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.
This nuclear imaging technique reveals the presence and location of pathological parathyroid tissue. [7] In cases where 99m Tc-sestamibi scintigraphy or SPECT delivers inconclusive results, other imaging modalities and tracers can be applied. For detection of multiple parathyroid adenomas, positron emission tomography (PET) using the ...
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]

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 ...
Scintigraphic or single-photon emission computed tomography (SPECT) imaging with the radiotracer 99m Tc-sestamibi of head, neck and upper thorax is the first-line nuclear imaging modality for localizing parathyroid adenomas, having a sensitivity and specificity of 70–80%. Sensitivity falls down to 30% in case of double/multiple parathyroid ...
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
