Spect isotopes
WebThe isotope is typically applied as iodide -123, the anionic form. Production [ edit] Iodine-123 is produced in a cyclotron by proton irradiation of xenon in a capsule. Xenon-124 absorbs a proton and immediately loses a neutron and proton to form xenon-123, or else loses two neutrons to form caesium-123, which decays to xenon-123. WebWhile SPECT has many applications in neurology and oncology, the majority of SPECTscans are performed in the field of cardiology. SPECT is now a cornerstone with any patient …

WebTechnetium (43 Tc) is one of the two elements with Z < 83 that have no stable isotopes; the other such element is promethium. It is primarily artificial, with only trace quantities existing in nature produced by spontaneous fission (there are an estimated 2.5 × 10 −13 grams of 99 Tc per gram of pitchblende) or neutron capture by molybdenum.The first isotopes to be …
