TI  - SIZE-SPECIFIC DOSE ESTIMATES FOR PEDIATRIC NON-CONTRAST HEAD CT SCANS: A 
      RETROSPECTIVE PATIENT STUDY IN TUNJA, COLOMBIA.

AB  - This investigation is aimed to study the feasibility of size-specific dose 
      estimate (SSDE) to patient dosimetry in pediatric head CT scans and to establish 
      typical values in a hospital in Tunja, Colombia. The volumetric computed 
      tomography index (CTDIvol) and the dose-length product of 468 pediatric patients 
      from newborn to 15-year-olds, who underwent non-contrast head CT scans, were 
      collected retrospectively. For 186 cases only, SSDE was estimated using patient 
      attenuated-based size metrics and CTDIvol,16-to-SSDE conversion factors reported 
      in AAPM report 293. Results showed that SSDE is an accurate metric that can be 
      used to establish typical dose values from pediatric head CT scans. Median SSDE 
      values of 33.5, 31.6, 36.2 and 57.9 mGy were established as typical dose values 
      for the 0-<3 months, 3 months-<1 y, 1-<6 y and >/=6 y, respectively, to further 
      assist the optimization process at the hospital. Further studies with more robust 
      data of patients and hospitals should be conducted to establish local and 
      national dose reference levels from pediatric CT scans in Colombia.
