    of the most beneficial uses are in the field of medicine. Technetium‚ more specifically technetium-99m‚ is used in tens of millions of medical diagnostic procedures annually‚ making it the most commonly used medical isotope. Technetium-99m (99mTc) is favoured because of its half-life being short‚ the energy of the gamma ray it emits‚ and the ability of technetium to be chemically bound to many biologically active molecules (Technetium‚ 2011).

    Radioisotopes are radioactive isotopes of an element. An isotope is an element’s atom that has the same number of protons and electrons‚ but a different number of neutrons‚ causing the atom to be unstable. With radioisotopes‚ they can occur naturally‚ but most often are formed artificially by altering the atom. Scientists measure the rate of which radioisotopes decay at by using the term half-life. This refers to when one-half of the radioactive material has decayed. When the word radioactive comes

    such as a computer to interpret the information detected by the screening to for the image needed. With this application the target tissue must absorb the compound that contains the isotope; one of the most popular used isotopes for scans is Technetium -99m‚ this isotope last only for a period of time. Positron emission tomography (PET) is another technique used. With the radiation therapy this is the method used to treat cancers‚ to apply this treatment a boron-11 isotope solution is placed within

    present some of beneficial applications of radioactivity. • Probably the most significant usage of radioactivity is in medicine. It is used in diagnostic scintigraphy‚ which is a study to asses organ function. Most frequently used‚ isotope of technetium-99m allows the quick removal of the radioisotope from the body and minimizes the risk of possible complications. Unlike X-ray studies‚ which better illustrates the structure of the organ‚ scintigraphy allows accurate diagnosis of its activities and

    and classical radiotracers for CBF measurement in absolute units using SPECT []. Nevertheless‚ the poor spatial resolution and the requirement for dedicated instrumentation have limited its use. Thus‚ brain perfusion retention radiotracers using 99m technetium (99mTc) and iodine 123 (123I) labeled compounds are most common in clinical settings. Given the relatively high cost of 123I as a cyclotron-produced radioisotope‚ the use of radiotracers using 123I is limited as compared to 99mTc labeled compounds
