Abstract:
Objective:To investigate devices for radiodiagnosis used in medical institutions in Beijing, China, as well as radiation workers and the devices′ application frequencies, in order to provide data support for determining radiation protection measures and allocating resources for clinical radiodiagnosis.Methods:In October 2023, questionnaires were distributed to the members of the Radiation Technology Branch of the Beijing Medical Association who work in medical institutions at different levels across varying districts of Beijing. The collected data included information about devices for radiodiagnosis and radiation workers, as well as the application frequencies of various medical X-ray imaging devices during 2018-2022, in 38 medical institutions of Level 3 Grade A, Level 3, and Level 2 in 14 municipal districts of Beijing. Then, the collected data were organized using the Microsoft Power BI software to form report models, followed by the statistical analysis of data on the devices, radiation workers, and application frequencies were using the RStudio software.Results:The 38 medical institutions in Beijing possess 591 devices for radiodiagnosis and 2 018 staff in the departments of radiology, including 1 037 radiologic technologists and 738 physicians, with 1.77 technologists and 1.26 physicians arranged for a single device on average. From 2018 to 2022, among all examinations of radiodiagnosis, computed tomography (CT) scans showed the highest frequencies, with total and average annual growth rates of 138.06% and 108.40%, respectively. Specifically, chest CT scans exhibited total and average annual growth rates of 225.20% and 122.50%, respectively. X-ray imaging ranked second in application frequency, with total average annual growth rates of 70.20% and 91.53%, respectively. Notably, chest X-ray imaging showed total and average annual growth rates of 63.89% and 89.41%, respectively.Conclusions:From 2018 to 2022, X-ray imaging examinations displayed significantly fluctuating frequencies with an overall decline trend in the 38 medical institutions. In contrast, the CT scans showed increased frequencies, with chest CT scans displaying an increased frequency and proportion. This necessitates ensuring the justification of CT scans.
