An ASL-FAIR approach was used to measure kidney perfusion in the cortex of 14 native kidneys and 10 transplanted kidneys in subjects with a range of kidney function. Exams were repeated within each visit and on two separate days and evaluated for reproducibility. The average within day variations was 6 % and the average between day variations was 10 % for the native kidneys and 18 % for the transplanted kidneys.
