Pulmonary nodules are small in size and easy to move with breathing. CT guided puncture is highly dependent on the personal experience of physicians, that is, the accuracy, efficiency and incidence of complications of puncture vary greatly among physicians. Puncture template (PT) assisted CT guided needle biopsy of pulmonary nodules has good clinical feasibility, which is expected to make up for the deficiency of simple CT guided needle biopsy, and make the needle biopsy of pulmonary nodules more accurate and standardized. This study intends to carry out a randomized controlled study to further evaluate the safety and effectiveness of PT assisted CT guided needle biopsy of pulmonary nodules, and provide higher quality data reference for its clinical application. Patients were randomly divided into two groups: PT assisted CT guided or simple CT guided lung biopsy. The operation related information, complications and postoperative pathological results of the two groups were collected. Primary end point: puncture accuracy Secondary end point: success rate of first needle puncture; complication rate (such as pneumothorax, bleeding, etc.); operation time; CT scan times; pathologic findings.
