An X-ray lead screen may be used to reduce an interventional radiologist’s radiation exposure during CT-guided procedures

PURPOSE: The exposure of both patient and operator to radiation is one of the limitations of computed tomography (CT)-guided interventions, and it should be kept as low as reasonably possible. The purpose of the study was to evaluate the efficacy of a lead screen in reducing the radiation dose to an...

description PURPOSE: The exposure of both patient and operator to radiation is one of the limitations of computed tomography (CT)-guided interventions, and it should be kept as low as reasonably possible. 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. The presence of the screen caused no discomfort for operators. CONCLUSIONS: A lead screen reduces an operator’s radiation exposure significantly, while not posing any obstacles or causing any discomfort while CT-guided procedures are carried out.
