Technetium Tc 99m Sestamibi is indicated for: 1) detecting coronary artery disease by localizing myocardial ischemia (reversible defects) and infarction (non-reversible defects); and 2) evaluating myocardial function and developing information for use in patient management decisions.
What does a sestamibi scan show?
A sestamibi scan is used to evaluate the function of the parathyroid glands; these four glands are located in the neck and help manage the body’s calcium levels. To better understand the impact of a sestamibi scan, let’s examine this parathyroid gland assessment in detail.

Is sestamibi scan accurate?
Only the overactive parathyroid gland shows up…a very accurate test. The Sestamibi scan will display the hyperactive gland which is causing hyperparathyroidism in about 90 percent (90% sensitivity) of all patients. If the Sestamibi does show the hyperactive gland it is almost always correct (98-100% specificity).
How long does it take for results from a sestamibi scan?
