| 摘 要： | 目的 通过3.0T相位对比磁共振(PC-MRI)定量测量法洛四联症(TOF)术后远期患者的肺动脉反流程度,并与超声心动图结果进行分析,评价肺动脉反流与右心室容量及收缩功能的关系.方法 对42例TOF根治术后患者于1个月内先后接受超声心动图及心脏MR检查.以PC-MRI测量肺动脉反流分数(PRF),分为轻度、中度、重度；对PC-MRI所见与超声心动图测量的PRF程度进行相关分析.比较不同PRF程度间右心室舒张末容积指数(RV-EDVI)、右心室收缩末容积指数(RV-ESVI)、右心室射血分数(RVEF)的差异.结果 PC-MRI与超声心动图显示的肺动脉反流严重程度呈正相关(rs=0.606,P＜0.001).轻度、中度及重度PRF组RV-EDVI中位数分别为89.45、108.05及133.50 ml/m2(x2=12.530,P=0.002),RV-ESVI中位数分别为50.40、64.85及81.30 ml/m2(x2=13.173,P＜0.01),但三组间RVEF差异均无统计学意义(x2=0.032,P＞0.05).结论 3.0T PC-MRI测量肺动脉反流严重程度与超声心动图有良好相关性.RV-EDVI及RV-ESVI与肺动脉反流程度密切相关；随反流严重程度加重,RV-EDVI及RV-ESVI增大,而RVEF保持稳定.
