摘要: Radionuclide-tracer targeted imaging is based on the detection of gamma rays emitted by radionuclides embedded in biologically specific compounds after injection into human or experimental animals. The most common used for emit rays, which are uncorrelated, and these detected individually singularly imaging; this called single photon imaging. basic devices cameras rotational version, emission computed tomography (SPECT) cameras. Another radionuclide-tracer technique uses positron emitting that two 511-KeV simultaneously, pair simultaneously coincidentally purposes; known as coincidence
