摘　　要：本文对３５例经手术和病理证实的纵隔肿瘤进行二维超声多普勒（２Ｄ－Ｄ）及磁共振（ＭＲＩ）诊断分析。结果表明，２Ｄ－Ｄ能在短时间内迅速全面地对纵隔肿瘤进行扫查，明确分辨出实质性和囊性肿物，同时多普勒能很好的将无回声的囊肿及血管区别开。由于胸廓及肺气的影响，个别患者超声不能显示肿瘤的全貌，其诊断符合率为９４％。ＭＲＩ可显示纵隔肿瘤的全貌，其诊断符合率为１００％，但该项检查费用较贵。Thirty-five cases of mediastinal tumor proved by operation and pathologic examination were studied with two-dimensional ultrasound Doppler (2D-D) and magnetic resonance imaging (MRI) The result indicated that mediastinal tumor can be easily scanned in the short time with 2D-D, which acouratly distinguished solid and cyst tumor, and it can greatly differentiate the cyst and vessel of the anechoic Because of the presence of thoracic and pulmonary air, the tumor can not be revealed as a whole in some individual patients The diagnostic accuracy of 2D-D was 94% MRI can demonstrate the whole body of the tumor with the diagnostic accuracy of 100% However, some patients can not accept MRI examination as it is relatively expensive
