INTRODUCTION: Percutaneous core-needle biopsy is widely accepted for preoperative histologic assessment of suspicious @entity1558 . The purpose of this study was to asses the impact of continuous sonographic guidance on diagnostic accuracy of large core needle biopsy of palpable @entity1558 . METHOD: We analysed 170 @entity1558 in a retrospective study. Percutaneous breast biopsies were performed by using a biopsy gun with 14-gauge needles. Eighty-eight biopsies were performed under continuous ultrasound guidance (group II) and 82 biopsies without ultrasound documentation of the procedure (group I). Core needle diagnoses were compared with the @entity1 final tissue diagnosis as based on surgical excisional biopsy. RESULTS: In @entity1 group I, 17 lesions were categorized as @entity0 misses (sensitivity 79 %). The sensitivity in this group showed an obvious dependency on @entity5 size. Among the 17 @entity75 , 13 lesions were 3 cm in mean diameter or smaller. Two false negative findings occurred in group II (sensitivity 98 %), with a @entity5 size of 0.5 and 1.0 cm. CONCLUSION: Sonographic guidance is indispensable to ensure adequate diagnostic accuracy for core-needle biopsy of palpable @entity1558 .
