DMSA SCAN

What Is a DMSA SCAN?

A DMSA SCAN is a nuclear medicine investigation done for evaluation of kidney’s. In this investigation, a small amount of radiotracer (radiation labelled molecule) is injected into the patient. Then after a predetermined waiting period (usually a few hours) a scan of the distribution of the radiotracer is done using a gamma camera.

Please inform booking staff if you are, or think you could be, pregnant or are breastfeeding

What Are the Uses of Dmsa Scanning?

The most common use of DMSA scanning is for the purpose of finding out the presence of scars in the kidney. Other conditions where it might help include:

  • Pyelonephritis
  • Renal function in the left and right kidneys
  • Renal ectopia
  • Renal Infarction
  • Hypertension
  • Horseshoe kidney
  • Acute renal failure
  • Multicystic dysplastic kidneys
  • Trauma
What Are the Preparations for a Dmsa Scan?

There is no special preparation needed for this test. Your child can eat or drink as usual.

  • It is helpful to give your child a simple explanation as to why a DMSA renal scan is needed and assure him/her that you will be with him/her for the entire time.
  • You may want to bring your child’s favourite book, toy, or comforting object to use during waiting times.
Is a Dmsa Renal Scan Safe?

We are committed to ensuring that your child receives the smallest radiation dose needed to obtain the desired result.

  • Nuclear medicine has been used on babies and children for more than 40 years with no known adverse effects from the low doses employed.
  • The radiopharmaceutical contains a very tiny amount of radioactive molecules, but we believe that the benefit to your child’s health outweighs potential radiation risk.
  • The camera used to obtain the images does not produce any radiation.
  • It is safe to be in the room with your child if you are pregnant or nursing.
