摘要
目的探讨CT检查对纵隔肿瘤及肿瘤样病变的诊断价值,分析CT误诊的原因。方法回顾性分析经手术证实的纵隔占位性病变42例,全部病例均行CT检查,其中11例进行了增强扫描。结果不同质地的纵隔肿瘤及肿瘤样病变有其好发部位及特征性CT表现,术前CT诊断准确率达71.4%(30/42)。结论CT检查是提高纵隔肿瘤及肿瘤样病变的术前诊断率、指导临床治疗的一种有效方法。
Objective To investigate the efficacy of CT on diagnosis of mediastinal neoplasms and tu- morlike lesion to analyze the causes of misdiagnosis. Methods Forty two patients were examined with CT, 11 patients received contrast CT scan. All cases were confirmed by pathology. Results Various mediastinal neoplasms and tumor-like lesions with heterogeneous density have their own special demonstration on CT image and frequently occurred sites. The accuracy of diagnosis before surgery is 71.4 %（30/42）.
