ReviewMagnetic resonance imaging in early detection of rheumatoid arthritis.
Magnetic resonance imaging (MRI) is the modality of choice in early diagnosis and management of rheumatoid arthritis (RA). The pathologic processes in RA involve synovitis, joint effusion, proliferation of fibrovascular connective tissue, and the formation of pannus. Other imaging techniques available for imaging of RA include ultrasound, scintigraphy, computed tomography, and plain radiography (PR). ⋯ Other manifestations of RA such as intraosseous cysts, tenosynovitis, bone marrow edema, and carpal tunnel syndrome can also be visualized on magnetic resonance images. Advances in MRI include contrast-enhancement, dynamic, and quantitative techniques. MRI assists in the early detection of RA, which allows earlier initiation of treatment with disease-modifying therapies.
