Mean times to peak-intensity in the eight regions of interest (ROI) selected in different kidney regions following the arterial blood vessel hierarchy. (a) Position of the ROIs marked in a corrosion cast of the kidney vessels (with permission from the Ruprecht-Karls-University Heidelberg, Institute of Anatomy and Cell Biology, S. Doll). (b) Position of the ROIs over an US image in the early phase after injection of US contrast medium. (c) Time-intensity curves in the different ROIs over 60 minutes after application of a bolus of US contrast medium into the suprarenal aorta and without application of iodinated CM.
