10例(35.7%),4级7例(25.0%),5级2例(7.1%),搭桥1例(3.6%),心肌灌注共分析28例患者476段心肌,灌注缺损心肌共431段(90.5%),无灌注缺损45段(9.5%)。结论双能量CT一站式冠状动脉联合心肌灌注扫描可以同时显示冠状动脉形态学和心肌灌注情况,具有临床应用价值。
