caption_attribution_description: English: Renal imaging in posteroanterior position (R = right kidney, L = left kidney). A. 99mTc-DTPA renal scintigraphy shows vascular bed over the left kidney without visualization of the parenchyma with practically afunctional renographic curve of the same kidney. B. 99mTc-MAG3 scintigraphy shows very pale left kidney becoming increasingly better visualized later. Renographic curve of the left lidney shows obstruction over the third phase of the renogram.
context_page_description: Radioisotope renography is a form of medical imaging of the kidneys that uses radiolabelling. A renogram, which may also be known as a MAG3 scan, allows a nuclear medicine physician or a radiologist to visualize the kidneys and learn more about how they are functioning. MAG3 is an acronym for mercapto acetyl tri glycine, a compound that is chelated with a radioactive element – technetium-99m.
  The two most common radiolabelled pharmaceutical agents used are Tc99m-MAG3 and Tc99m-DTPA. Some other radiolabelled pharmaceuticals are EC and 131-iodine labelled OIH.

  The two most common radiolabelled pharmaceutical agents used are Tc99m-MAG3 (MAG3 is also called mercaptoacetyltriglycine or mertiatide) and Tc99m-DTPA (diethylenetriaminepentacetate). Some other radiolabelled pharmaceuticals are EC (Ethylenedicysteine) and 131-iodine labelled OIH (ortho-iodohippurate).
