What is the best way to find a parathyroid tumor?
How is a parathyroid tumor diagnosed?
- Blood or urine tests. These can detect high levels of calcium or parathyroid hormone in your body.
- Imaging tests. These include X-rays, ultrasound, CT scans, and MRIs.
- Sestamibi/SPECT scan. This test can show if you have an overactive parathyroid gland.
How do you perform a parathyroid scan?
During your exam, a small amount of radioactive tracer will be injected into a vein in your arm. The tracer allows your parathyroid glands to be seen by the nuclear medicine camera. After 10 minutes, you will be positioned on your back and images will be taken for approximately 20 minutes.
How do you investigate parathyroid adenoma?
Parathyroid adenomas are usually discovered when a higher-than-normal calcium level shows up in a routine blood test, particularly in people without symptoms. Doctors then confirm the diagnosis of primary hyperparathyroidism with a test that shows parathyroid hormone levels in the blood are higher than normal.
How accurate is the sestamibi scan for hyperthyroidism?
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).
What does a sestamibi scan show?

When is a sestamibi scan done?
The initial sestamibi scan of the parathyroid glands is performed within about 10 minutes of injection of the radioactive agent (it’s very important that the first scan is done within 10 minutes otherwise it will not be as accurate).
How do I prepare for a sestamibi scan?
How do I prepare for a sestamibi scan?
