• •Outcomes of CT fluoroscopy-guided lung biopsy of nodules ≤ 8 mm were evaluated.•The biopsy resulted in high diagnostic accuracy of 95.7 %.•No severe complications were observed.•Lower lobe nodules and prone position were risk factors for diagnostic failure. To evaluate the diagnostic yield and safety of computed tomography (CT) fluoroscopy-guided cutting needle biopsy (CNB) for pulmonary nodules ≤ 8 mm. Data of CT fluoroscopy-guided CNB for pulmonary nodules ≤ 8 mm performed in a single institution were retrospectively analyzed. One hundred and seventeen biopsy procedures for 117 pulmonary nodules (mean size, 7.4 mm) in 114 patients were included in the study. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall diagnostic accuracy were calculated. Univariate analyses were performed to elucidate the risk factors for diagnostic failure (i.e., non-diagnostic, false-positive, or false-negative results). Complications were graded per the Clavien-Dindo Classification. One (0.9 %) non-diagnostic biopsy result was found. The diagnostic accuracy was 95.7 % (112/117). The sensitivity and specificity were 95.8 % (91/95) and 95.5 % (21/22), respectively. PPV and NPV were 98.9 % (91/92) and 87.5 % (21/24), respectively. Univariate analyses showed that nodules in the lower lobes (p = 0.006) and prone biopsy position (p = 0.021) were the significant risk factors for diagnostic failure. The incidence of pneumothorax requiring chest tube placement (Grade IIIa) was 6.8 % (8/117). No Grade IIIb or higher complications were observed. CT fluoroscopy-guided CNB for pulmonary nodules ≤ 8 mm showed a high diagnostic yield without severe complications.
