The purpose of the study was to evaluate the efficacy of a lead screen in reducing the radiation dose to an operator in the course of CT-guided interventions. Material and methods This prospective study analysed data collected from 72 consecutive CT-guided procedures, all of which were performed with an X-ray protective lead screen placed between the scanner and the operator. Five dosimeters were placed in the CT scanning room, and accumulated radiation doses were measured for each dosimeter. Results The dosimeter placed on the gantry side of the lead screen revealed highest levels of radiation (11.33 ± 1.93 mSv), which were significantly higher than those at all other dosimeters. The radiation dose behind the lead screen was almost the same when measured by dosimeters on the CT scanner gantry side and 3 metres away from it.
