The aim of this study was to investigate the usefulness of static spin‐echo MR imaging at low field strength in evaluating postoperative pulmonary arterial supply Twenty‐seven patients operated on for complex congenital heart disease underwent cardiac MR imaging: 27 stenoses in 20 patients and 4 aneurysms were present in the material Five patients had normal pulmonary arteries Twenty stenoses were detected on MR images Five of the overlooked stenoses were located in the ventricular outflow tract or in the valvular region All four aneurysms were well depicted The final diagnoses were based on two‐dimensional echocardiography, Doppler and invasive studies MR correctly evaluated the pulmonary arterial supply in 21 patients In two cases the evaluation was incomplete and in the remaining four patients MR failed to show the senses MR imaging at 0.3 T is an effective non‐invasive tool for postoperative evaluation of pulmonary arteries.
