To validate a measurement method that assesses patient and operator radiation exposure induced by computed tomography (CT) fluoroscopy assisted vertebroplasty. To assess operator protection device effects on radiation exposure (lead apron, ABM: angle bean modulation)

Assessing radiation exposure on patient and RANDO® phantom, during interventional fluoroscopy procedure (CT Siemens® Somaton 128) for one level percutaneous vertebroplasty, in several locations: under the beam, operator chest, operator extremities, with or without protective devices. Measuring devices are: passive dosimeters (OSL®, Nanodot®), electronic dosimeters (DMC 2000®), radiameters (AT1123®, FH40®, Fluke Victoreen®).

The association of three dosimeters (OSL®, Nanodot®, DMC 2000®) and one radiameter (AT1123®) had best sensibility and reproductibility. Patient effective dose (E) is 42 mSv, operator E is <0,1mSv and 1,8mSv, with or outside lead apron respectively. Extremities dose varies from 5 to 40mSv. Angle Beam Modulation reduce dose about 50%.

We found that patient and operator exposure during CT fluoroscopy guided vertebroplasty is best assessed with an association of three dosimeters and one radiameter with specific locations. This exposure measurement protocol will be used in further studies comparing percutaneous vertebroplasty with CT fluoroscopy vs combined CT and C-arm fluoroscopy guidance.

Evaluation of patient and operator radiation exposure induced by computed tomography (CT) fluoroscopy assisted vertebroplasty.
