To look for scarring in the kidneys, a type of radionuclide scanning called dimercaptosuccinic acid (DMSA) scanning is used. In this procedure, which takes place in hospital, a small amount of radioactive DMSA is injected into a vein in the arm. After 2 hours, the DMSA collects in the kidneys and images of the organs are taken with a gamma camera. The scan takes about 30 minutes and is painless.
