AB  - Background The American College of Radiology Dose Index Registry for CT enables 
      evaluation of radiation dose as a function of patient characteristics and 
      examination type. The hypothesis of this study was that academic pediatric CT 
      facilities have optimized CT protocols that may result in a lower and less 
      variable radiation dose in children. Materials and Methods A retrospective study 
      of doses (mean patient age, 12 years; age range, 0-21 years) was performed by 
      using data from the National Radiology Data Registry (year range, 2016-2017) (n = 
      239 622). Three examination types were evaluated: brain without contrast 
      enhancement, chest without contrast enhancement, and abdomen-pelvis with 
      intravenous contrast enhancement. Three dose indexes-volume CT dose index 
      (CTDI(vol)), size-specific dose estimate (SSDE), and dose-length product 
      (DLP)-were analyzed by using six different size groups. The unequal variance t 
      test and the F test were used to compare mean dose and variances, respectively, 
      at academic pediatric facilities with those at other facility types for each size 
      category. The Bonferroni-Holm correction factor was applied to account for the 
      multiple comparisons. Results Pediatric radiation dose in academic pediatric 
      facilities was significantly lower, with smaller variance for all brain, 42 of 54 
      (78%) chest, and 48 of 54 (89%) abdomen-pelvis examinations across all six size 
      groups, three dose descriptors, and when compared with that at the other three 
      facilities. For example, abdomen-pelvis SSDE for the 14.5-18-cm size group was 
      3.6, 5.4, 5.5, and 8.3 mGy, respectively, for academic pediatric, nonacademic 
      pediatric, academic adult, and nonacademic adult facilities (SSDE mean and 
      variance P < .001). Mean SSDE for the smallest patients in nonacademic adult 
      facilities was 51% (6.1 vs 11.9 mGy) of the facility's adult dose. Conclusion 
      Academic pediatric facilities use lower CT radiation dose with less variation 
      than do nonacademic pediatric or adult facilities for all brain examinations and 
      for the majority of chest and abdomen-pelvis examinations. (c) RSNA, 2019 See also
