Abstract
The present invention relates to a method for ex vivo measuring glomerular filtration rate (GFR) of a subject to whom a contrast agent has been administered, and to whom computed tomography (CT) or magnetic resonance imaging (MRI) including an excretory phase, an unenhanced phase, an arterial phase, and a nephrographic or a venous portal phase has been performed, said method comprising the step of calculating the clearance of the contrast agent from CT or MRI data using manual, automated or semi-automated segmentation software, thereby obtaining a measured GFR.
