Renal function can be analyzed by time-resolved BOLD MRI before, during and after a functional challenge. Inconsistent kidney positions from one measurement to another hamper the analysis of renal parenchyma and medulla over time. Here, a new method, Kidney ALIgnment for BOLD Renal Imaging (KALIBRI), with prospective rigid image registration of each kidney is proposed.
