Computed tomography in guiding of fine needle aspiration biopsy of the lung and mediastinum.

Computed tomography displays the image of the chest in a transverse plane; therefore localization and depth calculation of the lung and mediastinal lesions to be biopsied can be done easily and in a precise manner. Use of computed tomography for guiding the biopsy procedure itself ascertains control of the needle tip inside the lesion and assures a positive result of the biopsy. The procedure of using computed tomography for the planning and guiding of fine needle aspiration biopsy in lung and mediastinal masses is described. The results in 105 patients examined are discussed and the value of the method is assessed.
