A thyroid scan is used to deactivate thyroid tissue in patients who have thyroid cancer and have had partial thyroidectomies. This type of scan is also used to treat residual functioning thyroid cancer.
How do I prepare for the exam?
Before your exam, a radiologist and oncologist will consult with you and determine the amount of radioactive iodine (I-131) that will be given.
What can I expect during the exam?
A specially registered technologist in molecular imaging and an RN will conduct the thyroid scan.
Patients who receive larger doses will be hospitalized in a special lead-lined room. During the therapy, a patient can emit radiation, and exposure to the patient should be minimal. Children under 18 and pregnant women should not have contact with the patient until the radiation levels are safe. The radiologist or technologist will be able to provide you with detailed information regarding safe radiation levels.
What can I expect after the exam?
Unless your physician tells you otherwise, you may resume your normal activities after your molecular imaging scan. If any special instructions are necessary, you will be informed by a technologist, nurse or physician before you leave the molecular imaging department.
Your scan will be read by a radiologist specially trained in molecular imaging. A written report will be sent to your physician, who will contact you with results.
