The purpose of this study was to examine mainly LAD about the possibility of the practical use of REPI 4D MRA. REPI 4D MRA with choice of the VENC=30 cm/s could well visualize the coronary arteries from proximal to distal of the LAD.

REPI can be visualized in a well-balanced
manner from the ostial to distal portion of the left
anterior descending artery.
