Tc-99m where m stands for metastable nuclear isomer is used in radioactive isotope medical tests, i.e. radioactive tracer medical equipment used to detect in the body. This is perfect way of detection because the isotope emits detectable gamma rays of 140 ke V. Its half life is about 6.01 hours. As per the Schwochau’s book Technetium, 31 radiopharmaceuticals based on the isotope Technetium 99m. This is used for imaging and functional study of myocardium, thyroid, brain, liver, lungs, gallbladder, skeleton, blood, kidneys and tumors. Due to short time of decay it will eliminate from body with in few days.
Tc-99m used for the treatment called as immunoscintigraphy, in this treatment technetium incorporates in monoclonal body. The resistant system proteins are able to bind cancer cells. After few hours, the equipment detects gamma rays emitted by technetium which are concentrated around tumor. The technique is useful for cancer which is hard to detect and affecting intestine. This anti body are sold by a German company and known as ‘Scintium’.
Tc-99m is capable to combine with red blood cells help to draw circulatory system disorders. Also Tc-99m used to detect gastrointestinal bleeding. |
