To determine the value of functional (flexion) magnetic resonance imaging (MRI) studies in patients with rheumatoid arthritis (RA) suspected of having cervical (C)-spine involvement.
Four patients with RA suspected of having C spine involvement, with neurological symptoms and/or signs, and who had normal MRI in neutral position, underwent functional MRI.
In all 4 patients functional MRI provided additional information. Cord compression (3 patients) and angulation of the cord (1 patient) were evident only in this view.
Functional MRI provided additional information in these patients and may be indicated in patients with RA suspected of having C spine involvement who have a normal MRI study in a neutral position.
确定功能（屈曲位）磁共振成像（MRI）检查对疑似颈椎受累的类风湿关节炎（RA）患者的价值。
4例疑似颈椎受累、有神经症状和/或体征且中立位MRI正常的RA患者接受了功能MRI检查。
4例患者的功能MRI均提供了额外信息。仅在该体位下可见脊髓受压（3例患者）和脊髓成角（1例患者）。
功能MRI为这些患者提供了额外信息，对于中立位MRI正常但疑似颈椎受累的RA患者可能具有应用价值。
