Abstract： 目的 探讨十字交叉心(CCH)在MR平扫及增强血管成像(MRA)的影像特点及其诊断价值.方法 对4例CCH的患者行MR检查,按照节段分析的方法和思路,多序列多角度多体位成像,充分显示CCH的解剖畸形.结果 所有心脏球室袢和内脏-心房位置关系均相适应.4例形态学右心室位于形态学左心室之上,水平室间隔,合并巨大室间隔缺损.2组房室瓣均呈前上-后下垂直排列,两心室流入道血流在空间位置上呈十字交叉.心室-大动脉连接关系异常,完全性大动脉错位1例;右室双出口3例.此外,3例合并肺动脉瓣及瓣下狭窄;1例合并肺动脉高压;1例并存房间隔缺损;1例右位主动脉弓及降主动脉.结论 MRI诊断CCH具有很高的准确性,有重要的临床应用价值.
