Real-Time Patient and Staff Radiation Dose Monitoring in IR Practice

Abstract

PurposeKnowledge of medical radiation exposure permits application of radiation protection principles. In our center, the first dedicated real-time, automated patient and staff dose monitoring system (DoseWise Portal, Philips Healthcare) was installed. Aim of this study was to obtain insight in the procedural and occupational doses.Materials and MethodsAll interventional radiologists, vascular surgeons, and technicians wore personal dose meters (PDMs, DoseAware, Philips Healthcare). The dose monitoring system simultaneously registered for each procedure dose-related data as the dose area product (DAP) and effective staff dose (E) from PDMs. Use and type of shielding were recorded separately. All procedures were analyzed according to procedure type; these included among others cerebral interventions (n = 112), iliac and/or caval venous recanalization procedures (n = 68), endovascular aortic repair procedures (n = 63), biliary duct interventions (n = 58), and percutaneous gastrostomy procedure (n = 28).ResultsMedian (±IQR) DAP doses ranged from 2.0 (0.8–3.1) (percutaneous gastrostomy) to 84 (53–147) Gy cm2 (aortic repair procedures). Median (±IQR) first operator doses ranged from 1.6 (1.1–5.0) μSv to 33.4 (12.1–125.0) for these procedures, respectively. The relative exposure, determined as first operator dose normalized to procedural DAP, ranged from 1.9 in biliary interventions to 0.1 μSv/Gy cm2 in cerebral interventions, indicating large variation in staff dose per unit DAP among the procedure types.ConclusionReal-time dose monitoring was able to identify the types of interventions with either an absolute or relatively high staff dose, and may allow for specific optimization of radiation protection.

Radiation dose reduction capabilities of a new C-arm system with optimized hard- and software

“…Radiation exposure for the patient during image-guided interventional procedures can be considerable, especially due to digital subtraction angiography (DSA), and the implications of radiation are well known [1][2][3]. In addition, the clinical staff performing the procedures is exposed to radiation as well, and the awareness for the radiation impact on the health of the clinical staff has increased over the last decade, resulting in the development real time dose monitoring systems for clinical staff [4]. Especially for patients undergoing repeated procedures, the cumulative radiation dose is even higher [5].…”

IS Trans-Radial Approach Related to an Increased RisK of RAdiation Exposure In Patients Who Underwent Diagnostic CoronaRY Angiography or Percutaneous Coronary Intervention? (The SAKARYA Study)

“…This could be argued because a similar result for patients and operators with regard to radiation exposure was demonstrated in the RAD-Matrix trial (20). Moreover, a strong correlation between procedural DAP and reference personal dosimeter dose was demonstrated by Sailer et al (24). Furthermore, Brasselet et al (25) and Kuipers et al (26) revealed strong correlations between patient and operator exposure.…”

Development of air pressure mirroring particle dispersion method for producing high-density tungsten medical radiation shielding film

“…Recently, in the medical field, with the development of preventive medicine, the number of tests using medical radiation has increased significantly; hence, exposure to medical radiation is also increasing 15 . There are three factors for radiation defense: time, distance, and shielding, but active shielding is the best way for protecting healthcare professionals working with patients 16 .…”
