Non-contrast-enhanced MRA of the renal arteries with Time-SLIP using a 3-T MRI system incorporating Multi-phase Transmission was compared with that using a 1.5-T MRI system. In the 3-T system, the BBTI value at which the renal arteries were visualized out to their peripheral branches matched the BBTI at which the signal of the renal parenchyma reached the null point. The 3-T system incorporating Multi-phase Transmission was found to have superior visualization capabilities as compared to the 1.5-T system and was therefore judged to be of greater clinical usefulness.
