Five patients with angiographically proven diagnosis of double outlet right ventricle (DORV) were studied with magnetic resonance (MR) imaging. Magnetic resonance was compared with angiography and echocardiography. Contiguous electrocardiographic-gated spin-echo images were acquired on a 0.35 T imager. Magnetic resonance was equivalent to echocardiography in demonstrating relative relationships of the great arteries with respect to each other, the relative positions of the great arteries with respect to the ventricular septal defect (VSD), and the caliber of the great vessels. It was comparable in visualization of the size and position of the VSD and position of the atrioventricular valves. Due to limited spatial resolution, MR failed to identify chordal straddle of a tricuspid valve and incorrectly interpreted pulmonary stenosis as pulmonary atresia. A small patch leak of an internal baffle was only visualized on angiography. We conclude that MR is superior to echocardiography in the noninvasive assessment of the spatial arrangement and caliber of the great vessels. As such, it is a useful adjunct to echocardiography in the noninvasive assessment of DORV.

D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D004310	Double Outlet Right Ventricle	Incomplete transposition of the great vessels in which both the AORTA and the PULMONARY ARTERY arise from the RIGHT VENTRICLE. The only outlet of the LEFT VENTRICLE is a large ventricular septal defect (VENTRICULAR SEPTAL DEFECTS or VSD). The various subtypes are classified by the location of the septal defect, such as subaortic, subpulmonary, or noncommitted.
