Abstract:
We performed a bibliometric search to evaluate number and scientific
"weight" of papers written by European radiologists, as compared with
colleagues from other countries, to measure the contribution of European
researchers to radiology journals, and to correlate bibliometric parameters
with some socio-economic factors of the different European nations. We
considered all peer-reviewed articles published by radiologists in
biomedical journals quoted by ISI over the 1995-2000 period.
To identify authors as radiologists, the string "radiol" had to appear in
the address of the corresponding author, and his country was considered as
the country of origin of the paper. The definition of Europe included the 15
countries of the European Union, plus Norway and Switzerland. The scientific
"weight" of the paper was assumed to be the impact factor of the journal of
the publication in that given year. Then, we considered the annual indexes
number of papers/population and number of papers/Gross Domestic Product
(GDP) in each country. Data were retrieved from the Eurostat annual
statistic reviews. From these bases, we obtained a comparison of the
scientific production among European radiologists, those from the U.S. and
those from the rest of the world. European radiological research is
responsible of almost 40% of the world scientific production in our field,
and Germany, UK and France are the leading publishers in Europe. An increase
of the number of papers written by European radiologists was noted in the
1995-2000 period, whereas the production from the U.S. had a slight
decrease. The mean concentration indexes papers/inhabitants and papers/GDP
were significantly lower in Europe than in the U.S., even if some small
European countries had higher values than the U.S. As a mean, European
research received a lower impact factor than that from the U.S. The
assessment of research output has progressively developed as an important
issue for the scientific research community. Although not flawless, and
often criticized for a variety of reasons, citation analysis is a
commonly used technique in this field, is a frequent means to "weight" the
scientific production of researchers and is one of the criteria used to
assign research grants.

Our study shows that European radiology is growing and its production is
increasing over time, thus indicating strong commitment to research from
European radiologists; however, European radiological research has not yet
reached leadership in the literature, and mean indexes addressing the level
of resources allocated to research are lower in Europe than in the U.S. This
latter point has notable exceptions, but indicates inadequacy of funding, at
least in some nations, and in Europe as a whole. The development of research
programs within the framework of the European Union specifically aimed to
radiology could lead to further advancement of our discipline.
