[Magnetic resonance tomography in pediatric cardiology]

Magnetic resonance imaging (MR) is a relatively new non-invasive imaging method that has not been used as a routine procedure in pediatric cardiology. To evaluate MR in pediatric cardiology we performed 110 examinations in 91 children during the period from December, 1984, to November, 1987. The children were divided into the following groups: 1) Diseases of the great vessels (54 examinations in 39 children); 2) Cardiac diseases (42 examinations in 39 children); 3) Diseases of the pericardium (four examinations in three children); 4) Ten children without cardiovascular diseases (imaging of the heart in conjunction with examination of other organs). The ages of the children ranged from five weeks to 19 years in the following distribution: 13% infants, 20% children 2-5 years, 30% children 6-14 years, 37% adolescents from 15 to 19 years. On the basis of our experiences we conclude that MR can be used as an additional diagnostic tool in pediatric cardiology, especially for imaging of areas that are not well visualized by echocardiography, i.e., the great vessels and their branches and in addition, the right ventricle, in older children.
