Cine magnetic resonance imaging (MRI) was performed on 20 patients (mean age: 5.3 ± 4.4 years) with atrial, ventricular, or atrioventricular septal defects for evaluation of cardiac structure and blood flow. Prior to cine MRI, electrocardiographically gated MRI using multislice acquisition was performed on all patients to localize optimal slice location. Cine‐MRI was obtained with a 30° flip angle, 15 msec echo time, and 30 msec pulse repetition time, on a 256×256 or 128×128 acquisition matrix. Abnormalities of cardiac structure were well defined in all patients by gated cardiac imaging. In 18 of the 20 patients, cine‐MRI was able to detect shunt flow, visualized as a low intensity signal in comparison with the surrounding blood flow. Cine‐MRI can provide not only accurate anatomy of cardiac structures but functional assessment of the cardiac chamber, wall topology and flow relations. Cine‐MRI will become an important noninvasive technique for assessment of anatomy and physiology in congenital heart disease.
