Abstract:
Objective To investigate the basic situation of nuclear medicine diagnostic and treatment institutions in Shanghai, understand the development level and distribution characteristics of nuclear medicine in Shanghai, and assess the current status of nuclear medicine development in Shanghai. Methods Using questionnaires, on-site verification, and retrieval of information system records, a survey was carried out on nuclear medicine department staff, equipment, and personal radiation exposure levels of workers in Shanghai. Results As of December 2023, there were 48 nuclear medicine diagnostic and treatment institutions in Shanghai, including 32 (66.7%) tertiary hospitals. Of these, 24 (50%) hospitals performed 131I therapy, and 9 (18.8%) hospitals conducted 131I treatment for thyroid cancer. There were 681 nuclear medicine radiation workers, with an average annual effective dose from external radiation of 0.54 mSv. There were 137 pieces of nuclear medicine equipment, including 56 SPECT/CT, 42 PET/CT, 8 PET/MRI, 25 thyroid function meters, and 6 cyclotrons. In 2023, the total radioactivity of radionuclides used in Shanghai was 1.2 × 108 MBq, with 3.4 × 107 MBq of 18F, 7.4 × 107 MBq of 99mTc, and 1.2 × 107 MBq of 131I. The total annual number of nuclear medicine diagnostic and treatment procedures performed was 247 826 and the application frequency was 10.0 procedures per thousand population. Conclusion Clinical nuclear medicine in Shanghai has developed rapidly, achieving the Level I healthcare standard as defined in the UNSCEAR 2008 report. Enhancing occupational protection for radiation workers is a critical issue that requires particular attention in the next phase of development.
