Tracing global inequities in radiology research: a multi-level analysis of research output.
Background: Authorship disparities in medical research are evident, particularly between high-income countries (HICs) and low- and middle-income countries (LICs/LMICs). These disparities have been analyzed in recent publications in Pediatric Radiology journal, noting that between 2019 and 2022, no manuscripts from LICs and only 13 manuscripts from LMICs were published. To our knowledge, an extensive review of publication trends in Pediatric Radiology journal and in radiology word containing journals, with regard to LICs/LMICs disparities, is currently lacking.
Objective: The objective was to assess historical trends and regional disparities in radiology research output and impact.
Materials and methods: A three-pronged approach was used: (1) analysis of all original articles and reviews in Pediatric Radiology (1973-2024), distinguishing LMIC contributions with or without collaboration; (2) broader review of all Scopus-indexed journals with "radiology*" in the title (2001-2024), focusing on LMIC authorship; (3) comprehensive assessment of all Scopus-classified "Radiology, Nuclear Medicine and Imaging" publications (2021-2024), including output and citation data from 187 countries and various global regions.
Results: In Pediatric Radiology, only 3.4% of the 8,907 articles involved LMIC collaborations, and 0.9% were authored by LMIC researchers. The number of annual independent LMIC contributions never exceeded 5 until recently. In journals containing "radiology" in the title, LMIC researchers contributed 2.3% of all articles through collaboration and 1.25% independently, with 2024 data revealing continued reliance on partnerships (476 collaborative vs. 276 independent LMIC articles). The USA contributed 53,474 publications (26.67%) and received 362,681 citations (33.75%), whereas China produced 44,851 publications (22.37%) with 237,884 citations (22.14%). Africa produced 4,375 publications and received 22,161 citations, Latin America contributed 4,150 publications with 30,061 citations, and South America generated 3,590 publications with 26,084 citations. The Middle East had the highest citation-per-publication ratio (6.1), followed by the Asia Pacific (5.7), the Organization of Islamic Cooperation (5.3), South Asia (5.2), and Africa (5.1).
Conclusion: The data illustrate that LMICs remain underrepresented in radiology research. Targeted policy reforms, funding mechanisms, and capacity-building strategies are needed to enhance equity and support LMIC-driven radiology scholarship.
期刊介绍：
Official Journal of the European Society of Pediatric Radiology, the Society for Pediatric Radiology and the Asian and Oceanic Society for Pediatric Radiology
Pediatric Radiology informs its readers of new findings and progress in all areas of pediatric imaging and in related fields. This is achieved by a blend of original papers, complemented by reviews that set out the present state of knowledge in a particular area of the specialty or summarize specific topics in which discussion has led to clear conclusions. Advances in technology, methodology, apparatus and auxiliary equipment are presented, and modifications of standard techniques are described.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
