S.From all the patients with MB-MCA and whose MCA were encased by the myocardium completely,30 patients were choosed randomly,their datasets were reconstructed seriatim by every 5%R-R interval,the whole cardiac cycle were reconstructed by 20 phases,the diameter of the mural coronary arteries of every phase was reviewed and measured,the phases were found out where the diameters were maximal and minimal,the systolic compression rate was calculated,Pearson correlation analysis was used to analyze the relation between length,depth,and degree of systolic compression of the mural coronary artery.

s表示。在所有存在MB-MCA并且MCA被心肌完全包饶的病例图像中，随机抽取30例图像的数据，以每隔5%R-R间期为一个重建时相，对每个病例0.100%整个心动周期分20个期相进行重建，观察并测量MCA在整个心动周期中管径的变化，探索管径最大和最小时的时相显示规律，计算MCA最大狭窄程度，应用Pearson相关统计分析MCA狭窄程度与MB的长度及厚度之间的相关关系。
