THE EFFICACY OF RADPAD AS A RADIATION PROTECTION TOOL IN CT FLUOROSCOPY GUIDED LUNG BIOPSIES

Abstract Computed tomography fluoroscopy is now the preferred technique for percutaneous lung biopsies. However, concern regarding operator and patient radiation dose remains, which warrants further exploration into dose optimisation tools. This phantom-study aims to assess the dose reduction capabilities of RADPAD, a single-use patient drape designed to decrease staff exposure to scattered radiation. Dosemeters at the waist and eye levels were used to determine the whole-body and lens exposure during simulated lung biopsy procedures while using RADPAD and other combinations of personal protective equipment. RADPAD resulted in a 36% and 38% dose reduction for whole-body and eye exposure, respectively. However, when used in combination with radioprotective eyewear and aprons, RADPAD did not reduce the radiation dose further. Consequently, the use of standard personal protective equipment is a more cost-effective option for staff dose reduction. RADPAD is useful in the reduction of radiation dose to unprotected regions.
