Description
Purpose: We assessed the wait time of non-contrast renal artery magnetic resonance (MR) angiography with a single breath hold using inflow inversion recovery-fan shaped inward outward view ordering technique in normal volunteers. Methods: The wait time (WT)-the duration between the data acquisition and the following inversion recovery pulse-was varied from 10 ms to 2000 ms, and the contrast ratio between the renal artery and the background structures for each WT was assessed quantitatively. A simulation was also performed. Results: The contrast ratio between the renal artery and each background structure with 2000 ms of WT was higher than that with 10 ms of WT. The contrast ratio between the renal artery and renal cortex with 1500 ms of WT was also higher than that with 10 ms of WT. In the simulation, when WT lengthened, the residual longitudinal magnetization of each background structure lowered. Conclusion: The WT affects contrast; adjustment of WT should be added to the assessment of the imaging parameter.
