A thyroid nuclear medicine scan provides your doctor with information that measure function to detect an overactive or underactive thyroid.
Exam preparation
- A CDI representative will call you prior to your appointment to provide specific instructions, and review health and insurance information.
- Please bring previous imaging study results (x-ray, MRI, CT, etc.) such as reports, films or CD-roms if available.
- Notify a member of CDI’s staff if you are nursing or if there is a chance you could be pregnant.
- Please arrive 15 minutes early to verify your registration and health information.
During the exam – what to expect
- You will lie down on a scanning table and receive an I.V. in your arm or hand.
- A radioactive contrast (dye) agent is injected into your vein that will give off energy “rays.”
- The substance will travel through the body and collect in the thyroid.
- A gamma camera will move over you and collect images and measurement based on the energy (gamma rays) being emitted from the thyroid.
- While the images are being obtained, you must remain as still as possible. This is especially true when a series of images is obtained to show how an organ functions over time.
After the exam – what to expect
- A radiologist who specializes in a specific area of the body reviews your images (i.e., a body radiologist will review the images of your thyroid).
- The radiologist prepares a diagnostic report to share with your doctor.
- Your doctor will consider this information in context of your overall care, and talk with you about the results.
- Most of the radioactivity passes out of your body in urine or stool. The rest simply disappears through natural loss of radioactivity over time.
