CT examination with iohexol (or other iodine contrast media with the same pharmakokinetics as iohexol) as marker of GFR can be used to determine the relative GFR of the two kidneys. The advantages are ability to determine GFR of each kidney at all places were a CT machine is available and the ability to get both morphology (CT images) and function (GFR determination) on one occasion and following one contrast medium injection.
