CT引导下胸部穿刺已由1976年Haaga等首先应用来经皮肺穿刺活检扩展到肺脓肿引流,气胸引流,肺部肿瘤的放射性密封籽源植入等。有些胸部病变仅仅依靠影像学资料或纤维支气管镜,痰找肿瘤细胞等检查很难作出明确诊断。有些肺脓肿,脓胸对内科治疗疗效欠佳,故采用CT皮肺穿刺活检抽吸? CT-guided thoracentesis has been first applied by Haaga et al. In 1976 to percutaneous lung biopsy to extend lung abscess drainage, pneumothorax drainage, radioactive seed implantation of lung tumors, and the like. Some chest lesions rely solely on imaging data or fiberoptic bronchoscopy, sputum looking for tumor cells and other tests is difficult to make a clear diagnosis. Some lung abscess, empyema curative effect of medical treatment is poor, so the use of CT skin lung biopsy suction?
