Abstract Objective Randomly selected 17 hospitals in 8 prefecture-level cities in Shandong Province to investigate the frequency of CT examination of children and get a preliminary understanding of the frequency composition.Methods With reference to and modification of the national unified questionnaire on medical irradiation, 17 hospitals in 8 cities in Shandong Province were randomly selected as a sample by stratified random sampling method, the contents of the survey included the level of medical institutions and information on the diagnosis and treatment of examines obtained from the computer information management system, etc.Results A total of 45114 children were surveyed, of whom 27307 (60.53%) were boys and 17807 (39.47%) were girls; 8091 (17.93%) were in the infant group (< 1 year old), 8910 (19.75%) in the toddler group (1～< 3 years old), 7656 (16.97%) in the preschool group (3～< 6 years old), and 20457 children (45.35%) in the adolescent group (10～< 15 years old). The top two cumulative frequencies of irradiation in children of different ages were cranial and thoracic, with 18398 (35.4%) and 15359 (29.5%) irradiation frequencies, respectively. Plain scans were the predominant CT scanning modality, with 45194 (86.87%) scans and 5200 (10.0%) enhanced scans. The top two sites for enhanced scans were cranial and thoracic, accounting for 16.36% and 13.20% of the scans, respectively. Among the different age groups, the highest proportion of repeat examination was the preschool group, with 14.64% having two examinations and 2.49% three examinations; the highest proportion of repeat examinations among the different sites examined was coronary angiography.Conclusion Due to the high frequency of CT scans for children, relevant departments should take strong measures to optimize medical exposure protection and reduce radiation hazards.
