About Renal Scan (DTPA)Renal Scan (DTPA)
A Renal Scan (DTPA) is a nuclear medicine test that assesses kidney function and blood flow. It involves injecting a radiotracer called DTPA (diethylenetriamine pentaacetate) into the bloodstream, which is then filtered by the kidneys. A gamma camera captures images of the radiotracer's distribution and excretion over time, providing detailed information about renal perfusion, function, and urinary tract obstruction. This scan is commonly used to evaluate conditions such as renal artery stenosis, kidney obstruction, and differential kidney function.
