Purpose or learning objective Radiation exposure is a key concern in interventional radiology, both for patients and medical personnel. Real-time dosimetry provides a valuable tool for live monitoring of the radiation exposure of staff during radiological interventions, which offers immediate feedback during procedures and allows detailed dose assessment afterwards.  It can help to increase radiation awareness among staff, evaluate protection measures and optimise procedures to minimise the occupational dose [1-4].  The aim of this study is to  evaluate the feasibility of implementing real-time dosimetry in radiological...
Read more Methods or background Over a period of one month, the radiation exposure of staff during 61 diagnostic and therapeutic radiological interventions at the LMU University Hospital in Munich was measured using a real-time dosimetry system (RaySafe i3, Unfors RaySafe, Sweden) (Fig. 1). [fig 1] The interventions included  25 general radiological angiographies (ANG), 17 angiographies in the cardiac catheterization laboratory (Cath Lab),  11 CT-guided interventions (CTI),  and 8 procedures in neuroradiology (NRAD). For each intervention the dose of every staff member was measured using real-time dosimeters placed at chest height over...
Read more Results or findings Staff members reported no inconvenience associated with wearing real-time dosimeters, indicating the feasibility of the method for routine clinical practice. For general radiological angiographies the median of the total accumulated dose for the intervention team was higher than for all other procedures (Fig. 3). [fig 3] The median doses of physicians across all interventions were higher than that of radiology technicians  (Fig. 4). The median accumulated doses of interventionists were significantly higher than that of every other professional role across all interventions (Fig. 4)....
Read more Conclusion The results of this study showed that real-time dosimetry can be seamlessly integrated into routine clinical practice, allowing live monitoring of the radiation exposure of the medical staff as well as the individual analysis of the dose accumulated over an intervention for each staff member,  the total accumulated dose for the intervention team depends on the type of intervention, with general radiological angiographies having the highest collective radiation exposure (but not the highest exposure for each individual role),  radiation exposure exhibits substantial variations...
