【摘要】 目的 :探讨CT对原发性纵隔肿瘤的诊断价值。方法 :对 76例经临床病理证实的原发性纵隔肿瘤的CT表现进行回顾性分析。依据纵隔九分区划定肿瘤部位 ,结合密度测定判断肿瘤的性质来源。结果 :不同质地的纵隔肿瘤有其好发部位及特征CT表现 ,术前CT诊断准确率达 96 .0 5 % (73/ 76 )。结论 :CT对提高原发性纵隔肿瘤的术前诊断率 ,指导临床治疗是一种有效的检查方法 ,同时CT可鉴别引起纵隔增宽的非肿瘤性病变。更多还原

【Abstract】 Objective:To assess the values of CT in the diagnosis of primary mediastinal tumour(PMT). Methods:CT manifestations of 76 cases of PMT were retrospectively analysed,all cases were confirmde by surgery or biopsy. The site of PMT was depended on the nine areas of mediastinum.Results:Various PMT respectively have their common site and special CT signs. The accuracy of CT in diagnosis of PMT was 96.05%. Conclusions:CT is a more reliable imaging modality in improving the diagnostic rate of PMT,and CT can differ the cause of mediastinal widening whether tumours or non tumour lesions. [更多还原
