Technetium-99m (Tc-99m) can be readily detected in the body by medical equipment because it emits 140.5 keV gamma rays (these are about the same wavelength as emitted by conventional X-ray diagnostic equipment), and its half-life for gamma emission is six hours (meaning 94% of it decays to 99 Tc in 24 hours). Besides, it emits virtually no beta ...
Technetium 99m Tc albumin aggregated (99m Tc-MAA) is an injectable radiopharmaceutical used in nuclear medicine. It consists of a sterile aqueous suspension of Technetium-99m (99m Tc) labeled to human albumin aggregate particles. It is commonly used for lung perfusion scanning.
The metastable technetium-99m (99m Tc) is a short-lived (half-life about 6 hours) nuclear isomer used in nuclear medicine, produced from molybdenum-99. It decays by isomeric transition to technetium-99, a desirable characteristic, since the very long half-life and type of decay of technetium-99 imposes little further radiation burden on the body.
Technetium (99m Tc) pentetic acid, sold under the brand name Draximage DTPA among others, is a radiopharmaceutical medication used in nuclear medicine to image the brain, kidneys, or lungs. [1] It is given by intravenous injection or via aerosol spray. [ 1 ]
Many radiopharmaceuticals use technetium-99m (Tc-99m) which has many useful properties as a gamma-emitting tracer nuclide. In the book Technetium a total of 31 different radiopharmaceuticals based on Tc-99m are listed for imaging and functional studies of the brain, myocardium, thyroid, lungs, liver, gallbladder, kidneys, skeleton, blood and ...
99m Tc is a very versatile radioisotope, and is the most commonly used radioisotope tracer in medicine. It is easy to produce in a technetium-99m generator, by decay of 99 Mo. 99 Mo → 99m Tc + e − + ν e. The molybdenum isotope has a half-life of approximately 66 hours (2.75 days), so the generator has a useful life of about two weeks.
The most common isotope used in diagnostic scans is Technetium-99m, used in approximately 85% of all nuclear medicine diagnostic scans worldwide. It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems. [1]
Technetium (99m Tc) mertiatide is a radiopharmaceutical medication used in nuclear medicine to image the kidneys. [1] It is a renal imaging agent that is given by intravenous injection. [1] It was approved for medical use in the United States in June 1990. [2]
