Scope note: Técnica de imagen en la que se usan compuestos marcados con radionúclidos de vida corta emisores de positrones (como carbono-11, nitrógeno-13, oxígeno-15 y flúor-18) para medir el metabolismo celular. Es útil para el estudio de los tejidos blandos como en el CÁNCER, SISTEMA CARDIOVASCULAR y encéfalo. La técnica de TOMOGRAFÍA COMPUTARIZADA POR EMISIÓN DE FOTÓN ÚNICO (SPECT) está estrechamente relacionada con la tomografía por emisión de positrones (PET), pero utiliza isótopos con semividas más largas y su poder de resolución es menor.

Scope note: An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.
