Renal DMSA
What is a DMSA (dimercaptosuccinic acid) and DTPA renal scan?
A DMSA renal scan is used to assess the anatomy and physiology of each kidney. This scan is generally performed on children to determine if there is any renal scarring caused by Urinary Tract infections.
How is the test done and how long does it take?
Part 1- the first part of the test is where a cannula will be placed into a vein and a small amount of radiotracer is injected. It takes at least 3 hours for the injection to go to the kidneys, the technologist will give you a time to come back for the delayed images.
Part 2- After the 3 hours break the scanning will begin, this is where the kidneys are scanned for about 30- 40minutes.
Is it painful and are there any side effects?
No. There are no side effects or reaction from the injection. The injection does NOT contain iodine and is therefore safe in people who are allergic to radiological contrast injections.
Can I stay with my child during the scan?
YES - In Nuclear Medicine we encourage involvement from the parents and you will be able to stay with your child for the duration of their study. There is no radiation emitted from our cameras so it is very safe to sit with and touch your child throughout the study.
Can I take my normal medication?
Yes. Take all of your normal medications.
Can I eat and drink on the day of my test?
Yes. There is no need to fast prior to this test.
What if I am pregnant?
Please inform the Doctor or the Technologist if you are or there is a chance you are pregnant or are breastfeeding.
When do I get the results?
The Nuclear Medicine Physician will convey urgent results to your referring Doctor, otherwise your result will be available the following day between 10am to 4:30pm.
Can I drive home after the scan?
Yes.
