Diagnostic sensitivity of bronchoalveolar lavage versus lung fine needle aspirate.
Abstract
Bronchoalveolar lavage (BAL) and lung fine-needle aspirate (LFNA) are commonly performed as the first line of investigation for a myriad of pulmonary problems associated with abnormal imaging findings (mass, cavitary lesion, infiltrates, etc.). The relative sensitivities of these two procedures are not well established for cytologic diagnosis of lesions for any single disease event. Records were searched for single pulmonary disease events with closely timed BAL and LFNA, as defined by both procedures occurring within
