Parathyroid scan: Instruction for patients

This leaflet provides information to patients undergoing a Sestamibi Parathyroid scan.

What is a Sestamibi Parathyroid Scan?

A Sestamibi Parathyroid Scan is a diagnostic examination to determine the anatomy and function of your parathyroid glands. These are four small glands embedded in the back surface of the thyroid gland, situated in the neck.

How do I prepare for a Sestamibi Parathyroid Scan?

  • No special preparation necessary prior to the scan. You may eat and drink as usual
  • It is important that you inform us if you are breast feeding or are (or think you could be) pregnant. This study may not be suitable for pregnant women
  • If you are taking thyroid medication, please inform us before the scan.
  • You will not be asked to change your clothes but will be requested to remove any jewellery around the neck prior to the scan.

 

What happens during a Sestamibi Parathyroid Scan?

On the appointed date, initially a scan of your thyroid gland will be acquired 30 minutes after radio-isotope injection. After that, the scan of your parathyroid glands will be taken, 10 minutes and 2 hours after radio-isotope injection. You will be asked to remain still during scan acquisition. The duration of the first scan is 20 minutes. We may acquire a SPECT CT (Single Photon Emission Computed Tomography) 3-dimensional scan also, during which the camera will rotate over a 360 degree arc around you, allowing for reconstruction of an image in three dimensions. This second scan will take approximately 45 minutes after which you can go home.
