Research hotspots and development trends in molecular imaging of glioma (2014-2024): A bibliometric review.

BACKGROUND

This study aims to explore research hotspots and development trends in molecular imaging of glioma from 2014 to 2024.

METHODS

A total of 2957 publications indexed in the web of science core collection (WoSCC) were analyzed using bibliometric techniques. To visualize the research landscape, co-citation clustering, keyword analysis, and technological trend mapping were performed using CiteSpace and Excel.

RESULTS

Publication output peaked in 2021. Emerging research trends included the integration of radiomics and artificial intelligence and the application of novel imaging modalities such as positron emission tomography and magnetic resonance spectroscopy. Significant progress was observed in blood-brain barrier disruption techniques and the development of molecular probes, especially those targeting IDH and MGMT mutations.

CONCLUSION

Molecular imaging has been pivotal in advancing glioma research, contributing to improved diagnostic accuracy and personalized treatment strategies. However, challenges such as clinical translation and standardization remain. Future studies should focus on integrating advanced technologies into routine clinical practice to enhance patient care.
