Focal F-18 Fluoro-Deoxy-Glucose Accumulation in the Lung Parenchyma in the Absence of CT Abnormality in PET/CT

Abstract

The finding of significant focal accumulation of fluoro-deoxy-glucose in the lung parenchyma in the absence of corresponding CT abnormality was artifactual. This was likely due to injection technique and the creation of particulate embolus. Positron emission tomography/Computed tomographic readers should be aware of this type of artifact to avoid misinterpretation.
