Abstract:

BACKGROUND: Rheumatoid arthritis diagnosis often depends on the clinical manifestations, laboratory tests and imaging examination. Magnetic resonance imaging technology has a good tissue resolution, and has higher sensitivity in the early diagnosis of rheumatoid arthritis.
OBJECTIVE: To compare and analyze the domestic and foreign research of magnetic resonance imaging in the diagnosis of rheumatoid arthritis and to understand the trend of the research in this area.
METHODS: A computer-based search was performed in CNKI database and SCI database from January 2002 to December 2011 for the articles related to the magnetic resonance imaging in the diagnosis of rheumatoid arthritis. The key words were “rheumatoid arthritis, image, magnetic resonance imaging” in Chinese and “MRI, rheumatoid arthritis, RA” in English. The analysis capabilities of the database and Excel charts function were used to analyze the data characteristics.
RESULTS AND CONCLUSION: A total of 60 articles were obtained from CNKI database and 300 articles were obtained from SCI database, the number of the articles obtained from the SCI database was significantly higher than that obtained from CNKI database, the number of the articles from two databases showed an overall upward trend. For the articles related to the rheumatoid arthritis diagnosed by magnetic resonance imaging, most of them published in CNKI database were Magnetic Resonance Imaging, Medical Imaging Technology and Chinese Computed Imaging and most of the articles in SCI database were Annals of the Rheumatic Diseases, and the highest impact factor was 8.727. For the articles contained in CNKI database, 5 articles were published by People’s Hospital of Peking University, and in SCI database, 37 articles were published by University of Leeds, followed by Auckland University and the Hospital of University of Copenhagen. For the download frequency, Arthritis and Rheumatism got the highest reference times, so Arthritis and Rheumatism has become the classic journal of rheumatoid arthritis diagnosed by magnetic resonance imaging. To analyze from the national distribution of the articles, most of the articles in SCI database were published by England and United States, and a small amount of articles from China were published in SCI database.
