Аннотация
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.
