@#<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.
