To study whether shortening of acquisition time for selective hepatic artery visualization is feasible without image quality deterioration by adopting two-dimensional (2D) parallel imaging (PI) and short tau inversion recovery (STIR) methods. Shortening of the acquisition time for selective hepatic artery visualization was feasible without deterioration of the image quality by combination of 2D-PI and STIR methods. It will facilitate using non-contrast-enhanced MRA in clinical practice.
