Overview
Thyroid radioisotope scan may be helpful in the diagnosis of goiter.
Other Imaging Findings
- Thyroid radioisotope scan may be helpful in the diagnosis of goiter. Findings on a thyroid radioisotope scan are: [1] [2]
- Helpful in determining the functional activiity by distinguishing a nodule as hot, warm, or cold, based on the relative amount of uptake of radioactive isotope
- Hot nodules take up excessive amounts of isotope and indicate autonomously functioning nodules
- Cold nodules does not radioactive isotope and therefore indicate hypofunctional or nonfunctional thyroid tissue
- Warm nodules appear gray and suggest normal thyroid function
- The radioactive isotopes that are most commonly include Iodine-123, Technetium-99m and Iodine-131
- Helpful in determining the functional activiity by distinguishing a nodule as hot, warm, or cold, based on the relative amount of uptake of radioactive isotope
