We used a novel Golden-angle Radial Sparse Parallel
(GRASP) sequence to perform free-breathing
contrast-enhanced MR-urography with retrospective
reconstruction of dynamic large-FOV images of the
kidneys, ureters, and bladder at high spatial and high
temporal (between 1-4 seconds) resolution. This
technique provided visualization of the entire
urothelial system, including of the bladder mucosa
before gadolinium excretion, with reduced motion and
ghosting artifact compared with a standard DCE sequence.
