DMSA scan

Radioactive technetium-99m is combined with DMSA and injected into a patient, followed by imaging with a gamma camera after 2-3 hours.

[2] The major clinical indications for this investigation are Procedure: Patient is injected with 2-5 mCi of Technetium-99m DMSA intravenously and static imaging is done using Gamma camera after 2-3 hours.

Imaging time is approximately 5 - 10 minutes depending on the views taken.

Patient is asked to maintain good hydration before and after the radiotracer injection by drinking water or intravenous fluid administration, if patient cannot drink water for any reason.

The technetium-99m DMSA binds to the proximal convoluted tubules in kidney so the excretion pattern of the kidneys cannot be assessed by this for which renal dynamic scans using radiotracers like DTPA, MAG3 are used.
