A respiratory triggered variant of multiphase TrueFISP arterial spin labelling (ASL) is introduced to measure renal perfusion and transit time across the kidney at high spatial resolution. The increase in spatial resolution reduces partial volume effects allowing the visualisation of progressive inflow of labelled blood to the kidney and assessment of heterogeneity across the kidney, important in the study of renal physiology and disease. From the high resolution data the mean perfusion across the cortex was 329 85 ml/100g/min and the mean transit time was 472 178 ms.
