MR Renography was widely used to provide renal functional information in recent studies. However, conventional 3-D whole kidney scan takes more than ten minutes to obtain MRR curves in diffuse renal disease. The purpose in this study was to investigate a higher temporal resolution scan protocol to reflect renal functional information. The center thin slab scan employed, instead of the whole kidney scan protocol, was proved feasible for reflecting whole kidney perfusion information, and it also significantly improved the temporal resolution of MRR.
