Multiphase True-FISP ASL is implemented in the kidney. This technique provides a robust method to map the transit time, perfusion rate and longitudinal relaxation time of the kidney in a total acquisition time of less than 5 minutes. Maps of these parameters are shown, with transit time maps depicting a clear increase in transit time from feeder vessels to the outer edge of the renal cortex, and perfusion maps displaying significant differences between renal cortex, medulla, and feeder vessels. The mean transit time to the renal cortex was 36852 ms, mean perfusion rate 24621 ml/100g/min and mean T1 113263 ms.
