ABSTRACT
Objective:To analyze the application and funding status of various projects of nuclear medicine and molecular imaging supported by the National Natural Science Foundation of China (NSFC) from 2013 to 2022, and explore the challenges faced by basic research and clinical transformation in this field.Methods:From 2013 to 2022, application and funding information of nuclear medicine and molecular imaging projects (secondary code H2704, H2706) from five departments of Medical Science Department of NSFC were retrospectively collected. The number of applications, number of funding, funding direction, funding intensity, distribution of supporting units and research hotspots of various projects in this field were analyzed.Results:From 2013 to 2022, the total number of applications of various projects in the field of nuclear medicine and molecular imaging reached 5 387, and the total number of grants reached 899. The number of applications and grants showed a steady growth trend. The overall funding intensity increased from 48.935 0 million yuan in 2013 to 59.495 4 million yuan in 2022, with the increase of 21.58%. Among all supporting units, Shanghai Jiao Tong University topped the list for both the number of applications (440) and the number of grants (82), Xiamen University ranked the first in terms of overall funding rate (25.42%, 30/118), and Peking University ranked the first in terms of total funding intensity (41.897 1 million yuan). Research hotspots focused on the construction of tumor targeted molecular probes and precise imaging of tumor internal molecular components.Conclusion:In the past decade, the number of related projects and total funding of nuclear medicine and molecular imaging supported by NSFC have steadily increased, and the types of funded projects are diverse and interdisciplinary, promoting the innovative development of nuclear medicine and molecular imaging disciplines in China.
