  title = {Missed breast cancers at US-guided core needle biopsy: how to reduce them.},
  abstract = {<p>Ultrasonographically (US) guided core needle biopsy is currently recognized as a reliable alternative to surgical biopsy for the histopathologic diagnosis of breast lesions. However, despite advances in biopsy devices and techniques, false-negative diagnoses are unavoidable and may delay the diagnosis and treatment of breast cancer. The most common reasons for false-negative diagnosis are (a) technical or sampling errors, (b) failure to recognize or act on radiologic-histologic discordance, and (c) lack of imaging follow-up after a benign biopsy result. Technical difficulties (eg, poor lesion or needle visualization, deeply located lesions, dense fibrotic tissue) cause inaccurate sampling but can be reduced by using modified standard techniques. Radiologic-histologic correlation is also of critical importance in US-guided core needle biopsy. Radiologic-histologic discordance occurs when the histologic results do not provide a sufficient explanation for the imaging features and indicates that the lesion may not have been sampled adequately, so that repeat biopsy is warranted. Appropriate follow-up imaging is invaluable; even patients with concordant benign findings after US-guided core needle biopsy are directed to undergo follow-up imaging because there may be delays in the recognition of false-negative findings. Optimization of technique, radiologic-histologic correlation, and postbiopsy follow-up protocols are recommended to reduce the occurrence of false-negative diagnosis at US-guided core needle biopsy performed by radiologists.</p>},
