TI  - ACCURACY OF SIZE-SPECIFIC DOSE ESTIMATE CALCULATION FROM CENTER SLICE IN COMPUTED 
      TOMOGRAPHY.
PG  - 8-19
LID - 10.1093/rpd/ncx069 [doi]
AB  - To evaluate the accuracy of size-specific dose estimate (SSDE) calculation from 
      center slice with water-equivalent diameter (Dw) and effective diameter (Deff). A 
      total of 1812 CT exams (1583 adult and 229 pediatric) were included in this 
      retrospective study. Dw and Deff were automatically calculated for all slices of 
      each scan. SSDEs were calculated with two methods: (1) from the center slice; and 
      (2) from all slices of the volume, which was regarded as the reference standard. 
      Impact of patient weight, height and body mass index (BMI) on SSDE accuracy was 
      assessed. The mean difference between overall SSDE and the center slice approach 
      ranged from 2.0 +/- 1.7% (range: 0-15.5%) for pediatric chest to 5.0 +/- 3.2% 
      (0-17.2%) for adult chest CT. Accuracy of the center slice SSDE approach 
      correlated with patient size (BMI: r = 0.15-0.43; weight r = 0.26-0.49) which led 
      to SSDE overestimation in small and underestimation in large patients. SSDE 
      calculation using the center slice leads to an error of 2-5%; however, SSDE is 
      underestimated in large patients and overestimation in small patients.
