Only 10% to 20% of nonpalpable breast lesions are malignant, yet all suspicious lesions must undergo biopsy. For many women with breast abnormalities, needle biopsy is a less expensive, quicker and better tolerated alternative to surgical excisional biopsy. Localization techniques that may be used during needle biopsy include clinical guidance, the grid coordinate system, ultrasound guidance and stereotactic guidance. Of these four options, only stereotactic guidance permits localization of a lesion in three dimensions. This article explains the principles behind stereotactic localization and discusses the equipment and personnel involved in the stereotactic breast biopsy procedure. It also discusses patient positioning techniques and sampling technique during stereotactic breast biopsy, with particular emphasis on the mammographer's role throughout the procedure.
不可触及的乳腺病变中只有10%至20%是恶性的，但所有可疑病变都必须进行活检。对于许多有乳腺异常的女性来说，针吸活检是一种比手术切除活检成本更低、速度更快且耐受性更好的替代方法。针吸活检过程中可使用的定位技术包括临床引导、网格坐标系、超声引导和立体定向引导。在这四种选择中，只有立体定向引导能够在三维空间中对病变进行定位。本文解释了立体定向定位背后的原理，并讨论了立体定向乳腺活检程序中涉及的设备和人员。还讨论了立体定向乳腺活检过程中的患者定位技术和取样技术，特别强调了乳腺造影技师在整个过程中的作用。
