PRP's Thyroid Scan Service Information

Thyroid radioisotope scan.

A Thyroid scan is used to evaluate your thyroid function, shape, location and size.

Please advise us beforehand

Please make staff aware if

  • you are or think you could be pregnant.
  • you are breastfeeding, claustrophobic and/or if you are the primary/sole carer for small children when you book your appointment.
  • you have had any reactions to injections used for imaging.
  • you think you may have had a recent CT scan with intravenous contrast

Please bring any previous nuclear medicine scans or any other scans relating to the current problem.


You may be asked to cease certain medications or vitamin supplements prior to the test.

Bring any previous Nuclear Medicine scans or any other scans relating to the area of interest, as well as any recent blood tests measuring thyroid function to your appointment.

Eat and drink as normal before and after your thyroid scan.

How long does it take?

In total, your scan should take approximately 1 hour.


Part 1: You will be given a small injection of a radioactive tracer that is taken up by your thyroid gland. This injection shouldn’t make you feel any different.

Part 2: Images of your neck and thyroid are taken after a wait of 20min and will take 15-40 minutes.

After your examination

Eat and drink as normal before and after your thyroid scan.

Resume normal activities (including driving) following your scan.

It is recommended that you minimise close contact with others (especially babies and small children) for up to 4 hours.

Your images and report

All images for your study will be available on the myPRP patient portal soon after your examination is complete. A report that includes a link to your study will be sent directly to your referring doctor. PRP Imaging will store digital copies of all studies on our secure database for comparison with any future examinations.

Normal and abnormal studies are both important for your management and PRP Imaging encourages you to return to your doctor for review of the results.
