Bibliometric analysis of the Spanish MR radiological production (2001-2007).

Objective: To evaluate the number and characteristics of papers on MR imaging written by radiologists in Spain and published in 2001-2007 Medline-indexed journals, including a comparison with the MR research output from German radiological departments.

Materials And Methods: Specific search profiles were devised to retrieve items from the Medline database. Relationship with the topic and major thematic areas of the articles, publication year, journal, language of publication, and mean impact factors were analyzed.

Cardiac MR imaging: balanced publication by radiologists and cardiologists.

Purpose: To retrospectively evaluate the number of articles on cardiac magnetic resonance (MR) imaging written by authors from radiology and cardiology departments and published in Medline-indexed journals from 1999 to 2004 and the relationship between the author's specialty and various parameters.

Materials And Methods: Specific search profiles were devised to retrieve items from the Medline database. Eight hundred seven articles were included in the study.

Scientific papers presented at the European Congress of Radiology: a two-year comparison.

The purpose of this report was to determine the rate at which abstracts orally presented at the European Congress of Radiology (ECR) 2001 were published in 2001-2005 Medline-indexed journals and to compare publication rates and factors with presentations at the ECR in two different periods (2001 and 2000). Absolute and relative publication rates (APR, RPR) and different publication-related factors were analysed. From 991 abstracts originating from 52 countries, 449 articles (APR 45%) were subsequently published in 125 journals, most frequently in European Radiology (n=79, 18%).

Publication of material presented at radiologic meetings: authors' country and international collaboration.

Purpose: To estimate the influence of the authors' country and collaboration on the probability of subsequent full publication of material from oral presentations at the 2000 European Congress of Radiology (ECR).

Materials And Methods: After searching the Medline database for articles published between 2000 and 2003, all articles that originated from presentations at the ECR in 2000 and were published in journals indexed in the Journal Citation Report were evaluated. Relative likelihood of full publication depending on the country in which an abstract originated was compared with that of Austria, which is the host country of the ECR.

Scientific papers presented at the European Congress of Radiology 2000: publication rates and characteristics during the period 2000-2004.

To determine the rate at which abstracts orally presented at the ECR 2000 were published between 2000-2004, and to identify predictive factors of publication and differences between abstracts and subsequently published papers. Specific search profiles were devised to retrieve items from the Medline database. From 1020 abstracts originating from 39 countries, 479 articles (publication rate 47%) were subsequently published in 139 Medline-indexed journals, most frequently in European Radiology (14%).

Hypothetical influence of non-indexed Spanish journals on the impact factor of radiological journals.

Objective: The aim of this study was to analyze the hypothetical changes in the 2001 impact factor of 52 radiological journals included in the Science Citation Index-Journal Citation Reports by also counting cites proceeding from 73 Spanish journals on different medical specialties. Also, to estimate the possible impact factor of the official Spanish radiology journal, Radiologia, not included in this database.

Materials And Methods: A modified 2001 impact factor of 52 radiological journals and Radiologia was obtained by adding the number of cites in 1999 and 2000 from the medical Spanish journals.
