High Resolution Parathyroid Ultrasound
Ultrasound is an inexpensive and non-invasive method to examine and measure the shape and size of the parathyroid adenomas. Normal parathyroid glands are often difficult to see on ultrasound, but abnormal parathyroid glands may be enlarged and can be easily examined through ultrasound. During a parathyroid ultrasound, a handheld instrument called a transducer is passed back and forth over the neck to form a picture of the thyroid and parathyroid glands.
When correctly performed, High Resolution Parathyroid Ultrasound can identify over 50% of parathyroid tumors. Parathyroid ultrasound is a relatively inexpensive and non-invasive test that does not require radiation. Ultrasound of the thyroid and parathyroid glands is used pre-operatively to rule out thyroid nodules that may need to be evaluated prior to parathyroid surgery.
Typically, an ultrasound of the thyroid and parathyroid are performed together with a parathyroid scan. The ultrasound provides us with anatomic size and location of the adenoma, while the Sestamibi nuclear scan measures the “activity” of the adenoma.
