ULTRASONOGRAPHY OF THE THYROID AND PARATHYROID-GLANDS

High-frequency ultrasonography is ideally suited to imaging of the thy roid and parathyroid glands by virtue of their superficial location in the neck. Ultrasonography of the thyroid is most commonly used in the evaluation of the solitary nodule. Ultrasonography of the parathyroid glands is usually performed to evaluate and localise parathyroid abno rmalities in patients with hypercalcemia. The increased diagnostic acu men offered by this modality allows a realistic working diagnosis and leads to a rational management strategy.
