目的探讨螺旋CT引导下可调式切割针对肺内球形病灶穿刺活检的临床应用价值。方法采用GE HiSpeed CT/i高档螺旋CT扫描机，扫描时间0.8～1.0 s，螺距1.0～1.5，层厚3～5 mm，利用机上自带活检程序（Biopsy），连续三层扫描。使用Magnum自动活检枪以18 G、20 G和21 G切割针，射程分别为15 mm和22 mm对52例肺内结节病灶行活检。结果螺旋CT引导下活检针在肺内滞留时间为10 s，自带活检程序使扫描准备时间为2 s。定性诊断率为96.15%（50/52例），并发症为21.15%。结论螺旋CT引导下可调式切割针能有效缩短活检针肺内滞留时间、提高定位准确度并减少并发症，适用于肺内球形病灶穿刺活检。

Objective　To evaluate spiral CT guided adjustable cut-needle biopsy of pulmonary nodules. 　Methods　GE HiSpeed CT/i spiral CT was used with scanning time 0.8～1.0s, pitch 1.0～1.5:1, slice thickness 3～5mm, auto- biopsy program of three slices. 52 cases with pulmonary nodules were performed by Magnum auto-biopsy gun with 18G, 20G and 21G needles, and shooting distance were 15 mm and 22 mm, respectively.　Results　The detaining time of biopsy needle in lung was 10s under the guided of spiral CT. Scanning preparing time was 2 s with auto-biopsy program. The determining diagnostic rate was 96.15%. Side effect was 21.15%.　Conclusion　Spiral CT guided adjustable cut-needle biopsy can effectively shorten the detaining time of biopsy needle in lung, raise locating accuracy and reduce the side effect. It is suit for pulmonary nodule biopsy.
