Thirty-five patients with congenital obstruction of the right ventricular outflow tract underwent magnetic resonance (MR) imaging for evaluation of the pulmonary arteries. All patients underwent cardiac catheterization, and 33 underwent two-dimensional Doppler echocardiography. Results of the three imaging studies were compared. With regard to the presence of a pulmonary confluence, results of MR imaging and angiography were in agreement in 31 of the 35 patients (89%), results of echocardiography and MR imaging were in agreement in 27 of 33 patients (82%), and results of echocardiography and angiography were in agreement in 27 of 33 patients (82%). There was good correlation of measurements of main pulmonary artery size among all three methods and of right and left pulmonary artery size obtained at MR imaging and angiography. Echocardiographic measurements of right and left pulmonary artery size correlated poorly with those obtained at MR imaging and angiography. Results indicated that MR imaging is useful in evaluating the pulmonary arteries in patients with congenital heart disease.
35例先天性右心室流出道梗阻患者接受了磁共振（MR）成像检查，以评估肺动脉情况。所有患者均接受了心导管检查，33例患者接受了二维多普勒超声心动图检查。对这三项影像学检查结果进行了比较。关于肺汇合情况，35例患者中31例（89%）的MR成像结果与血管造影结果一致，33例患者中27例（82%）的超声心动图结果与MR成像结果一致，33例患者中27例（82%）的超声心动图结果与血管造影结果一致。三种方法对主肺动脉大小的测量以及MR成像和血管造影所测左右肺动脉大小之间均具有良好的相关性。超声心动图对左右肺动脉大小的测量结果与MR成像和血管造影所测结果相关性较差。结果表明，MR成像对于评估先天性心脏病患者的肺动脉情况很有用。
