The application of spiral CT guided needle biopsy in pulmonary nodules
Abstract：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.
