The Role of FDG PET/CT in the Investigation of Pyrexia of Unknown Origin
A critical appraisal of the role of FDG PET in Pyrexia of Unknown Origin (PUO) depends on an understanding of current concepts of PUO and systematic review of available evidence. This chapter provides an introduction to case definitions of PUO and summarises the current evidence, reviews available guidelines and discusses limitations in the application of FDG PET/CT for investigation of PUO.
