摘　　要：目的探讨64层螺旋CT冠状动脉成像技术对心肌桥的诊断价值.方法对1655例成人冠状动脉CT血管成像(CTA)资料进行回顾性分析、总结,并与国内、外文献比较。结果1655例完整CT冠状动脉成像结果中,共检出成人心肌桥238例,检出率为14.38%,共检出肌桥259段,其中前降支中段238段,前降支远段7段,前降支近段4段,右冠中段3段,CRX中段3段,其他冠状动脉节段4段.结论64层螺旋CT冠状动脉成像是诊断心肌桥可靠的影像学方法.Objective To access the value of 64 multi-slice CT coronary angiography in diagnosing myocardial bridge (MB).Methods 1655 patients undergone CT coronary angiography (CTCA) were reviewed for this study.Results In consecutive 1655 patients,CTCA identified 238(14.4%) patients with MB and detected 259 MB sections,including 238 MB sections in the middle segment of LAD, 7 sections in the distal segment of LAD,4 sections in the proximal segment of LAD,3 sections in the middle segment of RCA, 3 sections in the middle segment of LCX,and 4 sections located in the other coronary artery segments.Conclusions 64-slice CTCA was an effective and accurate method in diagnosing myocardial bridge.
