PURPOSE: This study explored the value of flat detector C-arm CT-guidance system
in performing percutaneous transthoracic needle biopsy (PTNB) for lung lesions in
clinical practice. METHODS: A total of 110 patients with solid lung lesions were
enrolled to undergo PTNB procedures. The mean diameter of lesions was 4.63 cm
(range, 0.6-15cm). The needle path was carefully planned and calculated on the
C-arm CT system, which acquired three-dimensional CT-like cross-sectional images.
The PTNB procedures were performed under needle guidance with fluoroscopic
feedbacks. RESULTS: Histopathologic tissue was successfully obtained from 108
patients with a puncture success rate of 98.2% (108/110). The diagnostic accuracy
rate was found to be 96.3% (104/108). There was only one case of pneumothorax
(0.9%) requiring therapy. The rates of mild pneumothorax and hemoptysis were low
(12.0% and 6.5%, respectively). In addition, procedural time could be limited
with this technique, which helped to reduce X-ray exposure. CONCLUSION: Our study
shows that C-arm CT-based needle guidance enables reliable and efficient needle
positioning and progression by providing real-time intraoperative guidance.
