摘　　要：目的:探讨MSCT、MRI联合诊断胸腺瘤的价值。材料和方法:回顾性分析36例经手术及病理证实的胸腺瘤的MSCT和20例MRI表现。结果:36例中,MSCT诊断侵袭性胸腺瘤9例,MRI诊断侵袭性胸腺瘤13例(13/20),手术病理证实侵袭性胸腺瘤17例。结论:CT是检出和诊断胸腺瘤的较佳方法之一,如怀疑侵袭性胸腺瘤,MRI检查能更准确地观察肿瘤边缘的改变与邻近组织间的关系,较明显地提高诊断准确率。Purpose： To analyze the MSCT and MRI features of thymomas and research their eompyehensive diagnosis value for thymomas. Matirals and Methods： 36 cases with thymoma proved by operation were analysed all patients were examined by MSCT and among them 20 cases were examined by MRI. Results： Among all 36 eases, 9 were diagnosed as invasive thymoma, and 13 eases among the 20 ea- ses by MRI were diagnosed as invaslve thymoma, and 17 eases of invasive thymoma were proved by operations and pathology. Conclusion： CT is the best way to check and diagnose thymoma, but the father examination on suspected invasive thymoma by MRI could improve the ac- curacy of diagnosis.
