Is a radionuclide scan that uses dimercaptosuccinic acid (DMSA) in assessing renal morphology, structure and function.
It involves using radioactive technetium-99m, combined with DMSA and injected into a patient, followed by camera imaging.
A DMSA scan is usually a static image.
The major clinical indications: are the detection or evaluation of a renal scar, the small or absent kidney, an occult duplex system, certain renal masses, systemic hypertension or suspected vasculitis, as a test for the diagnosis of acute pyelonephritis.
Sensitivity for acute pyelonephritis may be as low as 46%.
