Purpose: 1) To review the advantages of lung imaging-guided interventional procedures. 2) To present our experience with CT-guided procedures, practical difficulties, spectrum of findings and complications you may encounter during FNA/Biopsy.  

INTRODUCTION: The procedure is indicated for indeterminate pulmonary lesions. In lung cancer, when feasible, we should have tumour assessed for the presence of a driver mutation in order to offer a personalized targeted therapy (ALK, EGFR, KRAS) METHOD: All lung lesions punctured with CT-guidance at our institution since January 2012 are reviewed, with 130 lesions so far. DIAGNOSTIC ACCURACY: Most procedures have been diagnostic with non-small cell lung cancer being the most common diagnosis followed by metastasis. COMPLICATIONS AND DIFFICULTIES: Pneumothorax is the most common complication, usually small and not requiring chest tube. Hemoptysis is the second more common complication, rarely severe. CONCLUSION: Percutaneous needle biopsy of the lung has high sensitivity, specificity and is relatively safe, and should be considered an important diagnostic tool in the evaluation of pulmonary lesions. We can obtain reliable samples for mutational analysis. Careful case and technique selection is necessary to increase diagnostic yield and avoid unnecessary complications.
