Abstract

ABSTRACT The complexity of the pathological reactions of the brain to an aggression caused by an internal or external noxa represents a challenge for molecular imaging. Positron emission tomography (PET) can indicate in vivo,anatomopathological changes involved in the development of different clinical symptoms in patients with neurodegenerative disorders. PET and the multitracer concept can provide information from different systems in the brain tissue building an image of the whole disease. We present here the combination of 18F-flourodeoxyglucose (FDG) and N-[11C-methyl]-L-deuterodeprenyl (DED), FDG and N-[11C-methyl] 2-(4'-methylaminophenyl)-6-hydroxybenzothiazole (PIB), PIB and L-[11C]-3'4-Dihydrophenylalanine (DOPA) and finally PIB and [15O]H2O.RESUMO A complexidade das reações patológicas do cérebro à agressões causadas por noxa interna ou externa representa um desafio para a imagem molecular. Tomografia por emissão de positron (PET) pode indicar, in vivo, alterações anatomopatológicas envolvidas no desenvolvimento de diferentes sintomas clínicos em pacientes com desordens neurodegenerativas. PET e o conceito de multitraçador pode fornecer informações de diferentes sistemas no tecido cerebral, construindo assim uma imagem da doença como um todo.
