[Abstract] Objective: To evaluate the value of PCNB (percutaneous needle biopsy) CT-guided lung lesions diagnosis. Methods: The hospital in March 2017 ~ lung space occupying lesions row in June 2019 admitted to the study, all patients are in line PCNB CT-guided preoperative diagnosis, drawn a record of success, the success rate of the final drawn, diagnosis typing accuracy and diagnostic accuracy, the rate of complications occur. Results: The 40 patients disposable diagnostic coverage success rate was 87.5% (35 patients), the final drawn 100% success rate (40), 36 cases of diagnosis, diagnostic accuracy was 90.00%, wherein the subject malignant lesions the rate of 88.24% (containing 80.00% of lung squamous cell carcinoma, 5 cases of lung adenocarcinoma 100%, 6 cases of colorectal cancer 85.71%, 90.91% small cell lung carcinoma, large cell undifferentiated carcinoma 80.33%), the detection rate of benign lesions 100.00% (100.00% containing abscess, tuberculoma 100.00%, 100.00% pneumoconiosis), the adverse reactions was 12.50% (containing 5.00% pneumothorax, needle tract bleeding 2.50%, 2.50% pulmonary compressed air thrombosis 2.50%). Conclusion: CT guided PCNB with a diagnosis of non-occupying lesions can significantly improve the success rate of the drawn diagnostic accuracy, while effectively reduce the incidence of complications.
