Tcm-sestamibi is a radiopharmaceutical that is taken up by cells with a high concentration of mitochondria i. This latter technique has a high specificity for cancer but uses significant radiation dose. A thyroid scan using Tcm pertechnetate follows. Parathyroid adenomas do not demonstrate uptake on thyroid scans, whereas normal thyroid tissue does. Tcm sestamibi is the most common agent for performing myocardial perfusion scintigraphy.

We made the Calcium Pro app to make high calcium and parathyroid problems easy to diagnose. Top-3 medical app of , 15, and Read our Parathyroid Blog! Interesting stories about hyperparathyroid patients we see every day. There are some great stories here!
The Sestamibi Scan for Hyperparathyroidism (parathyroid problems).
Medically reviewed by Drugs. Last updated on Feb 27, Information in this record refers to the use of technetium Tc 99m sestamibi Tc 99m-methoxyisobutylisonitrile; Tc 99m MIBI as a diagnostic agent. The United States Nuclear Regulatory Commission and other agencies state that breastfeeding need not be interrupted after administration of technetium Tc 99m sestamibi in doses up to MBq 30 mCi to a nursing mother.
Mammography and ultrasound are common anatomical imaging procedures used to detect breast cancer. While screening mammography, especially when combined with ultrasound, has demonstrated the ability to detect non-palpable breast cancer, these modalities still suffer from some significant limitations. According to the results of the American College of Radiology Imaging Network ARCIN clinical trial, the combination of mammography and ultrasound resulted in a positive predictive value of only Breast-specific Gamma Imaging BSGI , also referred to as molecular breast imaging MBI , scintimammography or mammoscintigraphy, is a nuclear medicine breast imaging technique which has been significantly improved within recent years with the invention of breast optimized gamma camera designs. Prior to this development, such studies were generally conducted with standard, large fieldof-view LFOV gamma cameras.
