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。
Objective: To investigate the diagnostic value of CT in primary mediastinal tumors. Methods: The CT findings of 76 cases of primary mediastinal tumors confirmed by clinical pathology were analyzed retrospectively. According to the nine segments of mediastinal delineation of the tumor site, combined density determination to determine the nature of the tumor. Results: The mediastinal tumors with different texture had its predilection sites and CT features. The accuracy of preoperative CT diagnosis was 96.5% (73/76). Conclusion :CT can improve the preoperative diagnosis rate of primary mediastinal tumors and guide clinical treatment as an effective method. CT can identify non-tumorous lesions that cause mediastinal widening.
