Strauss KJ, et al. - Using data from the National Radiology Data Registry, researchers conducted a retrospective study of doses to test the premise that academic pediatric CT facilities have optimized CT protocols that may result in a lower and less variable radiation dose in children. For this investigation, 3 examination types were assessed: brain without contrast enhancement, chest without contrast enhancement, and abdomen-pelvis with intravenous contrast enhancement. Investigators found that mean size-specific dose estimate (SSDE) was 51% of the facility’s adult dose for the smallest patients in nonacademic adult facilities. They observed that academic pediatric facilities use lower radiation dose than nonacademic pediatric or adult facilities for all brain CT examinations and for the majority of the chest and abdomen-pelvis CT examinations.
