    【摘要】 目的：探讨64排螺旋CT冠脉成像检查对心肌桥-壁冠状动脉(MB-MCA)的诊断价值。方法：回顾性统计分析2018年1月-2020年1月本院收治的80例先后行64排螺旋CT冠脉成像及冠脉造影检查患者的临床影像学资料，观察MB-MCA的发生情况。结果：本组80例病例中，64排螺旋CT冠脉成像检出MB-MCA 34例，64处，检出率42.5%。冠脉造影检查出MB-MCA 32例，57处，检出率40.0%。64排螺旋CT冠脉成像与冠脉造影共同显示53处MB-MCA一致，以冠脉造影检查为“金标准”，64排螺旋CT冠脉成像检出MB-MCA的准确度为93.0%(53/57)。结论：64排螺旋CT冠脉成像检查可作为诊断MB-MCA的一项简便、有效且无创的检查，在临床上具有一定的推广价值。

    [Abstract] Objective： To investigate the diagnostic value of 64-slice spiral CT coronary angiography in myocardial bridge and muralcoronary artery (MB-MCA). Method： The clinical imaging data of 80 patients who undergoing 64-slice spiral CT coronary angiography and coronary angiography from January 2018 to January 2020 were retrospectively analyzed， and the occurrence of MB-MCA was observed. Result： Among 80 cases in our series， 34 cases of MB-MCA were detected by 64-slice spiral CT coronary angiography， 64 cases， the detection rate was 42.5%. 32 cases of MB-MCA were detected by coronary angiography ......
