Intérêt de l'imagerie par résonance magnétique dans le diagnostic précoce et l'évaluation de la polyarthrite rhumatoïde

Magnetic resonance imaging is commonly requested to establish an early diagnosis of rheumatoid arthritis. The sensitivity of MRI in detecting bone erosions and synovitis is greater than the other X ray methods. Early diagnosis of rheumatoid arthritis is helpful to optimize treatment; furthermore MRI gives a precise evaluation of the disease by quantifying the level of the synovitis. As a result MRI is becoming an important technique for determining the prognosis of this kind of disease.
