In the realm of advanced medical imaging, the DRCG (Dynamic Renal Cortical and Gated) scan, commonly referred to as the “gamma scan,” is an invaluable diagnostic source used to study the functionality and health of the kidneys. Employing radioactive tracers and specialized cameras, the DRCG scan provides detailed insights into kidney function, blood flow, and abnormalities, aiding in the diagnosis and management of various renal conditions.
