摘要
目的 :了解BalancedFFE电影磁共振成像进行右心室功能分析的价值和限度。方法 :分别用BalancedFFE电影磁共振和二维超声、实时三维超声心动图对 2 5例健康志愿者进行右心室舒张末期容积、收缩末期容积 ,每搏输出量以及射血分数等功能指标的测定 ,并比较其测量值。结果 :BalancedFFE电影磁共振测量 2 5例健康志愿者右心室舒张末期容积为 (10 1.3 2± 6.77)ml ,收缩末期容积为 (5 4.3 7± 6.41)ml ,每搏输出量 (5 2 .47± 2 .98)ml ,射血分数为 (65 .44± 5 .17) % ,与实时三维超声心动图测量值相关性良好 (r值在 0 .74～ 0 .98)。结论 :BalancedFFE电影磁共振能够准确测量右心室容积变化情况 ,对右心室功能评价具有很高价值。
Objective:To investigate the value and limitation of the balanced FFE cine MR imaging in analyzing right ventricular function.Methods:25 healthy volunteers were examed by balanced FFE cine MR imaging,2D echocardiography and real-time 3D echocardiography.The function features measured by different ways were compared with each other.Results:EDV,ESV,SV and EF of the right ventricle measured by balanced FFE cine MR imaging were (101.32±6.77)ml,(54.37±6.41)ml,(52.47±2.98)ml,(65.44±5.17)%.And the results proved to have good relativity with those from 2DE and RT3DE (r=0.74～0.98).Conclusion:Balanced FFE cine MR imaging has shown great value in measuring right ventricular function.
