  • Title: [Interest of magnetic resonance imaging in rheumatoid arthritis].
    Author: Theumann N, Berner IC, Dudler J.
    Journal: Rev Med Suisse; 2005 Mar 09; 1(10):670-3. PubMed ID: 15828369.
    Abstract:
    Magnetic Resonance Imaging (MRI) is the best imaging method in early detection and management of rheumatoid arthritis (RA). There are other imaging methods available as ultrasound, scintigraphy, computed tomography and plain radiography for imaging RA but MRI provides the best sensitivity in detecting inflammatory changes in the joints. MRI shows the best intra and interobserver reliability and low variation between repetitive examinations. MRI has shown the best visualisation and the greater sensitivity to detect erosion in early RA, compared to standard radiography. The use of a contrast agent further increases the sensitivity in detecting erosions and differentiate synovial proliferation from fluid collections. Otherwise, intraossous cyst, tenosynovitis, bone marrow edema, that are concomitant manifestations of the disease, are best imaged by MRI. MRI assists in the early detection of rheumatoid arthritis, which allows earlier initiation of treatment.
