MR imaging of normal heart was done in 7 Volunteers who had no clinical evidence of cardiovascular disease, using KAIS 0.15 Tesla resistive magnet imaging system. Saturation recovery with spin echo tech-nique was imaging method. Echo delay (TE) was 32 msec. and repetition time was the same with pulse (R-R) interval since ECG gating was applied. Each imaging scan consisted of 6 slices, of which thickness was 15mm and imaging time was 15 minutes. Findings of MR imaging of normal hearts were analysed and the results were as follows: 1. Several normal anatomical structures including both atrioventricular chambers, septums and great vessels were well identified using contrast media. 2. in addition to the transaxial, sagittal and coronal sections. oblique 45$^{circ}$/45$^{circ}$revealed those normal anatomical structures of normal heat. ECG gated MR imaging is expected to be a very useful modality in the diagnosis of congenital and acquired heart disease in the future.
