Grasso, E. Faiella, G. Luppi, E. Schena, F. Giurazza, R. Del Vescovo, F. D'Agostino, R. Cazzato, B. Beomonte Zobel] Purpose: Percutaneous lung biopsies (PLBs) performed for the evaluation of pulmonary masses require image guidance to avoid critical structures. A new CT navigation system (SIRIO, "Sistema robotizzato assistito per il puntamento intraoperatorio”) for PLBs was validated. Methods: The local Institutional Review Board approved this retrospective study. Image-guided PLBs in 197 patients were performed with a CT navigation system (SIRIO). The procedures were reviewed based on the number of CT scans, patients' radiation exposure and procedural time recorded. Comparison was performed with a group of 72 patients undergoing standard CT-guided PLBs. Sensitivity, specificity and overall diagnostic accuracy were assessed in both groups. Results: SIRIO-guided PLBs showed a significant reduction in procedure time, number of required CT scans and the radiation dose administered to patients ( $$p<0.001$$ ). In terms of diagnostic accuracy, SIRIO proved to be more accurate for small-sized lesions ( $$<$$ 20mm) than standard CT-guidance. Conclusion: SIRIO proved to be a reliable and effective tool when performing CT-guided PLBs and was especially useful for sampling small ( $$<$$ 20mm) lesions.
