This study is targeted to compare the performance of three-dimensional (3D) breath-hold gradient and spin-echo sequence (GRASE) and conventional respiratory-trigger fast spin-echo sequence (FSE) for magnetic resonance urography (MRU). Image quality and diagnostic performance of urinary tract dilation from two data sets were evaluated by three radiologists. The results showed that 3D GRASE MRU had a better performance compared with the FSE MRU, indicating 3D GRASE technique could be a feasible option for 3D MRU.
