CT引导细针穿刺活检术诊断肺部病灶的应用与进展

摘要

肺内肿块的诊断及鉴别诊断在临床上十分常见.CT引导下肺穿刺(活检)术是目前诊断肺内肿块的主要方法之一.该方法主要通过CT扫描确定进针点及引导进针,抽出细胞组织行病理诊断,适用于周围型肺肿块及不能或不愿行纤维支气管镜检查的中央型肺肿块.此方法目前在临床上应用广泛,穿刺成功率、准确度及敏感度高,不良反应少.随着CT扫描技术的提高、立体定位技术的应用及病理学的发展,CT引导下肺穿刺(活检)术有望进一步推广应用.%The diagnosis and differential diagnosis of pulnonary tumor was very common problem in clinic. CT-guided percutaneous needle biopsy was one of the main methods in the diagnosis of pulnonary tumor. This method decide the needling spot and the process of needling by CT scan, and draw out the cell tissue for pathological diagnosis. This method refer to peripheral and central type lung tumor which can't or won't diagnose by bronchofibroscope. For the high achievement ratio, accuracy rating,sensitivity and rare adverse effect, this method was generally used. As the improving of CT scanning technique, the use of stereotaxis technique and the development of pathology, CT-guided percutaneous needle biopsy was expected to further extend.
