[Magnetic resonance imaging. Density equalizing mapping analysis of global research architecture]

Area of Science:

• Medical Imaging
• Bibliometrics
• Radiology

Background:

• Limited scientometric analysis exists for magnetic resonance imaging (MRI) despite its medical significance.
• The evolving importance of MRI in healthcare systems lacks comprehensive evaluation.

Purpose of the Study:

• To conduct a scientometric analysis of MRI research publications from 1981 to 2007.
• To evaluate publication trends, international contributions, and citation impact of MRI research.

Main Methods:

• Utilized scientometric methods analyzing data from ISI Web of Science (1981-2007).
• Examined publication counts, geographical distribution, citation rates, and collaborations.
• Employed analytical techniques including density equalizing map projections.

Main Results:

• The USA dominated MRI publications (32.5%), followed by Germany (10.3%) and the UK (9.3%) in Europe.
• Western industrialized nations led MRI scientific development.
• Key research areas included radiology and neuroscience, with top journals being Neurology, Magnetic Resonance in Medicine, and Circulation.

Conclusions:

• Scientific interest and publication output in MRI show a continuous increasing trend.
• The findings reflect ongoing advancements and the expanding role of MRI in medical research.
