Thyroid Sonogram

The purpose of this test is to produce pictures of the thyroid gland, and determine the difference between a sac containing fluid (cyst) and abnormal tissue that may or may not be malignant. The thyroid gland regulates metabolism.  It is located in front of the neck just below the Adam's apple and is shaped like a butterfly, with two lobes on either side of the neck connected by a narrow band of tissue.
