DTPA Renal Scan

A DTPA renal scan provides functional information about your kidneys.

What will happen when you have your DTPA Renal Scan

The basic procedure for performing a DTPA Renal Scan may vary slightly depending on the specific information that we require about your kidneys prior to your scan. For example a blood pressure tablet or an injection called Lasix may need to be given either prior to or at some stage during the examination.

  • Prior to the scan a small intravenous injection of the ‘kidney tracer’ will be injected into a vein in your arm
  • The scan is started immediately

You must inform the Nuclear Medicine Physician or the Nuclear Medicine Technologist if you think you may be pregnant or are breast feeding.

What you need to do and how to prepare for the test

The scan is performed with the Gamma Camera underneath the scanning bed close to your body but you do not go through a ‘tunnel’.  You will not be required to undress for the scan.

  • You will need a referral from your doctor
  • DTPA Renal scans require an appointment
  • Please inform booking staff if you are, or think you could be, pregnant or are breastfeeding
  • Advise staff of any blood pressure medication you are taking
  • Please bring any previous relevant X-rays or scans to your appointment
  • You must drink 1 litre of water in the 2 hours prior to your examination
  • You can go to the toilet as often as you need to
  • You may be in the department for a period of between 30 and 90 minutes in total depending on your medical history and the type of scan required
  • You should not experience any side effects from the examination
