Abstract:
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. Data were obtained by
consulting the 2001 edition of the Journal Citation Reports in the "Web of
Science" database.

Results: The 16,985 bibliographical references were analysed (232 of them
to radiological journals). The journal with the largest increase in its
2001 impact factor (from 1.83 to 1.90) was Radiologic Clinics of North
America. European Journal of Radiology was the European journal with the hi-
hest increase (from 1.084 to 1.110) in the difference between the 2001
modified and original impact factor. The modified 2001 impact factor of the
34 American journals was statistically higher (P = 0.016) than that of the
18 European journals (1.64 versus 0.93). Differences between the 2001
modified and original impact factor were slightly higher in the American
journals (no statistically significant difference). The 2001 impact factor
of Radiologia was 0.056.

Discussion: Differences between the 2001 original and modified impact
factor were small, but larger in the American journals. The 2001 impact
factor of Radiologia was modest, although similar to other publications
included in the Journal Citation Reports. (c) 2004 Elsevier Ireland Ltd.
