A renal radionuclide scan can be used to screen for renal artery stenosis when performed with captopril administration; it also quantitates differential renal contribution to total glomerular filtration rate (GFR). However, radionuclide scans are unreliable in patients with a GFR of less than 30 mL/min/1.73 m².
