Abstract :Objective: The aim of this study was to evaluated the effectiveness of  computed tomographyinsert ignore into journalissuearticles values(CT); guided transthorasic fine needle aspiration biopsy in the diagnosis of lung mass lesions. Material and Method: In this study, we are presenting 354 CT guided TTFNAB materials. The 348 of aspirations were performed from lung directly and 6 of them were performed from masses with mediastinal location. After the lesion was localized by CT, aspiration biopsy was performed by thoracic surgeon with 20-22 gauge Chiba needle by using 20 ml. Results : Among the 220 patients who underwent TTFNAB insert ignore into journalissuearticles values(354 aspiration biopsy);, 163insert ignore into journalissuearticles values(46.04%);  were diagnosed as tumor, 74insert ignore into journalissuearticles values(20.90%);  as suspicious lesion, 71insert ignore into journalissuearticles values(20.05);  as benign lesion and 46insert ignore into journalissuearticles values(12.99%);  as aspirate nondiagnostic. 140insert ignore into journalissuearticles values(39.54%); aspirata cell blocks were applied to 134 cases. Immunohistochemical and histochemical studies were performed in these cases and type differentiation could be made in tumor. Conclusion: TTFNAB-CB in expert hands and experienced pathologists is fairly accurate for lung masses  and can be regarded as an acceptable procedure for early  diagnose  and treatment  planning  purposes in most lung lesions.
