What is a nuclear medicine sestamibi scan?
The Nuclear Medicine Parathyroid Scan is an exam to determine the function and health of the parathyroid gland which regulates calcium uptake in the body. Nuclear Medicine scans are performed using very small amounts of radioactive material.
Can you eat before a sestamibi scan?
Individuals can eat and drink as they normally would leading up to a sestamibi scan. Additionally, patients won’t have to remove any clothing or jewelry as part of a sestamibi scan.
What does sestamibi stand for?
Technetium Tc-99m sestamibi (commonly sestamibi) is a pharmaceutical agent used in nuclear medicine imaging. The drug is a coordination complex consisting of the radioisotope technetium-99m bound to six methoxyisobutylisonitrile (MIBI) ligands, hence the name sesta (6) MIBI..
What do you need to know about A sestamibi scan?
A sestamibi scan is a nuclear medicine procedure done for patients with disorders of the parathyroid glands. It is not a diagnostic study or a confirmatory test for the presence of hyperparathyroidism. It is rather done to distinguish or localize the affected gland in a patient already diagnosed with the disease.
How long is a sestamibi scan for parathyroid surgery?
–the highest resolution and most accurate sestamibi scans in the world. Examination Time: Ten minutes to 1 hour (10 to 20 minutes if being performed immediately prior to minimal parathyroid surgery (the MIRP procedure) using intraoperative nuclear mapping…see below) (About 98% of our scans are completed in 20 minutes or less).
What does sestamibi do for a parathyroid adenoma?
Sestamibi will assist the surgeon in localizing a parathyroid adenoma in a three dimensional setting, allowing a more directed operative approach to the parathyroids.
Is the sestamibi scan a diagnostic or diagnostic test?
The Sestamibi scan is a localizing study to find the bad parathyroid gland, NOT a diagnostic study to diagnose parathyroid disease. It is also a functional study as all nuclear medicine tests are.
When is the best time to take sestamibi?
Uses, doses and timings. Parathyroid scan. adult dose: 740 MBq (20 mCi) IV. timing: early scan at 15 min; delayed scan at 2 hours.

How long does it take to take Tc-99m sestamibi?
Tc-99m sestamibi is injected at 85% predicted maximum heart rate and the patient continues to exercise for an additional 60 seconds while the tracer is extracted by the myocardium. The patient is imaged 30-60 minutes later.
