The role of ultrasonographic guided transthoracic needle biopsy in diagnosis of peripheral lung mass

Transthoracic needle biopsy is a well established method for obtaining pathologic diagnosis in the lung mass that performed after a previous negative bronocoscopy. The goal of this study is evaluation of the safety and accuracy of ultrasonographic guided transthoracic needle biopsy for diagnosing peripheral lung mass. In a descriptive and prospective study from September 2005, 30 patients with peripheral lung mass with greater than 3cm in diameter and less than 5cm distance through the chest wall, underwent ultrasonographic guided transthoracic needle biopsy and it’s diagnostic accuracy and complications were analyzed
