摘要
目的：通过分析病变ＭＲＩ征象，并与ＣＴ比较，加深对眼部病变ＭＲＩ和ＣＴ的认识。材料和方法：５３例的ＭＲＩ和ＣＴ，其中４３例手术证实，其余临床随访证实。结果：ＭＲＩ诊断符合率为８８．７９％，ＣＴ７７．２％，常见的眼眶病变如血管瘤、炎性假瘤、泪腺混合瘤等都具有一定信号特征。结论：本文着重讨论了眼眶病变的ＭＲＩ表现，认为可以根据病变部位以及ＭＲＩ信号特征对大多数的眼眶病变做出准确诊断，ＭＲＩ的定性能力是肯定的。
Purpose: To understand deeply signs of MRI and CT of orbital disorder and improve diagnosis. Materials and Methods: 53 patients with orbital disorder proved by operation or typical clinical symptoms were examined with MRI and CT before treatment. Results: The diagnosis of 86.79% MRI and 77.27% CT are correct. There are some special MRI signal features in most of common orbital disorder such as hemangioma, peudotumor, lacrimal gland tumor and Meningioma etc. Conclusion: MRI is a very useful method to examine patients with orbital disorder and determine the nature of most of common orbital disorder.
