Bibliometric analysis of global research trends and hotspots on imaging of bladder cancer

Abstract

Purpose To conduct a comprehensive bibliometric analysis of relevant literature on the imaging of BCa and elucidate global research hotspots and further trends in this field. Methods All relevant literature on the imaging of BCa published between January 1, 2000 and July 25, 2023 were retrieved from the Web of Science Core Collection. VOSviewer, Bibliometrix and Citespace were utilized for bibliometric analysis of publications, countries, authors, institutions, journals, references, and keywords. Microsoft Excel was used to draw relevant charts according to the number of publications. Result A total of 4033 articles were retrieved. The research in this field has been increasing consistently since 2000. The USA was the most productive country and most productive institutions were from the USA. Shariat SF was the most productive author with 34 articles and the author with the highest co-citations was Herr HW (418). A study by Siegel RL, published in Ca-Cancer J Clin in 2019, had the highest number of co-citations. Further analysis of the keyword analysis and timeline view revealed that “deep learning”, “MRI”, “VI-RADS”, “muscle-invasive bladder cancer”, “immu-notherapy”, and “lymphatic metastasis” were the most recent hotspots. Conclusion The USA occupies a critical position in this field. The research on imaging of BCa can be classified into two periods: the tumor detection period before 2011 and comprehensive evaluation before treatment decision from 2011 to date. It is anticipated that MRI and deep learning will be the re-search hotspots in this field in the future.
