Electrocardiogram gated magnetic resonance imaging was performed in nine healthy volunteers, in four patients with pulmonary hypertension, and in 16 patients with hypertrophic cardiomyopathy. Fifty two short axis images in diastole were examined to assess the usefulness of magnetic resonance imaging for the measurement of the thickness of the free wall of the right ventricle and the degree of hypertrophy of the right ventricular free wall in hypertrophic cardiomyopathy and pulmonary hypertension. Magnetic resonance imaging gave a clear image of 68% of the length of the right ventricular free wall, showing both the endocardial and epicardial margins. The mean (1 SD) thickness of the right ventricular free wall measured at a total of 512 points was 0.44 (0.12) cm in patients with hypertrophic cardiomyopathy, 0.29 (0.08) cm in healthy individuals, and 0.73 (0.27) cm in patients with pulmonary hypertension.
对9名健康志愿者、4名肺动脉高压患者和16名肥厚型心肌病患者进行了心电图门控磁共振成像检查。检查了52张舒张期短轴图像，以评估磁共振成像在测量肥厚型心肌病和肺动脉高压患者右心室游离壁厚度及右心室游离壁肥厚程度方面的实用性。磁共振成像清晰显示了68%的右心室游离壁长度，同时显示了心内膜和心外膜边缘。在总共512个点测量的右心室游离壁平均（标准差）厚度，肥厚型心肌病患者为0.44（0.12）厘米，健康个体为0.29（0.08）厘米，肺动脉高压患者为0.73（0.27）厘米。
