Thyroid Evaluation

Thyroid function tests can help diagnose hyper thyroidism or hypothyroidism. Ultrasound can identify nodules and cysts, provide measurements of these lesions, and identify areas that are suspicious for cancer. A thyroid scan is a nuclear medicine test that can identify whether nodules are "hot" or "cold". Hot nodules can be associated with hyperthyroidism. Cold nodules are more likely to harbor malignancy. Fine needle aspiration (FNA) biopsy can help determine if a thyroid nodule is malignant. It is often done with ultrasound guidance.
