Needle localization and fine-needle aspiration biopsy of nonpalpable breast lesions with use of standard and stereotactic equipment.

摘要: Recent development of mammographic stereotactic localization devices has created considerable interest in the possibility fine-needle aspiration biopsy (FNAB) non-palpable breast lesions. The results FNAB performed during course 50 lesion localizations were evaluated. authors compared two methods localization, one using a standard unit and technique other technique. similar regardless With all inadequate specimens considered benign, sensitivity, specificity, diagnostic accuracy for 71%, 100%, 93%, respectively, technique, 80%, 95%. Although these are preliminary number cases is small, findings suggest that needle placement with may be as accurate
