Preparation for a Kidney Scan in Nuclear Medicine

A kidney nuclear medicine scan is a test to check how your kidneys look and how well they are working. Doctors also call it a renal scan, renal imaging, or renal scintigraphy. Your doctor may recommend that you get this scan because it offers information that other tests -- such as ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) -- can’t provide. The test uses a small amount of radioactive material that’s inserted into your body. A special camera and computer detect traces of that material in your kidneys in order to make images. The amount of radioactive material used is small, so the risk is low. You have to stay still during the test, and that’s uncomfortable for some people. If you have any of these conditions or issues, you should let your doctor know in advance: Your doctor will let you know whether you need to drink extra fluids before your scan or whether your bladder should be empty. 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 (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). 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. Processing then involves drawing a region of interest (ROI) around both kidneys, and a computer program produces a graph of radioactivity inside the kidney with time, representing the quantity of tracer, from the number of counts measured inside in each image (representing a different time point). 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.
