为了前瞻性研究肺癌所致的胸壁和纵隔浸润,采用人工气胸与 CT 相结合(气胸 CT)的方法进行评估。对象和方法 43例肺癌患者中,30例常规 CT 显示肿瘤接近胸壁,25例接近纵隔,但均无明确的肿瘤转移证据。常规 CT 检查层厚为1cm,所有患者均作增强扫描.气胸 CT 检查:于腋前线第5或第6肋间,胸腔穿刺注入300～500ml 空气,转动患者的体位,使肿块与可疑的转移灶之间产生气胸,以层厚1cm进行 CT 扫描。若肿块损伤肋骨或明显地扩展到胸壁
For the prospective study of lung cancer caused by chest wall and mediastinal infiltration, the use of artificial pneumothorax and CT (pneumothorax CT) method for evaluation. Subjects and Methods Of 43 patients with lung cancer, 30 cases of conventional CT showed that the tumor was close to the chest wall and 25 cases were close to the mediastinum. However, no clear evidence of tumor metastasis was found. Conventional CT examination of the thickness of 1cm, all patients were enhanced scan.Pneumothorax CT examination: in the axillary line 5th or 6th intercostal space, thoracentesis injection of 300 ~ 500ml air, rotating the patient’s position, the mass and suspicious metastases Between the production of pneumothorax to 1cm layer thickness CT scan. If the lumps damage the ribs or apparently expand to the chest wall
