摘　　要：目的探讨MRI检查技术在减压性骨坏死早期诊断中的效果。方法选择2000～2016年在同济大学附属杨浦医院进行职业健康检查的52名接触高气压环境作业人员作为调查对象，进行劳动卫生学调查和职业健康检查，包括双肩、双髋、双膝关节x线检查、CT检查及MRI检查。评价MRI检查的效果。结果囊变作为减压性骨坏死重要的影像学特征，在MRI检查中表现为T1WI序列呈低或稍低信号和T2WI序列呈高信号，与x线检查和cT检查相比有较高的检出率，Kappa一致性检验发现MRI与x线检查及CT检查具有较高的一致性。同时MRI检查还可以发现骨髓腔坏死的早期病变。结论MRI检查是诊断早期减压性骨坏死的有效检查方法，可以提高减压性骨坏死的早期诊断率。Objective To investigate the value of MRI in the early diagnosis of diagnosis of dysbaric osteonecrosis. Methods Labor hygiene investigation and occupation health were examined on 52 high pressure operating personnel, were selected for the examination of both shoulders, hips and knees with X-ray and CT scan. Results The cystic sign in dysbaric osteonecrosis as an important imaging feature, which perform in the MRI examination for T1W I sequence showed low or slightly low signal and T2W I sequence showed high signal, and X-ray and CT have a lower detection rate than MRI. The Kappa consistency test showed a high consistency with the two methods. At the same time MRI examination also can discover the bone marrow cavity necrosis early pathological change. Conclusion MRI is an effective method for the diagnosis of early dysbaric osteonecrosis, which can improve the early diagnosis rate of dysbaric osteonecrosis.
