Measurement of Exposure Dose and Its Reduction Design for Nurses in Charge in FDG-PET/CT with Contrast Reviewing the Manual and Staff Flow Line

Abstract

Nurses in charge received additional radiation exposure from the patients with intravenous FDG injection when FDG-PET/CT with contrast media was performed. The exposure dose was measured about 1.5μSv per examination on average. There was not a large difference among those when the mean exposure dose of each nurse was compared. There was a tendency that the exposure dose was less, as work years of the nurses in charge of PET/CT with contrast were longer. Consideration of radioactivity distribution in the PET/CT examination room has a potential to reduce radiation exposure dose of the nurses in charge.
