There have been several reports about non-contrast-enhanced MRA of renal artery or hepatic vessels, but not for uterine artery. As for uterine artery, we should consider the distance from aortic artery and there are two vessels that reach the uterus bilaterally. We aimed to evaluate the reasonable BBTI for obtaining non-contrast-enhanced MRA of uterine artery using time-SLIP technique at 3.0-T. By evaluation of qualitative and quantitative analysis of arterial and background signals, the optimal BBTI for visualizing uterine artery by time-SLIP technique were between 1400-1600msec..
