【摘要】 目的探讨早期类风湿性关节炎腕关节的X线与磁共振成像的诊断价值。方法分析20例早期类风湿性关节炎患者的腕关节X线片和MRI,SE序列T1WI和T2WI及T2WI抑脂像和增强MRI进行对比研究。结果X线平片示20例患者均有腕关节软组织肿胀,12例骨质稀疏,2例骨囊状破坏,2例关节间隙稍窄,4例骨质无异常改变;MRI示20例均可见不同程度范围的滑膜炎及韧带、肌腱损伤、血管翳,骨质侵蚀16例,骨髓水肿13例。结论MRI在提供病变炎性过程,如肌腱滑膜炎、关节积液、骨髓水肿、骨质侵蚀等的变化明显优于X线平片;对早期和活动期病变敏感性高。更多还原

【Abstract】 Objective To investigate the value of the MRI and plain radiography in the diagnosis of the wrists with early rheumatoid arthritis(RA).Methods 20 patients with early RA underwent radiography and MRI on both wrists.The SE T1WI,T2WI,fat suppression and FE T2WI Gd-DTPA enhanced scan were performed.Radiography and magnetic resonance imaging(MRI) of the wrists were compared.Results Among 20 patients,there were 12 cases with osteoporosis,2 cases with destructions of bone,2 cases with joint space narrowing and 4 cases without abnormity in the wrists radiography.All the 20 patients were with abnormity in the wrists MRI scan,including synovitis,tendon and ligament injury and pannus formation.There were 16 cases with bone erosion,13 cases with bone oedema.Conclusion MRI is superior to plain radiography to show the abnormities of wrists with early rheumatoid arthritis.It can demonstrate the synovitis,articular effusion,bone oedema and bone erosion.Its sensitivity to the early RA is very high.And enhanced MRI can also show the bone erosion and ligament attachment and bone marrow abnormally enhanced.更多还原
