A technetium-99m generator, or colloquially a technetium cow is a device used to extract the metastable isotope 99m Tc of technetium from a source of decaying molybdenum-99. 99 Mo has a half-life of 66 hours and can be easily transported over long distances to hospitals where its decay product technetium-99m (with an inconvenient half-life of only 6 hours for transport) is extracted and used Technetium-99m (99m Tc)–labeled pentavalent dimercaptosuccinic acid ([99m Tc]-(V)DMSA) has been used for renal scintigraphy (see below for references) as well as detection and postoperative evaluation of medullary carcinomas of the thyroid (MCT).[99m Tc]-(V)DMSA has been shown to accumulate in breast tumors, head and neck cancers, osteosarcomas, and hepatocellular carcinoma (1). Background: Technetium pyrophosphate (99m Tc-PYP) imaging to diagnose transthyretin cardiac amyloidosis (ATTR-CA) has been increasingly utilized. The objective of this study is to provide a standardized 99m Tc-PYP imaging protocol to diagnose ATTR-CA.. Methods: 104 scans from 45 subjects with biopsy-proven ATTR-CA or light-chain cardiac amyloidosis (AL) were assessed. Technetium 99m. Technetium-99m is the most commonly used radioisotope in single photon emission computed tomography (SPECT).

Tc-99m, the decay product of molybdenum-99 (Mo-99), is the perfect fit for medical imaging. It emits gamma rays with an energy of 140 keV, which can easily be detected using a standard gamma camera. A relatively short physical half-life of six hours, and a biological half-life of one day, makes Tc-99m ideal for use in procedures such as single-photon emission computed tomography (SPECT).
