MR-tomography (MRT) was performed in 10 patients with primary pulmonary hypertension (PPH) and in 20 healthy volunteers. The investigation was performed by means of a MR-tomograph with a resistive magnet. ECG-triggering and multislice-multiecho method were used. MRT gave high quality images of the right heart in various phases of the cardiac cycle. The most characteristic symptoms of PPH exhibited by MRT were: forward rotation of the right ventricle (RV), pronounced dilation of the right heart, right ventricular myocardial hypertrophy, relative and absolute diminishing of the left ventricle size, paradoxical motion of the interventricular septum and alterations in its shape. 50% of the examined patients had highly intensive blood flow signal in the pulmonary artery lumen.
对10例原发性肺动脉高压（PPH）患者和20名健康志愿者进行了磁共振断层扫描（MRT）。检查采用带有电阻磁体的磁共振断层扫描仪进行。使用了心电图触发和多层多回波方法。MRT提供了心动周期各阶段右心的高质量图像。MRT显示的PPH最典型症状为：右心室（RV）向前旋转、右心明显扩张、右心室心肌肥厚、左心室大小相对和绝对减小、室间隔矛盾运动及其形态改变。50%的受检患者肺动脉腔内有高强度血流信号。
