than 10 percent of the cases. With increasing practice our yield in the diagnosis of localized lung disease is now well over 90 percent. This is a safe simple procedure which can be accomplished in any hospital where image-intensification fluoroscopy and good cytologic services are available. In summary, we feel that the preferred method for obtaining tissue from undiagnosed localized lung lesions is fluoroscopically controlled needle aspiration biopsy. In diffuse lung disease a limited thoracotomy with open lung biopsy is used. We no longer perform cutting needle biopsies.
