本文通过B超对44例纵隔肿瘤患者检查，重点讨论了纵隔肿瘤B超影像学特点及诊断中的意义。同时还讨论了纵隔肿瘤探查的部位及操作手法，强调在检查前应仔细阅读胸片和胸部CT片以便找出最佳探查部位和范围。B超在纵隔肿瘤检查的优点在于能直接探查肿瘤内部结构鉴别实质性和囊性肿瘤，探查肿瘤与周围脏器和血管的关系，在B超引导下经皮纵隔肿瘤穿刺活俭更为准确和安全。
In this article, 44 cases of mediastinal tumors were examined by B-mode ultrasonography, and the B-mode ultrasonographic characteristics and diagnosis of mediastinal tumors were discussed. At the same time, the location and operation methods of mediastinal tumor exploration were also discussed. It was emphasized that chest and chest CT scans should be carefully read before the examination in order to find out the best probe location and scope. The advantage of B-mode ultrasound in mediastinal tumor examination is that it can directly probe the internal structure of tumors to distinguish between substantive and cystic tumors, and probe the relationship between tumors and surrounding organs and blood vessels. Under the guidance of B-ultrasound, percutaneous epidermal tumors can be more accurate and Safety.
