N/A Objectives: Percutaneous needle biopsy in the most reliable invasive method of obtaining the confirm diagnosis of peripheral pulmonary nodule. Needle aspiration combinde with cytologic examination is being used with increasing frequency in the diagnosis of pulmonary nodules and masses. Percutaneous needle lung biopsy was done in pulmonary or mediastinal lesions using 19 Gauge fine aspiration needle or 14 Gauge cutting needle, and the results were compared with respect to diagnostic accuracy and complications. Methods: Over a periods of recent ten years. 476 patients who had localized pulmonary lesions and underwent percutaneous needle lung aspiration and biopsy using 19 Gauge fine aspiration needle or 14 Gauge cutting needle. Results: The age distribution of the patients was from sixteen to eighty-one years old. Among 467 patients, 337 patients were male and 130 patients were female. In 244 patients, sizes of the lesions were less than 4cm, in largest diameter, and in 223 patients, sizes of the lesions were larger than 4cm, but the size of the lesion was not correlated with malignancy. Diagnosic yields of the 14 Gauge cutting needle and the 19 Gauge fine needle were 88.3% and 78.3% respectively. Success rate of benigm and malignant lesion was more higher in 14 Gauge cutting needle than 19 Gauge fine aspiration needle. Common diseases were priamry lung cancer, tuberculoma, abscess in order of frequency. The complications of procedure were mild pneumothorax in ten patients, mild hemoptysis in six patients and subcutaneous emphysema in one patient. With Cutting needle and aspiration needle, complication rate was 2.73% and 2.36%, respectively. Conclusion: Percutaenous needle lung biopsy with cutting needle under the chest computed tomogram and biplane fluoroscopy had lower complication rate and high diagnostic success rate for the intrathoracic lesions
