[Usefulness of the sagittal section imaging technique in whole-heart coronary MRA(WHCA)].

Whole-heart coronary MRA(WHCA)was performed in transaxial and sagittal sections in random order in 10 healthy volunteers to obtain coronal section multiplanar reconstruction(MPR)at an interval of 0.5 mm and thickness of 1 mm for evaluation. Visual evaluation showed sagittal section imaging to be superior to transaxial section imaging in 12 out of a total of 20 regions in the left and right proximal coronary arteries.
