Nuclear medicine can be used to image the thyroid with radioactive technetium or iodine imaging of the thyroid. 
Cold 85% of thyroid nodules are cold and 8% of cold and warm thyroid nodules are malignant.  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.  An 123 I scan showing a hot nodule, accompanied by a lower than normal thyroid stimulating hormone, is strong evidence that the nodule is not cancerous.
