WebDec 17, 2024 · Positron emission tomography, also known as a PET scan, produces 3D color images of processes within the human body. Doctors often use PET scans to diagnose a condition or track its progression. WebPositron emission is observed for nuclides in which the n:p ratio is low. These nuclides lie below the band of stability. Positron decay is the conversion of a proton into a neutron with the emission of a positron. The n:p ratio increases, and the daughter nuclide lies closer to the band of stability than did the parent nuclide.
