目的 研究磁共振(MR)成像在诊断早期类风湿性关节炎(RA)中的作用。 材料和方法 20 名经临床和放射学证明患有 RA 的患者(3 名男性,17 名女性;年龄范围,21-72 岁)接受了评估,以确定诊断 RA 所致滑膜炎症的 MR 成像标准。 27 名疑似早期 RA 但无影像学异常的患者(16 名患有 RA,11 名无 RA [对照患者];3 名男性,24 名女性;年龄范围,19-75 岁)接受了评估,以测试使用该标准诊断 RA 的准确性。获得每位患者双手的冠状、脂肪抑制和钆对比材料增强的 T1 加权图像。 结果 MR 成像标准是手腕或双手掌指和/或近端指间关节的关节周围造影剂增强。在早期RA的诊断中,敏感性和阴性预测值均为100%,特异性为73%,准确性为89%。 结论 磁共振成像对于诊断早期 RA 非常有用。
PURPOSE To investigate the role of magnetic resonance (MR) imaging in diagnosing early rheumatoid arthritis (RA). MATERIALS AND METHODS Twenty patients (three men, 17 women; age range, 21-72 years) with clinically and radiologically proved RA underwent evaluation to define an MR imaging criterion for diagnosing synovial inflammation due to RA. Twenty-seven patients (16 with RA, 11 without RA [control patients]; three men, 24 women; age range, 19-75 years) suspected to have early RA but without radiographic abnormalities underwent evaluation to test the accuracy of using the criterion to diagnose RA. In each patient, coronal, fat-suppressed, and gadolinium contrast material-enhanced, T1-weighted images of both hands were obtained. RESULTS The MR imaging criterion was periarticular contrast material enhancement of the wrists or the metacarpophalangeal and/or proximal interphalangeal joints in both hands. In the diagnosis of early RA, sensitivity and negative predictive value were both 100%, specificity was 73%, and accuracy was 89%. CONCLUSION MR imaging is extremely useful in diagnosing early RA.
