Motivation: Conventional RT-FSE MRU often requires extended acquisition times, challenging for patients with limited breath-hold capability.
Goal(s): To evaluate the feasibility and performance of short-duration BH-GRASE MRU in reducing scan time while maintaining diagnostic quality.
Approach: Forty-four patients were scanned using both RT-FSE MRU and BH-GRASE MRU with varying parameters. Image quality, SNR, and CNR were assessed.
Results: BH-GRASE MRU reduced scan time to 19 seconds with sufficient image quality, showing strong consistency with RT-FSE MRU in evaluating urinary tract obstruction.
Impact: BH-GRASE MRU reduces scan time to 19 seconds without impacting diagnostic accuracy, benefiting patients unable to sustain long breath-holds. This improvement broadens MRU accessibility.
