The State of Radiology Research in Ethiopia: A Scoping Review

Radiology is an essential component of modern medicine and a rapidly evolving research field. The nature and dynamic of radiology research in Ethiopia remained largely unexplored This bibliometric scoping review was done to explore the current state of radiology research in Ethiopia.

Literature search was conducted using PubMed, Scopus, Embase, Web of Science, and Google Scholar from inception to June 15, 2024. Study screening, review, and selection were performed using EndNote Reference Manager. The key indicators assessed include publication trends, research themes, publication utility, contribution and collaboration of individuals and institutions, and journal metrics. Statistical analysis was done using R and VOS viewer software.

Though low in volume, radiology research publication is increasing in Ethiopia, with 241 publications from 1968 to 2024, accounting for 0.03% of the global radiology research output. Top contributing institutions were Addis Ababa University, Jimma University, and St. Paul's Hospital Millennium Medical College. The studies were largely focused on case-reports, cross-sectional studies, and diagnostic imaging. Systematic reviews, meta-analyses, artificial intelligence and trials constituted only 3% of the studies. Most publications (96.7%) were done by academic institutions. Most frequently used journals were Ethiopian Medical Journal and Ethiopian Journal of Health Sciences, accounting for 29% and 15% of the total publications, respectively. Publications in Q1 journals was 12%. International collaboration was 7%, with the USA being the primary collaborator.

To elevate the quality and impact of radiology research in Ethiopia, it is crucial to adopt contemporary and robust research methodologies, align research topics with global trends and technological advancements, and foster enhanced collaboration and productivity within the research community.
