About Infection & Inflammation Imaging
Finding the sourcewhen it is not clear.
Infection and inflammation increase glucose use in the affected tissue, which FDG PET-CT can show across the whole body in one study. NaF PET-CT instead shows areas of active bone change. The tracer is chosen according to your clinical question.
Infection & inflammation
FDG and FDG-labelled leukocyte PET-CT help locate infection or inflammation, including when the cause of a prolonged fever is not known.
Skeletal imaging
NaF PET-CT shows areas of increased bone activity and may help in assessing the skeleton in selected clinical situations.
Your doctor will advise which study is appropriate for your clinical question.
