Abstract Objective To investigate the dose level of pediatric CT scan in one hospital, and to provide recommendations for optimized scanning.Methods The CT scan data of children were collected from this hospital to analyze the differences in typical dose values and typical scanning parameters between different age groups and different scanning parts. Results The sample size was >10 for routine cranial scan, routine maxillary sinus scan, and routine chest scan in each age group, and the 1-year-old group and the 5-year-old group had the same kV, mA, and CTDIvol values of routine cranial scan and maxillary sinus scan, but with relatively great differences in the parameters of chest scan. Conclusion Scanning parameters in this hospital can be further optimized, and optimization measures should be adopted continuously.
