Answer

Radionuclide imaging with technetium-99m-mercaptoacetyltriglycine (99m Tc-MAG3),99m Tc-diethylenetriamine penta-acetic acid (99m Tc-DTPA), or iodine-131 (131 I)-hippurate can be used to assess renal blood flow, as well as tubular function. There is, however, a marked delay in the tubular excretion of radionuclide in prerenal and intrarenal AKI, limiting the value of nuclear scans.
