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.
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. This nuclear imaging technique reveals the presence and location of pathological parathyroid tissue. [7]
A nuclear medicine parathyroid scan demonstrates a parathyroid adenoma adjacent to the left inferior pole of the thyroid gland. The above study was performed with Technetium-Sestamibi (1st column) and iodine-123 (2nd column) simultaneous imaging and the subtraction technique (3rd column).
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]

Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), [2] but is able to provide true 3D information. This information is typically ...
Radioisotope renography is a form of medical imaging of the kidneys that uses radiolabelling.A renogram, which may also be known as a MAG3 scan, allows a nuclear medicine physician or a radiologist to visualize the kidneys and learn more about how they are functioning. [1]
