Efficacy of On-Site Specimen Adequacy Evaluation of Image-Guided Fine and Core Needle Biopsies

Abstract

On-site evaluations improved the percentage of definitive "positive" diagnoses of the malignant lesions on cytology from 33% (5/15) to 74% (53/72) (p = 0.003). On-site evaluation did not have any effect on the diagnostic yield of the lesions that were determined to be benign on followup (p = 0.54).
