Value of CT-Guidance Automatic Biopsy Needle in Interventional Diagnosis of Chest

目的 评价自动活检针在胸部介入性诊断中的应用价值。方法 应用Cook公司生产的Quick Core自动活检针在CT导向下对 69个胸部病变进行了活检。结果 69个病灶共进行了 12 6次穿刺 ,2 1G活检针穿刺取材成功率为 81%(5 6/69) ,18G活检针成功率为 10 0 %。良性病变 10个 ,恶性病变 5 9个。恶性病变中 5 7个病灶阳性 ,2个假阴性 ,敏感性97% (5 7/5 9) ,特异性 10 0 %。结论 自动活检针安全、高效、操作简便可常规应用于CT导向下胸部介入性诊断。

Objective To define the value of automatic biopsy needle in the interventional diagnosis of chest (IDC). Methods Sixty nine lesions were performed percutaneous biopsy on chest with automatic biopsy needle. Results One hundred and six biopsies were performed in the 69 lesions,the successful biopsy rate was 81%(56/69) with 21G needles and 100% with 18G needles.There were 10 benign lesions,and 59 malignant lesions among which 2 lesions were not diagnosed,the sensitivity of biopsy was 97%,and the specificity was 100%. Conclusion Automatic biopsy needle is a safe,effective and easy operated,which can be used in the conventional CT guided IDC.
