  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 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 ...

  5. Technetium-99m - Wikipedia

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

    In the myocardial perfusion scans using 99m Tc, the radiopharmaceuticals 99m Tc-tetrofosmin (Myoview, GE Healthcare) or 99m Tc-sestamibi (Cardiolite, Bristol-Myers Squibb) are used. Following this, myocardial stress is induced, either by exercise or pharmacologically with adenosine , dobutamine or dipyridamole (Persantine), which increase the ...

  6. 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:

  7. 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 ...

  8. 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.

  9. Myocardial perfusion imaging - Wikipedia

    en.wikipedia.org/wiki/Myocardial_perfusion_imaging

    By the late 1980s, two different compounds containing technetium-99m were introduced: teboroxime [10] and sestamibi. The utilization of Tc-99m would allow higher doses (up to 1,100 MBq or 30 mCi) due to the shorter physical (6 hours) half life of Tc-99m.
