ObjectivesTo evaluate gender differences in the authorship of articles published in two major European radiology journals, European Radiology (EurRad) and CardioVascular and Interventional Radiology (CVIR).MethodsA retrospective bibliometric analysis was performed of 2632 papers published in EurRad and CVIR sampled over a period of 14 years (2002-2016). The authors' gender was determined. The analysis was focused on first and last authors. In addition, the characteristics of the articles (type, origin, radiological subspecialty, and country) were noted.ResultsOverall, 23% of first authors and 10% of the last authors were women. The proportion of women significantly increased over time in EurRad from 22% in 2002 to 35% in 2016 for first authors (p > 0.001), and from 13% in 2002 to 18% in 2016 for last authors (p = 0.05). There was no significant increase in the proportion of female authors in CVIR over time. Female authors were more frequently identified in breast imaging (48%), pediatrics, and gynecological imaging (29%). There were more female authors in articles from Spain (34%), the Netherlands (28%), France, Italy, and South Korea (26%). Forty-one percent and 21% of women were first authors with a woman or man as last author, respectively (p < 0.001).ConclusionThere was a significant increase in female authorship in original diagnostic but not interventional imaging research articles between 2002 and 2016, with a strong influence of the radiological subspecialty. Women were significantly more frequently first authors when the last author was a woman.Key Points• There was a significant increase in female authorship in original diagnostic but not interventional imaging research articles between 2002 and 2016. • There is a strong influence of the radiological subspecialty on the percentage of female authors. • Women are significantly more frequently first authors when the last author is a woman.
