摘　　要：目的探讨MRI在系统性红斑狼疮并发症状性骨梗死诊断中的价值。方法回顾性分析近十年来我院就诊的19例SLE合并症状性骨梗死患者的临床资料和MRI图像。结果(1)19例均为多发,共97个病灶、累及77个骨骼,主要位于股骨远端和胫骨近端。(2)91个病灶呈“地图样”改变,6个病灶呈小灶性异常信号。(3)19个病灶边缘呈“单环征”,1个病灶边缘呈“双环征”,71个病灶边缘呈“三环征”。(4)19例均合并相应的关节积液,17例共23个关节面受累。结论SLE合并症状性骨梗死在MRI上呈多种形态、多种信号的骨质破坏,MRI能早期评估骨梗死的范围和程度,为临床诊疗方案的制定提供一定的帮助。Objective To investigate the value of MRI in the diagnosis of bone infarction with systemic lupus erythematosus(SLE).Methods Retrospective analysis of clinical data and MRI images of 19 SLE patients with symptomatic bone infarction who visited our hospital.Results(1)All 19 cases were multiple,A total of 97 lesions,involving 77 bones which located in distal femur and proximal tibia primarily.(2)91 lesions demonstrated map changes typically,6 lesions demonstrated long T1 and long T2,short T2 focally.(3)19 lesions demonstrated single-ring-sign,1 lesions demonstrated double-ring-sigh,71 lesions demonstrated three-ring-sign.(4)19 cases had joint effusion,and 17 cases with 23 articular surfaces involved.Conclusion The MRI findings of bone infarction with SLE are various forms and signals of bone destruction,MRI can early evaluate the scope and degree,providing certain assistance for the clinical diagnosis and treatment.
