摘要
目的：通过分析和掌握MRI信号征象，提高诊断和鉴别诊断球后病变能力。材料和方法：69例球后病变，术前接受了MRI检查。常规SE序列，T1加权和T2加权的多回波成像。结果：根据其MRI信号征象，大致可分为四种信号表现。多数非肿瘤性病变的MRI信号征象，不同于一般肿瘤性病变的信号改变，具有一定特征性改变。结论：MRI可以根据病变部位以及MRI信号特征对眼眶病变做出正确的定性诊断，为临床提供重要诊断和治疗依据。
Purpose: In order to improve the ability of diagnosis and differential diagnosis of retro- ocular disorders, the MRI signals had been studied. Materials and Methods: 69 cases with retro-ocular disorder were studied with MRI. Results: According to MRI signal findings, the signal menifestations were classified into four types. The results indicated that there are special MRI signal findings in most of retro ocular disorders. Conclusion: MRI examination plays an important role in the diagnosis of retro-ocular disorders.
