Abstract: In order to explore the clinical value of percutaneous biopsy guided by ultrasound combined with CT for the diagnosis of peripheral lung cancer, the effects of CT, ultrasound and combined guided percutaneous biopsy in the patients were compared. The results showed that the accuracy of benign and malignant tumors percutaneous biopsy guided by CT combined with ultrasound was significantly higher than that of ultrasound or CT alone (P<0.05). In malignant tumors, the accuracy rate is 100% for squamous cell carcinoma, small cell lung cancer, poorly differentiated cancer, large cell carcinoma, adenosquamous carcinoma, metastatic cancer, and indefinite cancer; in benign lesions, lung abscess and tissue pneumonia, pulmonary aspergillosis, pneumonia, and granuloma were all 100% accurate. Compared with CT-guided puncture, the incidence of percutaneous pneumothorax under CT and ultrasound guidance was significantly reduced (P<0.05).Compared with ultrasound-guided puncture, the incidence of percutaneous pneumothorax and hemoptysis under CT and ultrasound guidance was significantly reduced (P<0.05). In conclusion, CT combined with ultrasound-guided percutaneous puncture is a sensitive tool for the diagnosis of peripheral lung cancer. It can accurately obtain materials and improve the diagnostic accuracy of patients.
