| 摘 要： | 目的 探讨320排动态容积CT(320-slice dynamic volume CT,320-DVCT)评价壁冠状动脉-心肌桥(MCA-MB)的形态学特征、准确性及其临床应用价值.方法 85例可疑冠心病住院患者行心脏320-DVCT并冠脉CTA,同期行冠状动脉造影术(CAG),分析MCA-MB影像学特点.结果 320-DVCT对MCA-MB的检出率为30.6%,其中82.4%出现在左前降支中、远段,平均长度为(13.38±5.06)mm,MB平均厚度为(3.61±2.53)mm.MCA-MB合并邻近血管动脉粥样硬化发生率为96.2%.CAG的MCA-MB的检出率为8.2%,320-DVCT对MCA-MB的检出率明显高于CAG.结论 320-DVCT可准确判断MCA-MB的结构特点;临床怀疑冠心病者MCA-MB与动脉粥样硬化有一定相关性.320-DVCT是一种无创、准确诊断和评价MCA-MB的方法.

| Abstract: | Objective To evaluate the morphological assessment,accuracy and clinical significance of 320-slice dynamic volume CT(320-DVCT) in diagnosis of mural coronary artery-myocardial bridges(MCA-MB).Meth-ods The 320-slice DVCT scan and coronary angiography(CAG) were performed in 85 patients suspected of coronary artery disease(CAD) for evaluation of the efficacy of DVCT in MCA-MB diagnosis.Results The detection rate of MCA-MB with 320-slice DVCT was 30.6%,among which 82.4% were located in middle and distal segment... |
