THE INTERNATIONALIZATION OF THE AMERICAN JOURNAL OF ROENTGENOLOGY - 1980-1992

OBJECTIVE, The purpose of this study was to determine whether signific ant changes have occurred in the number of foreign articles published in the American Journal of Roentgenology since 1980. MATERIALS AND MET HODS, A total of 3398 articles published in AJR during two 3-year peri ods (1980-1982 and 1990-1992) were classified by type, subject, radiol ogic technique, organ system, and national origin. Additionally, 2865 manuscripts submitted to AJR from 1990 to 1992 were analyzed to determ ine the probability of manuscript acceptance based on country of origi n. RESULTS. From 1980 to 1982, 158 (10%) of 1610 articles published in AJR originated from institutions outside the United States. By 1990-1 992, international articles accounted for 441 (25%) of 1788 published papers (p < .00001). Although the total number of published articles f rom most nations increased during the decade, Korea, Japan, and German y made the largest advances. International contributions in the 1990s were most numerous in the following areas: adult radiology, abdominal/ gastrointestinal imaging, pulmonary/thoracic imaging, sonography, and interventional radiology. Notwithstanding these trends, manuscripts su bmitted from international sources are somewhat less likely to be acce pted for publication than those originating from the United States (ac ceptance rate for major papers 27% vs 33%, p = .01). CONCLUSION. The A merican Journal of Roentgenology is becoming increasingly internationa lized, with Korea, Japan, and Germany making particularly striking adv ances in the past decade.
