摘要
目的:分析壁血管-心肌桥(MB-MCA)在16层螺旋CT(MSCT)冠状动脉(简称冠脉)成像的图像特征。方法:通过回顾性分析经MSCT检查临床疑似冠心病(CHD)患者300例中检出的67例MB-MCA影像学特点,并判断MB-MCA与动脉粥样硬化的关系。结果:MB-MCA在MSCT的检出率为22.3%,最常出现在左前降支,壁血管平均长度为13.1 mm,心肌桥厚度为1.6 mm,合并临近血管动脉粥样硬化为29.9%。结论:MSCT可用于判断MB-MCA的结构特点;MB-MCA与动脉粥样硬化有相关性。
Objective： To study the imaging manifestation of MB - MCA of multislice spiral computed tomography angiography in coronary artery. Methods： A restrospective analysis was made on the data of the MSCT imaging manifestation of 67 patients with MB - MCA out of 300 patients suspected as with coronary artery dis- ease（CHD） underwent 16- sclice computed tomography in coronary artery. Results： Positive rate of MB- MCA was 22.3 %, the left anterior coronary artery mostly has been involved, the length of MCA was 13.1 mm, the thickness of MB was 1.6 mm, coronary atherosclerosis was found in 20 of the 67 patients（29.9 % ）. Conclusion： 16 - slice CT can be used to confirm the presence of MB - MCA, coronary atherosclerosis is significantly correlated with MB - MCA.
