Abbreviation for the examination of positron emission tomography. This test is characterized by the infusion of a weakly radioactive substance into the bloodstream, whose distribution through the body is measured by equipment. This equipment reconstructs the image of the organism and identifies the regions of the body according to the degree of uptake of the radioactive substance.

In oncology, substances captured by cells with a high proliferation rate are usually injected. Thus, areas with high uptake usually correspond to sites of neoplasm. In oncology, PET scanning has been indicated in specific cases, most commonly to confirm or rule out the presence of cancer in areas showing dubious changes in other radiological exams.
