Thyroid Scan and Uptake

Your physician has requested that you have a thyroid scan. This is a simple, non-invasive way to evaluate the size, shape, and location of your thyroid gland. The test requires the injection in an arm vein of a very small amount of the radioactive element called Technetium. The radioactivity associated with this test is negligible. The only requirement for this study is the discontinuation of thyroid medication, such as Synthroid, 4 weeks prior to the examination and no IV contrast agents for 2 months. If there are any questions regarding discontinuation of thyroid medication, contact your physician.

Approximate exam time: 1 hour the first day, 30 minutes the second day.

To outline our requirements, you will:

  1. After registration check in with our receptionist at Medical Imaging
  2. You will then be escorted to Nuclear Medicine where a short history will be taken.
  3. You will be administered with the Technetium into an arm vein. You will experience no ill effects.
  4. You will need to wait approximately 10 minutes while the injected Technetium is localized in the thyroid gland.
  5. The technologist will instruct you drink a cup of water.
  6. The technologist will position you for 4 pictures. The entire study takes about 30-45 minutes.
  7. Review of the images by the nuclear medicine physician takes approximately 15 minutes.

If your physician has requested that you have a thyroid uptake, you will administered a capsule, which contains a small amount of radioactive iodine. The radioactivity associated with this test is negligible.

The requirements for this study are discontinuation of thyroid medication, such as synthroid, 4 weeks prior to the examination and no IV contrast agents for 2 months. If there are any questions regarding discontinuation of thyroid medication, contact your physician.

  1. You will be given the radioactive pill to swallow. You will experience no ill effects.
  2. You will be released from the Nuclear Medicine and be given a return time for the following day.
  3. The following day the technologist will place a gamma probe on your thyroid gland and measure the radioactivity for 3 minutes.
  4. The results will be verified by the Radiologist and you will then be released from Nuclear Medicine.

Note: Inpatients will be transported to Nuclear Medicine for this test.
