摘要
目的 评估MRI对手腕部早期类风湿性关节炎的诊断价值。方法 对 3 0例临床诊断为早期类风湿性关节炎的患者进行手腕部X线平片和MRI检查 ,比较 2种技术对病变的显示能力。结果 X线平片显示所有患者均未见骨侵蚀 ,17例可见关节肿胀 ,2 8例可见骨质疏松 ,10例关节间隙轻度狭窄。MRI显示 2 0例关节面骨侵蚀 ,所有 3 0例均可见关节滑膜增厚、关节积液以及关节周围炎性渗出 ,2 3例可见血管翳形成 ,7例合并关节周围肌腱韧带损伤。平片和MRI对病变关节数目的检出率分别为 2 0 %及 81%。
Objective To assess the diagnostic value of magnetic resonance imaging (MRI) for early stage rheumatoid arthritis (RA). Methods X-ray plain films and MR exams of the wrist were performed in 30 patients with clinically diagnosed early RA. The ability of these two techniques to reveal the changes of RA was compared. Results On plain films, joint swelling was seen in 17 cases, periarticular osteoporosis in 28, narrowing of the joint space in 10 patients, but none of these patients showed bone erosions. With MRI, bone erosions were observed in 20 patients, polyarticular synovial hyperplasia, joint effusion, and periarticular inflammation tissue was seen in all 30 patients, pannus was showed in 23 patients. Abnormalities of tendons and ligaments were also diagnosed in 7 patients on MRI. Detecting rates of plain film and MR for abnormal joint numbers were 20% and 81%, respectively. Conclusion MR is a relatively better diagnostic tool for early RA.
