Example of cine FISS ASL for dynamic flow visualization in the right renal artery and abdominal aorta of a healthy subject. Left: maximal intensity projection (MIP) from breath-hold radial QISS acquisition. Right: Oblique coronal cine FISS ASL (eight frames shown out of 32 acquired) using 6-mm slice thickness demonstrates progression of the labeled bolus along the entire main segment of the right renal artery (open arrows) into the small intrarenal branches, as well as progression of the labeled bolus in the aorta (solid arrows)
