摘　　要：目的探讨纵膈CT对重症肌无力(MG)患者胸腺病变的诊断价值。方法对264例MG患者纵膈CT和胸腺病理检查结果进行对照分析。结果纵膈CT对MG患者胸腺病变诊断的准确度为61.36%。纵膈CT诊断正常胸腺、胸腺增生、胸腺瘤的敏感度分别为75%、36.73%、97.06%,特异度分别为72.62%、97.44%、81.48%。结论纵膈CT是诊断胸腺病变的较好方法,对胸腺瘤的诊断价值较高,但对胸腺增生的诊断具有一定的局限性。Objective To study the diagnose value of CT appearance of the thymus in patients with myasthenia gravis. Methods To correlate CT appearance of the thymus with results of histologic examination of thymic tissue in 264 patients with MG. Results Diagnose accuracy of thymus CT is 61.36. The sensitivity of CT in diagnose normal thymus,lymphoid hyperplasia and thymoma is 75,36.73 and 97.06,respectively. The specificity of CT in diagnose normal thymus,lymphoid hyperplasia and thymoma is 72.62,97.44,81.48. Conclusion CT is a good method to diagnose thymus pathology. CT has advance in distinguishing thymoma from other changes and is of limited value in distinguishing thymus hyperplasia from normal thymus or thymoma.
