ABSTRACT
PET/CT is a common imaging modality used in the evaluation of oncology patients. While being extremely sensitive to identifying sights of malignancy F18FDG is very non-specific. We attempted to provide a brief review of some of the more common processes that a nuclear radiology physician may encounter in daily clinical practice that could result in a false positive diagnosis with F18FDG PET/CT. A fundamental understanding of the limitations of this technology by the interpreting physician is necessary to avoid making inaccurate diagnosis and potentially limiting important treatments for our patients.
RESUMO
PET/CT é uma modalidade de imagem usada para avaliação de pacientes oncológicos. Embora seja extremamente sensível para identificar sinais de malignidade, o F18FDG não é ainda muito específico. Nós buscamos mostrar uma breve revisão de alguns dos processos mais comuns que um médico nuclear pode encontrar na prática clínica diária que poderia resultar em um diagnóstico falso positivo com a F18FDG PET/CT. Uma melhor compreensão das limitações dessa tecnologia é necessária para que a interpretação pelo médico não possibiite diagnósticos imprecisos, que potencialmente podem limitar os tratamentos dos pacientes.
