Fine‐needle biopsy: Comparison of cellular yield with and without aspiration

Abstract

Fine-needle biopsies with and without aspiration were performed on 103 lesions, and the cellular yields obtained by the two techniques were compared. A scoring system was devised by which the amount of material obtained in each needle stick was estimated. The mean score/stick for fine-needle biopsy with aspiration was 2.7; for biopsy without aspiration, it was 2.9. The results of this study indicate that there is no significant difference in the amount of cellular material obtained by the two techniques. It is concluded that needle biopsy without aspiration may be performed routinely with good results.
