[Magnetic resonance tomography of the heart in primary pulmonary hypertension].
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.
