The value of 64-slice spiral CT coronary angiography in diagnosis of myocardial bridge

目的探讨64排螺旋CT冠状动脉成像对心肌桥的诊断价值。方法回顾性分析行64排螺旋CT冠状动脉成像患者108例的影像资料,统计心肌桥的检出率及发生部位。结果 64排螺旋CT冠状动脉成像发现心肌桥-壁冠状动脉(MB-MCA)26例,共28处,其中发生于左前降支的心肌桥-壁冠状动脉18处,占64.3%,为最常见发生部位。结论 64排螺旋CT冠状动脉成像是一种无创性、准确诊断心肌桥的重要检查方法。

Objective To explore the value of coronary angiography with 64-slice Spiral CT in diagnosing myocardial bridge. Methods A retrospective analysis was carried out in 108 patients with image data of 64-slice spiral CT coronary angiography,statistics of the myocardial bridge detection rate and location. Results A total of 28 myocardial bridge in 26 subjects were identified, and 18 of them were in the site of left anterior descending branch ,the rate was 64.3%. Conclusion 64-slice Spiral CT coronary angiography is an accurate and non-invasive technique in the diagnosis of myocardial bridge.
