Health Information
Thyroid Scan
What To Think About
- Blood tests may be done before a thyroid scan to measure the amount of thyroid hormones (TSH, T3, and T4) in your blood. For more information, see the topics Reference Thyroid-Stimulating Hormone (TSH) and Reference Thyroid Hormone Tests.
- Cancer of the thyroid is usually treated with surgery. If the tumor is large, has spread outside the thyroid gland, or has recurred, it may then be treated with very high doses of radioactive iodine. After treating recurring thyroid cancer, a scan of the entire body can be done to see where the cancer has spread.
