Purpose: To determine the characteristics of the original articles on breast imaging published in Radiology between 2010 and 2012.
Materials and Methods: All 91 original articles (24 in 2010, 39 in 2011, and 28 in 2012) published in breast imaging section of Radiology between 2010 January and 2012 December were evaluated. The following information was abstracted from each article: content category, radiologic technique used, type of research, sample size, study design, number of authors, and country of the first author.
Results: The most common category of study was diagnosis (n = 30), followed by screening (n = 22), treatment monitoring (n = 8), intervention (n = 8), breast density (n = 7), computer-aided diagnosis (n = 7), biology (n = 5), radiation dose (n = 2), and contrast agents (n = 2). A total of 37 (41%) original articles used magnetic resonance (MR) imaging, followed by mammography (n = 23), ultrasonography (n = 11), digital tomosynthesis (n = 9), optical imaging (n = 3), fusion imaging (n = 3), nuclear medicine (n = 3), CT (n = 1), and synchrotron radiation mammography (n = 1). Sample size of research articles were less than 50 (n = 14), 51-100 (n = 15), 101-200 (n = 20), 201-500 (n = 14), 501-1000 (n = 11), and over 1000 (n = 17). Study design was prospective in 40 (44%), and retrospective in 51 (56%). Twenty-five (28%) were multicenter study. Five had one to three authors, 42 had four to seven, 40 had eight to 15, and four had over 16. The United States published 58% (53 of 91) of the articles, followed by England (n = 5), South Korea (n = 5), China (n = 5), Germany (n = 3), Italy (n = 3), Canada (n = 3), Netherland (n = 3), Japan (n = 3), France (n = 2), Austria (n = 2), Taiwan (n = 1), Norway (n = 1), Sweden (n = 1), and Spain (n = 1).
Conclusion: The bibliometric analysis of the breast imaging articles published in Radiology between 2010 and 2012 revealed characteristics of the current breast imaging research (diagnosis, screening, and treatment monitoring with MRI or breast density) that may provide useful information to researchers. The United States published over half of the articles, followed by England, South Korea, and China.
