[Magnetic resonance tomography of the heart and major vessels in patients with pulmonary hypertension].
Potentialities of magnetic resonance imaging (MRI) have been studied for evaluation of patients with pulmonary hypertension. For this purpose 54 patients with primary and secondary pulmonary hypertension have been studied using resistive and superconductive MRI systems. MRI proved useful for determination of the cause of pulmonary hypertension (primary, secondary), assessment of the right heart chambers. The cine-MRI enabled detection of tricuspid and pulmonary regurgitation, paradoxical movement of the interventricular septum, thrombi in the pulmonary artery. There were some correlations between MRI parameters and indexes of pulmonary hemodynamics. As a non-invasive imaging modality MRI has a great diagnostic value in characterization of the heart and great vessels in patients with pulmonary hypertension.
