A DMSA scan is a radionuclide scan that uses dimercaptosuccinic acid (as a radioactive tracer) in assessing the renal morphology, structure (static scan) not a functional scan. It is now the most reliable test for the diagnosis of acute pyelonephritis.[1] The major clinical indications for this investigation are the detection and/or evaluation of a renal scar, the small or absent kidney (renal agenesis), an occult duplex system, certain renal masses, systemic hypertension or suspected vasculitis.[2]
