PN was defined as a spherical/oval image of non-transparent lesions ≤ 3 cm in diameter with neighboring pulmonary parenchyma/non-linked to atelectasis, mediastinal lymphadenopathy, or pleural effusion [Resection was used to make the final diagnoses for both malignant and benign PNs. biopsy-based malignancy and specific benignity could be accepted as the final diagnosis [True-positive was postulated when biopsy-based malignancy/suspicious was confirmed as malignant at finalized-diagnosis. The true-negative was postulated when biopsy-based benignities confirmed benignities at finalized-diagnosis.Diagnosis yield = (biopsy-based malignancy + biopsy-based specific benignity)/all cases. Diagnostic accuracy = (true positive + true negative)/all cases with the final diagnosis. Pneumothorax and lung hemorrhage were assessed by chest CT. Lung hemorrhage was considered as a novel consolidating/ground-glass opacity around the needle tract [
