AB  - OBJECTIVE: The objective of the study was to determine whether body weight (BW) 
      can be substituted for body diameters to calculate size-specific dose estimate 
      (SSDE) in the children. MATERIALS AND METHODS: A total of 196 torso computed 
      tomography (CT) studies were retrospectively reviewed. Anteroposterior diameter 
      (D(AP)) and lateral diameter (D(lat)) were measured, and D(AP)+D(lat), effective 
      diameter, SSDE diameter and SSDE(BW) were calculated. Correlation coefficients 
      among body diameters, all SSDE types and percentage changes between CT dose index 
      volumes and SSDEs were analyzed by BW and age subgroups. RESULTS: Overall BW was 
      more strongly correlated with body diameter (r = 0.919-0.960, P < 0.001) than was 
      overall age (r = 0.852-0.898, P < 0.001). The relationship between CT dose index 
      volume and each of the SSDE types (r = 0.934-0.953, P < 0.001), between SSDE(BW) 
      and all SSDE diameters (r = 0.934-0.953, P < 0.001), and among SSDE diameters (r 
      = 0.950-0.989, P < 0.001) overall had strong correlations with statistical 
      significance. The lowest magnitude difference was SSDE(BW)-SSDE(eff). CONCLUSION: 
      BW can be used instead of body diameter to calculate all SSDE types, with our 
      suggested best accuracy for SSDE(eff) and the least variation in age < four years 
      and BW < 20 kg. KEY MESSAGES: Size-specific dose estimate (SSDE) is a new and 
      accurate dose-estimating parameter for the individual patient which is based on 
      the actual size or body diameter of the patient. BW can be an important 
      alternative for all body diameters to estimate size-specific dose or calculate 
      SSDE in children.
