Comparative Study
Ultrasound versus MRI in the evaluation of juvenile idiopathic arthritis of the knee.
To examine the role of ultrasound versus magnetic resonance imaging (MRI) in assessing joint inflammation in patients with juvenile idiopathic arthritis (JIA) of the knee. ⋯ Ultrasound is a simple, inexpensive and valuable tool in evaluating the initial stages of JIA. In more advanced stages of JIA and also for monitoring the progression of the disease process and response to therapy, MRI examination following gadolinium proved to be superior in evaluation of the joint affection.
