| 摘 要： | 目的:探讨64层螺旋CT冠状动脉(冠脉)成像(64-slice CT coronary angiography, 64SCTCA)对心肌桥(MB)的诊断及其临床价值.方法:932例患者均行64SCTCA扫描,所有数据传至工作站进行重建和后处理,观察有无MB,测量MB的长度、厚度、壁冠脉(MC)狭窄程度等.对64SCTCA发现MB的病例均行冠脉造影(CAG)并与64SCTCA的结果进行对比.结果:932例患者经64SCTCA检出MB 356例,MB检出率为38.1%;而64SCTCA 检出的356例MB病例中经CAG仅检出MB 89例,MB检出率10.2%;两者比较差异有统计学意义(P<0.05).64SCTCA发现MB的平均长度及厚度分别为(9.4±5.6)mm、(5.9±4.3)mm,MC狭窄程度为(39±23)%;CAG与64SCTCA对MB的狭窄程度与长度比较, 差异亦有统计学意义(P<0.05).结论:64SCTCA对MB和MC清晰显示,有着特殊的临床价值.

| Abstract: | Objective:To assess the diagnostic and clinical value of 64-slice CT coronary angiography(64SCTCA) for evaluation of of myocardial bridge(MB) and mural coronary artery(MC).Method:The total of 932 patients underwent 64SCTCA.The CT data were reconstructed and post-processed in the work-station.All the cases with MB were submitted to coronarography(CAG) studies obsewing the exstance.The length,thickness of MB and the stenosis of MC.The results of CT and CAG were compared and analyzed in the end.Result:The 356 ... |
