MRI has been utilized since its inception to study the anatomy and physiology of the heart. However, the sensitivity of MRI to motion has always posed a major challenge in imaging this organ. The purpose of this study was to develop a 3D MP-RAGE technique for the heart, and to apply it clinically. In the experimental study, data acquisition timing was discussed by normal volunteers. Changes in magnetization recovery time affected imaging contrast very little in the phantom study. Fourteen adults and 21 children were examined. In the adults, MP-RAGE images were rated as high in quality in the visual estimation. In the quantitative estimation, the images provided almost the same anatomical information as those of cine MRI. In the children, MP-RAGE was useful for cases of partial anomalous pulmonary venous drainage, particularly in the evaluation of abnormal pulmonary veins. The 3D MP-RAGE technique was useful in imaging the heart because it was possible to obtain continuous views in the same cardiac cycle and to reconstruct views from any direction after the examination.
