A nuclear medicine renal scan is a specialized diagnostic test used to assess the functioning and blood flow of the kidneys. During this non-invasive procedure, a small amount of a radioactive material, usually technetium-99m, is injected into a vein. As the radioactive substance circulates in the bloodstream, a gamma camera captures images of the kidneys from various angles. These images provide valuable information about kidney function, including filtration rate and the flow of blood to the kidneys. By analyzing the data obtained from the nuclear medicine renal scan, healthcare providers can diagnose conditions like kidney disease, obstruction, or blood flow problems, helping to guide appropriate treatment decisions for the patient. It is a safe and essential tool in evaluating kidney health.
