In the case of 99m Tc traces, their wide use results from its ideal lifetime and because it is available from a 99 Mo– 99m Tc generator at low cost, first developed in 1959. 155 99m Tc is widely used in nuclear medicine owing to its nearly ideal nuclear properties. It has a relatively low cost and is conveniently available from commercial 99 Mo/ 99m Tc generators, which has led to the use of

99m Tc is used in nuclear medicine for a wide variety of diagnostic tests and imaging studies, e.g., myocardial perfusion scans, bone scans, and V/Q scans.. Tc-99m DTPA (diethylenetriamine-pentaacetic acid) (aerosol) is one of the technetium agents and is used in VQ imaging. Characteristics photon energy: 140 KeV physical half life: 6 hours biological half life: 1 hour normal distribution: lungs Tc-99m MAG3 (mercaptoacetyltriglycine) is one of the technetium radiopharmaceuticals used in renal imaging. Due to favorable energy and dosimetric characteristics, MAG3 radiolabeled with technetium has replaced the iodide-131 Hippuran for the stu energy NaI scintillation probe for Tc-99m contamination. A survey meter equipped with a G-M pancake/frisker probe (15.5 cm2 surface area) can be used for the detection of gross Tc-99m contamination. • Survey meter equipped with a 1” x 1” or a low-energy NaI scintillat ion probe is preferred for the detection of Tc -99m contamination.

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). Therefore, 99m Tc-duramycin is a potential probe for non-invasive detection of apoptosis in real-time. The aim of this study was to evaluate the value of [99m Tc]duramycin for detecting early apoptotic response in tumors after chemotherapy, thus providing a tool for early prediction of curative effects in tumors.

Technetium-99m dextran (TcDx) was highly stable both in vivo and in vitro. In seven dogs we compared the quality of blood-pool images obtained with TcDx of different molecular weights (4 X 10(4) = Dx-40; 5 X 10(5) = Dx-500; 2 X 10(6) = Dx-2000) and with Tc-99m red blood cells (TcRBC) labeled in vitro, and determined the organ distribution of this new agent by whole-body scanning and blood

Technetium-99m's short half-life of 6 hours makes long-term storage impossible. Transport of 99m Tc from the limited number of production sites to radiopharmacies (for manufacture of specific radiopharmaceuticals) and other end users would be complicated by the need to significantly overproduce in order to have sufficient remaining activity after long journeys.
