One hundred and thirty patients with pulmonary mass were studied under ultrasonography guided aspiration biopsy by four types of needle. The cytological positive cases were 57.1% in fine needle (22G), 79.6% in large needle (18G), 90.9% in canaliculated needle (18G) and 80.9% in cutting needle (14G), and the pathological positive cases were 0, 64.4%, 86.3% and 92.8% respectively. These data showed that the positive rate of fine needle puncture was the lowest one. Based on the pathological finding, canaliculated and cutting needle seem to be better than large one and it is the best choice to perform the pulmonary aspiration biopsy.
130例肺部肿块患者在超声引导下采用4种针进行穿刺活检。细针（22G）的细胞学阳性率为57.1%，粗针（18G）为79.6%，槽沟针（18G）为90.9%，切割针（14G）为80.9%，病理阳性率分别为0、64.4%、86.3%和92.8%。这些数据表明细针穿刺的阳性率最低。基于病理结果，槽沟针和切割针似乎优于粗针，进行肺部穿刺活检时槽沟针和切割针是最佳选择。
