Abstract： 目的以普通冠状动脉导管造影为参照,评价屏气三维快速平衡稳态进动(FIESTA)序列对冠状动脉狭窄的显示效能.方法连续33例患者在冠状动脉导管造影检查的3周内接受冠状动脉MR血管成像(CMRA)检查,将冠状动脉狭窄划分成0%、0%～25%、25%～50%、50%～75%, 75%～100%共5个级别,对两者判断的结果逐段进行比较.结果 CMRA对区分>50%和 <50%狭窄的准确度、敏感度和特异度分别为84.3%、84.8%和84.1%,阴性预测值为92.3%;对区分50%～75%与75%～100%狭窄的准确度、敏感度和特异度均为61.5%.结论屏气三维FIESTA冠状动脉成像序列对具有血流动力学意义狭窄的排除具有一定的实用价值,但是更细致的分级受限.
