Real-time dosimetry in interventional radiology – comparing the occupational radiation exposure in fluoroscopy-guided lower extremity and abdominal procedures

Question Active dosimetry facilitates real-time assessment of radiation exposure in different measurement sites, but a multi-dosimeter setup has not been explored for interventional radiology so far. Findings Occupational radiation exposure is considerably higher in abdominal than in lower extremity procedures. Interventionalists' supporting hands receive the highest dose equivalents regardless of procedure type. Clinical relevance Dose monitoring in real time is key to understanding the radiation burden of different anatomical features during image-guided interventions. Especially in dose-intensive abdominal procedures, protective measures are essential to minimize the occupational radiation exposure of the interventionalist.
