An intense 18F-FDG pulmonary microfocus on PET without detectable abnormality on CT: a manifestation of an iatrogenic FDG pulmonary embolus

An incidental finding of an intense focus of 18F-Fluorodeoxyglucose (FDG) pulmonary uptake on positron emission tomography (PET) without detectable lesions on computed tomography (CT) is highly suggestive of FDG microembolus. Its microscopic nature means it is undetectable on CT. It is an artefact a...
