Estudio bibliométrico de la actividad, estructura y evolución de la radiología en España

From a bibliometric perspective, we reviewed: 1) the scientific activity in the field of diagnostic imaging in Spain, based on the percentage of presentations at the SERAM congresses (1994-1998) later published as articles in scientific journals. The value obtained (15%) is low in comparison with other international congresses, although similar to values for other national congresses in radiology. Both in national and international congresses, collaboration among radiologists from different institutions or countries and between radiologists and clinicians increases the percentage of publications, thus confirming the positive correlation between collaboration and scientific productivity. 2) We also examined the relationship between scientific productivity and the hierarchical structure of Spanish radiology departments (resident, associate, section chief, and department chief). Hierarchical roupings with the participation of residents were found to be more stable from year to year in scientific production, and the group residents + associates had the highest percentage of authorship (21%). 3) Finally, we reviewed the literature to assess the visibility and dissemination of the Journal Radiologia, estimating the impact factor that the journal would obtain if it were included in the Journal Citation Reports (JRC) database. We emphasize the importance of the inclusion of Radiologia both in Medline. the best known and most widely used source of information in the health sciences, and in the JCR.
