Thyroid Uptake and/or Scan

You have been scheduled for a thyroid uptake and/or scan, which involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects.

Preparation for the procedure:
You cannot have any food or drink four hours before the test. You need to be off all drugs containing iodine for one to six weeks prior to this test. Please do not stop any medication without consulting your physician. Radiographic iodinated contrast media also interferes with the uptake. Please inform the technologist if you have had any X-ray contrast in the last four weeks. If you have we may want to postpone your test for a few weeks. Please inform the technologist if you are pregnant or breast feeding. The imaging may be changed, or special instructions given based upon that information.

What to expect:
Once in the exam room you will be given a radioactive tracer in the form of a capsule to swallow. You may eat one hour after you swallow the capsule. You will be asked to return four to six hours later for the uptake and scan. Once in the scan room you will lie down on a table and special detector called a gamma camera will be placed near your neck. The uptake and scan takes approximately one hour.

The images will be reviewed and the results will be sent to your physician. Your physician will discuss these results with you and explain what they mean in relation to your health.
