Abstract：Objective:To assess the clinical application of computed tomography(CT)-guided percutaneous core needle biopsy(CNB) for small( ≤ 1 cm) pulmonary lesions.Method:A retrospective study was undertaken comprising 78 patients who underwent CT-guided CNB for small pulmonary lesions.To assess the accuracy of the procedure,the diagnosis at biopsy was compared with the surgical,pathological and clinical follow-up.Result:The overall diagnostic accuracy was 92.3%.The sensitivity for malignancy and specificity for benign lesions were 88.5%and 100%,respectively.Positive and negative predictive values were 100%and 81.3%,respectively.Fifteen patients(19.2%) had pneumothorax after CT percutaneous CNB of the lung.The significant risk factors affecting the incidence of pneumothorax were lesion-pleural distance(P=0.004) and needle-pleural angle(P=0.012).Bleeding occurred in 14 patients(17.9%).The only significant risk factor affecting the incidence of bleeding was lesion-pleural distance(P=0.019).Conclusion:CT-guided percutaneous CNB of small pulmonary lesions provides high diagnostic accuracy with acceptable complications.
