目的:探讨利用MSCT动态增强及MPR技术所观察的各种征象,对胸腺瘤与常见纵膈恶性肿瘤的鉴别价值。方法:回顾性分析125例经手术病理证实的纵膈恶性肿瘤及胸腺瘤的CT表现,全部病例均行平扫及增强扫描,采用多平面重组(MPR)技术,行横断面、冠状面、矢状面重建。结果:125例纵膈肿瘤中,胸腺瘤61例;纵膈性肺癌41例;恶性淋巴瘤20例;恶性生殖细胞瘤3例。结论:纵膈肿瘤虽分类众多,但利用MSCT动态增强及MPR技术能更清楚的显示病变及病变与临近组织脏器的关系,对肿瘤良恶性的定性具有重要意义,对肿瘤组织来源的分析也有引导作用。
Objective: To explore the use of dynamic enhancement of MSCT and MPR observed by various signs of thymoma and common differential diagnosis of mediastinal malignancies. Methods: CT findings of 125 cases of mediastinum malignant tumors and thymoma confirmed by surgery and pathology were retrospectively analyzed. All cases underwent plain scan and enhanced scan. The cross-sectional, coronal, Reconstruction. Results: Of the 125 mediastinal tumors, there were 61 cases of thymoma, 41 cases of mediastinal lung cancer, 20 cases of malignant lymphoma and 3 cases of malignant germ cell tumor. Conclusion: There are many types of mediastinal mediastinal tumors, but using MSCT dynamic enhancement and MPR technology can clearly show the relationship between lesions and lesions and adjacent tissues and organs, which is of great significance for the qualitative and quantitative analysis of benign and malignant tumors. Lead role.
