作为一种操作简便、损伤小的定性诊断方法，经皮肺穿刺术对周围性肺结节或肿块，具有纤维支气管镜、胸腔镜等无法比拟的优点，有较高的定性诊断价值。ＣＴ密度分辨率高，断层扫描没有骨骼重影，定位准确，能对透视下不能发现或不易到达的病变部位穿刺，对恶性肿瘤的诊断敏感性 As a simple, less invasive qualitative diagnostic method, percutaneous pulmonary puncture on the peripheral pulmonary nodules or lumps, with fiber bronchoscopy, thoracoscopy and other unmatched advantages, have a higher qualitative diagnostic value. CT density resolution, tomography without skeletal ghosting, accurate positioning, can not be found under fluoroscopy or difficult to reach the lesion puncture, the sensitivity of the diagnosis of malignant tumors
