AB  - Purpose To develop diagnostic reference levels (DRLs) and achievable doses (ADs) 
      for the 10 most common adult computed tomographic (CT) examinations in the United 
      States as a function of patient size by using the CT Dose Index Registry. 
      Materials and Methods Data from the 10 most commonly performed adult CT head, 
      neck, and body examinations from 583 facilities were analyzed. For head 
      examinations, the lateral thickness was used as an indicator of patient size; for 
      neck and body examinations, water-equivalent diameter was used. Data from 1 310 
      727 examinations (analyzed by using SAS 9.3) provided median values, as well as 
      means and 25th and 75th (DRL) percentiles for volume CT dose index (CTDI(vol)), 
      dose-length product (DLP), and size-specific dose estimate (SSDE). Applicable 
      results were compared with DRLs from eight countries. Results More than 46% of 
      the facilities were community hospitals; 13% were academic facilities. More than 
      48% were in metropolitan areas, 39% were suburban, and 13% were rural. More than 
      50% of the facilities performed fewer than 500 examinations per month. The 
      abdomen and pelvis was the most frequently performed examination in the study 
      (45%). For body examinations, DRLs (75th percentile) and ADs (median) for 
      CTDI(vol), SSDE, and DLP increased consistently with the patient's size 
      (water-equivalent diameter). The relationships between patient size and DRLs and 
      ADs were not as strong for head and neck examinations. These results agree well 
      with the data from other countries. Conclusion DRLs and ADs as a function of 
      patient size were developed for the 10 most common adult CT examinations 
      performed in the United States. ((c)) RSNA, 2017.
