Abstract：Objective To analyze the development status of high-end magnetic resonance imaging (MRI) in the world from the
perspective of patent application, and put forward targeted countermeasures and suggestions for domestic development.
Methods incoPat was used to analyze the global high-end MRI patents from 2013 to 2022, and the retrieved patents were analyzed
from the perspective of the quantity, quality and research direction of patent applications, and the research situation of high-end MRI
technology at home and abroad was discussed. Results A total of 6087 patent applications related to high-end MRI were retrieved
worldwide. From the perspective of the number of patent applications, the number of applications in China ranked first in the world,
accounting for 1949, 32% of the world, but from the perspective of patent application quality, the application authorization rate
in China was slightly lower, about 53.82%. The global’s high-end MRI mainly includes six technical directions: ultra-high field
MRI, hyperpolarized MRI, ultra-fast MRI of deep learning post-processing, multi-core MRI, AI+MRI and PET/MRI multi-modal
integrated imaging. Chinese ultra-high field, deep learning and AI, multi-core and hyperpolarized MRI research and development
capabilities were in the forefront of the world, among which the Chinese Academy of Sciences was the main contributor. However, Chinese
PET/MRI integrated MRI research and development strength was weak, which needed to be further strengthened.
Conclusion Domestic enterprises should strengthen cooperation with Chinese Academy of Sciences and universities, apply national
scientific research projects to the industry, promote the transformation of scientific research results, form complementary advantages,
and improve the discourse power of China in the field of high-end MRI.
