Sestamibi parathyroid scan

Sestamibi Parathyroid Scan

A Sestamibi Parathyroid Scan (pronunciation: ses-ta-mi-bi par-a-thy-roid scan) is a diagnostic imaging procedure used to identify parathyroid adenomas or hyperplasia, which are common causes of primary hyperparathyroidism.

Etymology

The term "Sestamibi" is derived from the chemical compound technetium (99mTc) sestamibi, which is used as a radiotracer in this scan. The word "Parathyroid" refers to the parathyroid glands, four small glands located in the neck, near or attached to the back side of the thyroid gland.

Procedure

During a Sestamibi Parathyroid Scan, the patient is injected with a small amount of technetium (99mTc) sestamibi. This radiotracer travels through the bloodstream and is absorbed by the parathyroid glands. A special camera then takes images of the neck area, highlighting any glands that absorb too much of the substance. These overactive glands can then be identified and treated.
