Overview
Other diagnostic studies for thyroid adenoma include thyroid scan, which demonstrates hot, cold, or functioning nodule.
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 thyroid nodules are cold and 8% of cold and warm thyroid 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 thyroid nodules are hot. Malignancy is virtually nonexistent in hot nodules.[3]
- An 123I scan showing a hot nodule, accompanied by a lower than normal thyroid stimulating hormone, is strong evidence that the nodule is not cancerous.
