Factors affecting radiation exposure dose in nursing staff during (18)F-fluorodeoxyglucose positron emission tomography/computed tomography.

Objectives: We evaluated factors associated with increased radiation exposure dose in nursing staff who assisted patients with (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT) examinations.

Methods: The Barthel Index and Mini-Mental State Examination (MMSE) score were obtained before PET/CT examinations in 193 patients (mean age ± SD, 77.7 ± 8.
