Thyroid scan...: Did you have thyroid function tests (blood tests)? There are various reasons to order a thyroid scan. Thyroid scans can be helpful in diagnosing thyroiditis, graves disease, hyper functioning nodules, or thyroid cancer. Ultrasound shows the anatomy but thyroid scan shows the function. If they saw nodules on ultrasound, the thyroid scan will determine if the nodules are hyper/hypo functioning.

Not really: Sometime ultrasound exam of thyroid gland demonstrates nodules, solid or liquid.Nuclear medicine scan used to determine activity or functioning of nodule, decrease (hypo) or increased (hyper). Thyroid cancer accounts for a small percentage of thyroid nodules.Hot nodules are almost always noncancerous, but a few cold nodules are cancerous. Nodules larger than one cm usually are referred for biopsy.
