2. Core Biopsy of Breast and Axillary Lesions : Technical and Clinical Aspects
Abstract : The aims of this work were to image and analyze the needle behavior at automated core biopsy, to investigate the clinical utility of an alternative core biopsy technique using a semiautomated gun in breast and axillary lesions, and also to compare core biopsy with surgical specimens in malignant breast lesions regarding histologic features and hormone receptor expression.In two experimental studies, using butter and silicon phantoms, respectively, the needle pass was imaged and its dynamic behavior studied.

3. Comparison of stereotactic fine needle aspiration biopsy and core needle biopsy in breast lesions
Abstract : Purpose: The purpose of this study was to evaluate the diagnostic value of two biopsy methods by comparing stereotactic fine needle aspiration biopsy (S-FNAB) with stereotactic core needle biopsy (S-CNB). The biopsies were performed by the same radiologist, in the same breast lesion on the same occasion, in order to establish which method that best can be recommended in different kind of mammographically detected lesions.
