Excretion of technetium 99m hexakismethoxyisobutylisonitrile in milk
European Journal of Nuclear Medicine, 1991The amount of radioactivity excreted in breast milk following the administration of technetium 99m hexakismethoxyisobutylisonitrile (99mTc-MIBI) to a patient referred for cold spot myocardial scintigraphy was determined. During the first 24 h after administration, only 41.2 kBq 99mTc (0.0084% of the injected dose) was excreted in 448 ml milk with the ...

Scintigraphic techniques are routinely used for the evaluation of the extent and severity of inflammatory bowel disease. Currently, the radiopharmaceutical of choice is 99mTc-hexamethyl propyleneamine oxime (HMPAO)-leukocytes. We studied the imaging potential of two recently developed 99mTc-labeled agents, polyethylene glycol (PEG)-coated liposomes and

Technetium-99m chelates as radiopharmaceuticals
1996Technetium-99m (99mTc) is currently, and will be in the foreseeable future, the most widely used radionuclide used in virtually all clinical diagnostic Nuclear Medicine laboratories in the world. Several 99mTc radiopharmaceuticals that are routinely used have become important factors in decisions on the diagnosis and treatment of patients with a ...

Technetium-99m-MIBI Uptake in Bone Metastases
Journal of Women's Imaging, 2005Aim: The purpose of this study was to determine the potential of Tc-99m hexakis-2-methoxyisobutylisonitrile (MIBI) for detection of bone metastases in breast cancer patients in comparison to Tc-99m methylene diphosphonate (MDP) bone scans. Materials and Methods: Tc-99m MIBI and Tc-99m MDP scans were performed in 55 patients with breast cancer and ...

Technetium‐99m radiochemistry for pharmaceutical applications
Journal of Labelled Compounds and Radiopharmaceuticals, 2017Technetium‐99m (99mTc) is a widely used radionuclide, and the development of 99mTc imaging agents continues to be in demand. This overview discusses basic principles of 99mTc radiopharmaceutical preparation and design and focuses on the 99mTc radiochemistry relevant to its pharmaceutical applications. The 99mTc complexes are described based on the most

Bifunctional Chelators for Technetium-99m
1996Technetium-99m has nearly optimal characteristics as a radionuclide for diagnostic radiopharmaceuticals: (1) a low radiation dose to the patients due to the absence of a-and β-radiation and the short physical half-life (6.02 h), (2) the excellent quality of its scintigraphic images as a result of the favourable energy of its gamma radiation (140.5 keV)
