Positron Emission Tomography (PET) – Nuclear Medicine Imaging Technology
Positron emission tomography (PET) is another approach to nuclear medicine imaging that has several advantages over SPECT. PET uses positron-emitting radionuclides that result in the emission of collinear pairs of 511-keV annihilation photons. The coincidence detection of the annihilation photons obviates the need for collimation and makes PET far more efficient than SPECT for detecting […]
