Radioisotope emission

WebThe technique needs delivery of a gamma-emitting radioisotope (a radionuclide) into the patient, normally through injection into the bloodstream. On occasion, the radioisotope is a simple soluble dissolved ion, such as an isotope of gallium (III). WebOne of the most current medical investigation is the single-photon emission computed tomography (SPECT) [1]. The injected radioisotope decays with the emission of a single γ photon, by inner electron capture or by isomeric transi-tion. Radiations are captured by scintillation with a camera, which turns around
