Local diagnostic reference levels for skeletal surveys in suspected physical child abuse

Introduction The purpose was to determine if an age based, local diagnostic reference level for paediatric skeletal surveys could be established using retrospective data. Methods All children below two years of referred a primary survey as result suspected physical abuse during 2017 or 2018 (n = 45) were retrospectively included from large Danish university hospital. protocol total 33 images. Dose Area Product (DAP) and acquisition parameters all images recorded the Picture Archival Communication System (PACS) effective dose estimated. 75th percentile DAP considered (DRL). Results 314 mGy∗cm2, 520 mGy∗cm2 779 <1 month, 1–11 months 12 < 24 respectively. However, only group had sufficient number 27) establish DRL. Thus, other groups must interpreted with caution. Effective 0.19, 0.26 0.18 mSv <1, Conclusion For between 1 11 age, determined. This may used initial benchmark comparison future discussion. Implications practice While data presented reflects results single department, suggested departments when auditing radiation dose.
