Radioisotope renography is a form of medical imaging of mag3 lasix renogram kidneys that uses radiolabelling. After injection into the venous system, the compound is excreted by the kidneys and its progress through the renal system can be tracked with a gamma camera.
A series of images are taken at regular intervals. If the kidney is not getting blood for example, it will not be viewed at all, even if it looks structurally normal in medical ultrasonography or magnetic resonance imaging. MAG3 is preferred over Tc-99m-DTPA in neonates, patients with impaired function, and patients with suspected obstruction, due to its more efficient extraction. The technique is very useful in evaluating the functioning of kidneys.
Radioisotopes can differentiate between passive dilatation and obstruction.
