ABSTRACT
Positron emission tomography is an imaging technique based on the use of radiopharmaceuticals. The most extended one is the glucose analogue 18F fluorodeoxyglucose (FDG) that is deposited where there is an increase of glycolytic metabolism, whether this is caused by neoplastic, inflammatory or infectious diseases. It is used in oncology for the initial staging, to assess response to treatment, residual disease, recurrent diagnosis and restaging, but specifically among the different types of tumor. It also has a field in the study of large vessel vasculitis, in granulomatous diseases and in dementias.

La tomografía por emisión de positrones es una técnica de imagen basada en la utilización de radiofármacos. El más extendido es la 18F fluorodeoxiglucosa (FDG) análogo de la glucosa que es captado allá donde hay un aumento del metabolismo glucolítico, ya sea originado por enfermedades neoplásicas, inflamatorias o infecciosas. Esto hace que sea una técnica muy sensible. En oncología es utilizada para la estadificación inicial, para valorar la respuesta al tratamiento, la enfermedad residual, el diagnóstico de recidiva y la reestadificación, pero con particularidades entre los distintos tipos de tumor. También tiene campo en el estudio de las vasculitis de grandes vasos, en las enfermedades granulomatosas y en las demencias
