Clinical Application of CT-guided Percutaneous Needle Biopsy of Small Pulmonary Nodules

Objective:To evaluate the clinical value of CT-guided percutaneous needle biopsy of small pulmonary nodules(D≤1.5cm).Methods:65 patients with small pulmonary nodule underwent CT-guided percutaneous needle biopsy.The sensitivity,specificity,accuracy of diagnosis and complications were analyzed.Results:The sensitivity and positive prediction value for the diagnosis of malignant lesions were 92.3%(36/39) and 100% respectively.The specificity and negative prediction value for the diagnosis of benign lesions were 100% and 89.7%(26/29) respectively.Totally the accuracy of diagnosis was 92.3%(60/65).The incidence of complicated pneumothorax and pulmonary hemorrhage were 7.7%(5/65) and 10.8%(7/65) respectively.No specific treatment was undertaken after the biopsy procedure.Conclusion:CT-guided percutaneous needle biopsy for the diagnosis of small pulmonary small nodules(D≤1.5cm) showed high accuracy and low incidence of complication.
