| positron emission tomography |
A PET scan creates an image of the body (or of biochemical events) after the injection of a very low dose of a radioactive form of a substance, such as sugar. The scan computes the rate at which the tumor is using the sugar. In general, high-grade tumors use more sugar than normal and low-grade tumors use less. PET scans may also be used to see how well the tumor is responding to treatment

| positron e. |
a form of radioactive decay in which a positron (β+) and neutrino are ejected from the nucleus as a proton is transformed into a neutron. Collision of the positron with an electron causes annihilation of both particles and conversion of their masses into energy in the form of two 0.511 MeV gamma rays.
