目的 利用256层螺旋CT冠状动脉成像探讨心肌桥-壁冠状动脉(MB-MCA)的形态学特征及多时相重建量化分析MCA在心脏收缩期和舒张期的变化.方法 收集自2010年6月至2011年4月来北京中日友好医院放射科进行冠状动脉成像检查的861例患者的影像资料.由两位有经验的放射科医师独立分析患者的影像资料,当两者意见取得一致时,MB-MCA的诊断成立.描述MB-MCA分布,并在心脏收缩期和舒张期分别记录位于LAD的MB-MCA的长度、厚度以及血管直径,由此可以计算其在收缩期及舒张期的变化情况.结果 在861例患者中有131( 15.2％)例存在150段MB-MCA,其中99 (66.0％)段MB-MCA位于LAD中段,剩余51 (34.0％)段位于其他节段.MB的平均长度和厚度分别为(17.6±5.7)mm,(2.7±0.7)mm.LAD中段的MCA从心脏收缩期到舒张期的管径变化为(1.2±0.5) mm,而且41％的MCA在心脏收缩期管径狭窄达到50％以上.结论 利用256层CT除了可以描述MB-MCA的形态学特点,还可以利用多时相重建技术在一定程度上评价MCA在心脏收缩期和舒张期的变化情况.
目的 利用256層螺鏇CT冠狀動脈成像探討心肌橋-壁冠狀動脈(MB-MCA)的形態學特徵及多時相重建量化分析MCA在心髒收縮期和舒張期的變化.方法 收集自2010年6月至2011年4月來北京中日友好醫院放射科進行冠狀動脈成像檢查的861例患者的影像資料.由兩位有經驗的放射科醫師獨立分析患者的影像資料,噹兩者意見取得一緻時,MB-MCA的診斷成立.描述MB-MCA分佈,併在心髒收縮期和舒張期分彆記錄位于LAD的MB-MCA的長度、厚度以及血管直徑,由此可以計算其在收縮期及舒張期的變化情況.結果 在861例患者中有131( 15.2％)例存在150段MB-MCA,其中99 (66.0％)段MB-MCA位于LAD中段,剩餘51 (34.0％)段位于其他節段.MB的平均長度和厚度分彆為(17.6±5.7)mm,(2.7±0.7)mm.LAD中段的MCA從心髒收縮期到舒張期的管徑變化為(1.2±0.5) mm,而且41％的MCA在心髒收縮期管徑狹窄達到50％以上.結論 利用256層CT除瞭可以描述MB-MCA的形態學特點,還可以利用多時相重建技術在一定程度上評價MCA在心髒收縮期和舒張期的變化情況.

Objective To determine the morphological characteristics of myocardial bridge and mural coronary artery ( MB-MCA ) and initially quantify the changes of MB-MCA in diastole and systole phase with multiple-phase reconstruction technique using 256-slice CT angiography (256-slice CTA).Methods We retrospectively collected the coronary artery imaging data of 861 patients undergoing 256-slice CTA with suspected or documented coronary artery disease.The images were reviewed by two independent radiologists,the diagnosis of MB-MCA was confirmed when consistency was obtained.The length,diameter and thickness of MB-MCA in the middle segment of LAD ( LAD2 ) in diastole and systole phase were recorded,and changes of MB-MCA were calculated.Results Among the 861 patients,150 MB-MCA were found in 131 patients (15.2％).99 MB-MCA (66.0％) were located in LAD2,the remaining 51 (34.0％ ) in the other segments of coronary arteries.The average length and thickness of MB was ( 17.6 ±5.7) mm and (2.6 ± 0.7 ) mm,respectively.The average diameter change of MCA in LAD2 from systole phase to diastole phase was ( 1.2 ±0.5) mm,and 41％ of MCA have diameter stenosis more than 50％ in systole phase.Conclusion The changes of MB-MCA from diastole to systole phase could be determined to some extent by 256-slice CTA multiple-phase reconstruction technique.
