A sestamibi parathyroid scan is a procedure in nuclear medicine which is performed to localize parathyroid adenoma, which causes Hyperparathyroidism. [1] Adequate localization of parathyroid adenoma allows the surgeon to use a minimally invasive surgical approach.
The parathyroid gland takes up 99m Tc MIBI following an intravenous injection, and the patient's neck is imaged with a gamma camera to show the location of all glands. A second image is obtained after a washout time (approximately 2 hours), and mitochondria in the oxyphil cells of the abnormal glands retaining the 99m Tc are seen with the gamma ...
Micrograph of a parathyroid adenoma (left) and normal parathyroid gland (right). H&E stain.. Hyperparathyroidism is confirmed by blood tests such as calcium and PTH levels. A specific test for parathyroid adenoma is sestamibi parathyroid scintigraphy, often referred to as sestamibi scan or, more colloquially, MIBI scan.
A sestamibi scan is a medical imaging technique using gamma rays from the radioactive decay of the manmade compound Technetium (99mTc) sestamibi to penetrate muscle and other tissue to view their condition and function. It may refer specifically to: MIBI scan, a type of cardiac imaging to assess the condition and function of the heart
Such scans are most useful for tissues outside the brain, where location of tissues may be far more variable. For example, SPECT/CT may be used in sestamibi parathyroid scan applications, where the technique is useful in locating ectopic parathyroid adenomas which may not be in their usual locations in the thyroid gland.

Parathyroidectomy is the surgical removal of one or more of the (usually) four parathyroid glands.This procedure is used to remove an adenoma or hyperplasia of these glands when they are producing excessive parathyroid hormone (PTH): hyperparathyroidism.
After a CT scan and MRI, doctors found multiple tumors on my brain, which they believe have been growing for at least 6 months.” “Two of the tumors will be surgically removed today.
