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.
Technetium (99m Tc) sestamibi (commonly sestamibi; USP: technetium Tc 99m sestamibi; trade name Cardiolite) is a pharmaceutical agent used in nuclear medicine imaging. The drug is a coordination complex consisting of the radioisotope technetium-99m bound to six (sesta=6) methoxyisobutylisonitrile ( MIBI ) ligands .
These employ the same radioligands and have the same uses as SPECT scanning, but are able to provide even finer 3-D localization of high-uptake tissues, in cases where finer resolution is needed. An example is the sestamibi parathyroid scan which is performed using the 99m Tc radioligand sestamibi, and can be done in either SPECT or SPECT/CT ...
The RAIU test is a reliable measurement when using a dedicated probe with a reproducibility of 1 percent and a 95%-least-significant-change of 3 percent. [3] The normal uptake is between 15 and 25 percent, but this may be forced down if, in the meantime, the patient has eaten foods high in iodine, such as dairy products and seafood. [4]
Nuclear medicine imaging methods are used by surgeons to locate which parathyroid gland is responsible for hyperparathyroidism or to find ectopic parathyroid adenomas, most commonly found in the anterior mediastinum. [citation needed] Historically, technetium sestamibi scintigraphy was the main method used or this indication. [39]
A parathyroid adenoma is a benign tumor of the parathyroid gland. It generally causes hyperparathyroidism; there are very few reports of parathyroid adenomas that were not associated with hyperparathyroidism. [1] A human being usually has four parathyroid glands located on the posterior surface of the thyroid in the neck.

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:
