View larger version (7K): [in a new window]   Fig 3. Box plot shows mean radiation exposure rates (microsievert per minute) during cement delivery for each procedure. Significant differences were seen between each procedure (P < .0001), with mean exposure rate being greatest for VP-CDS (2.88 µSv/min).
