Abstract Objective To estimate the application frequency of medical X-CT and the collective effective dose in Fujian province in 2016.Methods By randomly sampling, 30 hospitals from 9 cities in Fujian province were investigated. The application information was read out from the Medical Image Archiving and Communication System (PACS) in each hospital. For the dose survey, DICOM files for 615 examinees were read out. The provincial application frequency and collective dose were estimated using population information.Results There were 72 sets of CT in the sampled hospitals, and they performed 1 556 514 times of examinations throughout a year. The application frequency of CT examination in Fujian province was estimated to be 311.6 person·times per 1 000 population, and the collective effective dose was estimated to be 8 776 person·Sv in 2016.Conclusion The application frequency of medical X-CT in Fujianprovince in 2016 significantly increased by compared to the national level in the Ninth Five-year Plan. Adjust CT scan parameters could decrease the patient dose effectively.
