A Bibliometric and Trend Analysis of Publications in Journal of Vascular and Interventional Radiology and...

To show that interventional radiology (IR) research output demonstrates regional disparities in productivity and citation impact, with distinct thematic trends driven by technological advancements.

This systematic review investigated the global scientific publications, citation impact, and thematic focus in IR between 2014 and 2025, highlighting key contributors, influential articles, and prevailing research topics in the field. Data on scientific publications were collected from 2 major journals, CardioVascular and Interventional Radiology and the Journal of Vascular and Interventional Radiology. Scientific publications by country and citation metrics were assessed, and a keyword analysis was performed to identify trends in research focus.

The bibliometric analysis of 7,361 studies (2014-2025) revealed that the United States accounted for the largest share of scientific output (3,135 publications) and total citations (15,869), followed by China, Germany, France, and Japan. The most productive institutions included Mayo Clinic, University of Ulsan College of Medicine, and Northwestern University. Although embolization, ablation, and hepatocellular carcinoma remained the most frequently studied themes, there was a clear upward trend in studies involving artificial intelligence, robotics, and advanced ablation modalities, suggesting a shift toward data-driven and precision technologies.

The findings support the hypothesis of regional variation and thematic evolution in IR research. The United States had the highest number of publications in IR research, followed by Europe and Asia, reflecting a diverse and global research landscape. The field emphasizes oncologic interventions, especially for liver-related conditions. Research on artificial intelligence, robotics, and advanced ablation technologies features prominently as emerging topics in the field.
