MR imaging of congenital heart disease.
MR examination of patients with congenital heart disease is a useful means of explicitly demonstrating chamber morphology and, in particular, morphologic changes caused by physiologic changes brought on by particular defects. Use of MR techniques allows characterization of chamber morphology for determination of cardiac connections and great artery relationships. The high-contrast resolution of spin echo acquisition provides important morphologic detail. Cine gradient echo techniques complement spin echo acquisition by providing functional and flow information. Although MR examination complements echocardiographic investigation in pediatric and adult patients, is may be useful for replacing angiocardiography, shortening examination time, and decreasing morbidity in diagnostic workups of these patients.
