OBJECTIVE. Our aim was to determine the use of advanced technology and archiving and the contribution of countries other than United States in the articles published in the American Journal of Roentgenology (AJR) and Radiology. We analyzed the association of these features with the type of research, the main technical features of the modalities used, and the countries of origin.

MATERIALS AND METHODS. We determined the proportion of articles published in 18 randomly selected issues of the AJR and Radiology that required advanced imaging techniques and relied on the analysis of archived data. "Advanced technology" was defined as imaging techniques that serve a purpose other than simple anatomic imaging or that are not widely available because of the high cost of the technology, such as functional imaging and computer programming designed for an individual study or simulation studies. We analyzed the association of these features with the country of origin, the topic, and the methodology used.

RESULTS. Sixteen percent of the studies required advanced technology. MR imaging, CT, and sonography were the most frequently used modalities (31%, 27%, and 15% of studies, respectively). Archiving was used in 37% of the studies, and 67% of the original articles were prospective. The articles most commonly originated in North America (67%), Europe (20%), and Asia (12%).

CONCLUSION. Only a small percentage of published research studies required advanced technology and approximately one third of the studies used archiving. These results may suggest that other criteria, such as the design of the study, its relevance for daily clinical use, and the originality of the paper, have a major impact on the acceptance of papers in clinically oriented radiology journals.
