2. Technetium (99mTc) sestamibi - Wikipedia

   en.wikipedia.org/wiki/Technetium_(99mTc)_sestamibi

   The parathyroid gland takes up 99m Tc MIBI following an intravenous injection, and the patient's neck is imaged with a gamma camera to show the location of all glands. A second image is obtained after a washout time (approximately 2 hours), and mitochondria in the oxyphil cells of the abnormal glands retaining the 99m Tc are seen with the gamma ...

3. Sestamibi parathyroid scan - Wikipedia

   en.wikipedia.org/wiki/Sestamibi_parathyroid_scan

   Theoretically, the hyperfunctioning parathyroid gland will take up more of the Tc99m-sestamibi, and will show up 'brighter' than the other normal parathyroid glands on the gamma camera pictures, especially because of the internal biofeedback loop within the body with calcium inherently feeding back to calcium-receptors and inhibiting ...

4. Parathyroid carcinoma - Wikipedia

   en.wikipedia.org/wiki/Parathyroid_carcinoma

   Parathyroid carcinoma is a rare cancer resulting in parathyroid adenoma to carcinoma progression. [1] It forms in tissues of one or more of the parathyroid glands (four pea-sized glands in the neck that make parathyroid hormone (PTH). PTH helps the body maintain normal levels of serum calcium by promoting calcium reabsorption from bone.

5. Technetium-99m - Wikipedia

   en.wikipedia.org/wiki/Technetium-99m

   Technetium-99m (99m Tc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world.

6. Single-photon emission computed tomography - Wikipedia

   en.wikipedia.org/wiki/Single-photon_emission...

   A cardiac specific radiopharmaceutical is administered, e.g., 99m Tc-tetrofosmin (Myoview, GE healthcare), 99m Tc-sestamibi (Cardiolite, Bristol-Myers Squibb) or Thallium-201 chloride. Following this, the heart rate is raised to induce myocardial stress, either by exercise on a treadmill or pharmacologically with adenosine , dobutamine , or ...

7. Parathyroid adenoma - Wikipedia

   en.wikipedia.org/wiki/Parathyroid_adenoma

   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 radiopharmaceutical 68 Ga-Trivehexin [ 8 ] has demonstrated a higher detection rate (94.1%) than 99m Tc-sestamibi ...

8. Sestamibi scan - Wikipedia

   en.wikipedia.org/wiki/Sestamibi_scan

   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:

9. Radiopharmacology - Wikipedia

   en.wikipedia.org/wiki/Radiopharmacology

   Many radiopharmaceuticals use technetium-99m (Tc-99m) which has many useful properties as a gamma-emitting tracer nuclide. In the book Technetium a total of 31 different radiopharmaceuticals based on Tc-99m are listed for imaging and functional studies of the brain, myocardium, thyroid, lungs, liver, gallbladder, kidneys, skeleton, blood and ...
