Abstract BACKGROUND: The purpose of this retrospective study was to compare the results and complication rate in CT guided percutaneous trans-thoracic fine needle aspiration biopsies (FNAB) and core biopsies of lung lesions, and to determine the applicability of these needles. PATIENTS AND METHODS: In 242 patients (166 males; 76 females) with mean age of 58.9 years (13-84 years) CT guided biopsies of lung lesions were performed on dual slice CT equipment. The average diameter of lung lesion was 2.9 cm (1.2-6.3 cm). For FNAB's 20 - 22 G Chiba needles and for core biopsies 14 G biopsy needles were used. The samples were sent for the histological analysis. The cytological or histological results and the eventual complications were compared. RESULTS: FNAB's cytological samples were adequate for definitive diagnosis in 117 patients (79.60 \%) and inadequate in 30 patients (20.40 \%). Core biopsies samples were adequate in 92 (96.85 \%) patients and non- representative (necrotic tissue) in 3 (3.15 \%). Pneumothorax as the most frequent complication was detected in 14 (9.7 \%) of the patients in the group of FNAB's and in 30 (31.5 \%) of the patients with the core biopsy group. CONCLUSIONS: The results showed that percutaneous transthoracic CT guided biopsies of lung lesions were an effective and safe procedure in the diagnosis of lung lesions. Core biopsy gives a higher percentage of representative samples than FNAB, and is a preferred method regardless of the higher rate of complications.
