The diagnostic value of CT-guided needle aspiration biopsy (CT · NAB) was examined in 70 patients with intrathoracic tumor-like lesions (9 with mediastinal tumor-like lesions, 52 with intrapulmonary tumor-like lesions, 9 with pleural lesions). In 68 out of 70 cases (97%), the needle penetrated the lesion. The overall accuracy was 96% (67 out of 70 cases). The true positive rate was 93% (39 out of 42 cases) and the true negative rate was 90% (28 out of 31). Complications developed in 16 cases (23%). CT · NAB method was especially suitable in 22 out of 70 cases and their lesions were classified into 9 patterns by roentgenogram. Finally, we concluded that CT · NAB is a safe, easy and very efficient technique for diagnosing thoracic malignant lesions.
