title: (18)F-FDG PET hemispheric cerebral hypometabolic activity: patient motion artifact.
abstract: A 51-y-old man underwent (18)F-FDG PET for disease restaging of non-Hodgkin's lymphoma. Initial attenuation correction images demonstrated unilateral hemispheric cerebral hypometabolic activity. The remainder of the scan was otherwise unremarkable. Non-attenuation correction images demonstrated a patient motion artifact attributable to lateral movement of the patient's head during image acquisition. Subsequent repeat (18)F-FDG PET showed normal cerebral cortical activity.
