Blood oxygenation level dependent MRI (BOLD MRI) is a mapping of R2* which is inversely correlated to the concentration of blood haemoglobin. This abstract presents two items: a new method for the post-processing of renal BOLD MRI and an analysis of a clinical study on the response of the R2* map to the diuretic furosemide using our new post-processing method. This method is based on the radial R2* distribution, which accounts for kidneys anatomy and gives information on the spatial distribution of the R2* map in the cortex and medulla without using arbitrarily defined and operator-dependent regions of interest.
