Cardiac output and pulmonary vascular resistance (PVR) were measured in 19 patients by means of catheterization of the right side of the heart. Results were compared with the cardiac output and indexes of pulmonary arterial blood flow estimated with velocity-encoded magnetic resonance (MR) imaging. Correlations were good between estimates with right-sided heart catheterization and those with velocity-encoded MR imaging. By providing accurate pulmonary arterial blood flow measurements, velocity-encoded MR imaging allowed distinction of patients with high PVR from subjects with normal PVR.
通过右心导管插入术对19名患者的心输出量和肺血管阻力（PVR）进行了测量。将结果与通过速度编码磁共振（MR）成像估算的心输出量和肺动脉血流指数进行了比较。右心导管插入术的估算值与速度编码MR成像的估算值之间具有良好的相关性。通过提供准确的肺动脉血流测量，速度编码MR成像能够区分高PVR患者与正常PVR受试者。
