Procedure Prep - Parathyroid Scan

How should I prepare for my exam?

If your previous imaging was not done at one of our locations, you may be asked to contact your former provider and request that your film be sent to us for a comparison study.

  • There are no restrictions prior to this exam. You may eat, drink and take all prescribed medications.
  • Wear comfortable clothes without metal fasteners, including zippers, buttons and snaps.
  • Arrive 15 minutes early to complete registration.
  • Bring your insurance card and a valid photo ID.
  • Please let us know if you have an insulin pump or glucose monitor. Our imaging machines may cause your device to malfunction, so it will need to be removed during your exam.


How long will my exam take?

A parathyroid exam can take up to 4 or 5 hours. This time allows for two sets of images to be taken, with a 2.5 to 3.5 hour wait between sets.


What happens during my exam?

During your exam, a small amount of radioactive tracer will be injected into a vein in your arm. The tracer allows your parathyroid glands to be seen by the nuclear medicine camera. After 10 minutes, you will be positioned on your back and images will be taken for approximately 20 minutes. A second set of images will be taken 2.5 to 3.5 hours later, and this imaging process will take another 30-45 minutes.


What happens after my exam?

Following the exam, your images will be interpreted by one of our board-certified radiologists. The findings will be sent to your healthcare provider.

Unless directed otherwise, you may drive, resume your normal diet, exercise and take all prescribed medications after your appointment.
