ABSTRACT

@#<b>Objective</b> To investigate radiation resources in medical diagnosis and treatment and their use frequency in medical institutions in Hangzhou, China, and to provide a basis for relevant departments to rationally allocate and scientifically supervise the resources. <b>Methods</b> From April 1, 2019 to March 31, 2020, a survey was conducted on the basic information, radiation staff, equipment configuration, and frequency of radiation diagnosis and treatment of all medical institutions in Hangzhou using a questionnaire. <b>Results</b> There were 1001 institutions with radiation services in Hangzhou, with 6714 radiation staff members and 2742 pieces of radiation equipment. The frequency of conventional X-ray diagnosis was 788.43 per 1000 population. The frequency of computed tomography diagnosis was 531.93 per 1000 population. The frequency of mammography and dental photography diagnosis was 246.34 per 1000 population. The frequency of interventional diagnosis and treatment was 10.01 per 1000 population. The frequency of radiotherapy was 2.39 per 1000 population. The frequency of nuclear medicine diagnosis was 8.90 per 1000 population. The frequency of nuclear medicine treatment was 0.99 per 1000 population. <b>Conclusion</b> Medical institutions have developed rapidly in Hangzhou, but with an unbalanced situation. In order to better protect the health of examinees, we recommend relevant departments optimize resource allocation and strengthen supervision on radiation protection in medical institutions.
