Overview
Other Imaging Findings
Thyroid Scan (radioiodine scintigraphy)
- Nuclear medicine can be used to image the thyroid with radioactive technetium (Tc) or iodine (I) imaging of the thyroid.[1]
Key Findings in Radioiodine Scintigraphy in Thyroid Adenoma
- Cold – 85% of nodules are cold. 5–8% of cold and warm nodules are malignant.[2]
- Functioning nodules – The cells in the nodule take up the iodine much like a normal cell does. The likelihood of cancer is very low in these types of nodules, and a biopsy is usually not necessary.
- Hot – 5% of nodules are hot. Malignancy is virtually nonexistent in hot nodules.[3]
- An 123I scan showing a hot nodule, accompanied by a lower than normal TSH, is strong evidence that the nodule is not cancerous.
