目的：探讨MRI、X线片、CT检查在儿童系统性红斑狼疮（juvenile systemic lupus erythematosus，JSLE）骨梗死中的诊断价值。
方法：自2015年1月至2017年1月，对行MRI、X线片、CT检查的11例SLE骨梗死儿童的影像学资料进行回顾性分析，其中男1例，女10例；年龄6~16岁，平均13岁。11例行MRI检查，9例行X线片检查，3例行CT检查，对其影像表现进行描述和分析。
结果：骨梗死共计累及60个部位，30个骨干-干骺端，8个髌骨，21个骨骺，1个距骨。11例MRI检查均检出病灶，典型表现是地图样改变，病灶边缘可呈长T1长T2信号，"双环征""三环征"。9例X线片检查中5例检出病灶；3例行CT检查中2例检出病灶；X线片及CT早期常无明显异常，慢性期表现为硬化边环绕低密度灶。
结论：MRI能显示早期骨梗死，X线及CT只能显示慢性期改变，MRI是诊断骨梗死的最有效方法。 |

Abstract:
Objective: To investigate diagnostic value of MRI,X ray and CT for bone infarction in children with systemic lupus erythematosus.
Methods: Eleven systemic lupus erythematosus children with bone infarction were retrospectively analyzed from January 2015 to January 2017,and tested by MRI,X-ray and CT. Among them,including 1 male and 10 females aged from 6 to 16 years old with an average of 13 years old. All patients were detected by MRI,9 patients were detected by X-ray and 3 patients were detected by CT,imaging findings were analyzed.
Results: The location of bone infarction involved 60 sits,30 sites located on metaphyseal-diaphyseal region,8 located on patella,21 located on epiphysis,and 1 located on talus. Focus of 11 patients were detected by MRI,the main manifestation showed geographic change,long T1 and T2 signal could seen around focus,and showed double ring sign and three ring sign; 5 of 9 patients by X-ray examination detected focus;2 of 3 patients by CT examination detected focus. No abnormity seen at early stage by X-ray and CT examination,and low density focus around harden edge at chronic stage.
Conclusion: MRI could display bone fracture at early stage,X-ray and CT could only display lesion at chronic stage,MRI is the most effective method in diagnosing bone infarction. |
