title: Transthoracic needle aspiration biopsy--optimizing the yield.
abstract: Transthoracic needle aspiration biopsy (TNAB) is the procedure of choice for the diagnosis of focal pulmonary processes. TNAB can identify the entire spectrum of focal benign or malignant disease. Technique-dependent factors and the underlying pathologic processes that affect the diagnostic yield of TNAB are reviewed.
