目的 評價B超引導下核心針活檢術（CNB）對不可觸及的乳腺病變（NPBL）的診斷價值。方法 采用18G Tru-cut針結合活檢槍對88例患者的96個NPBL行B超引導下CNB，并與切除活檢病理結果比較。結果 NPBL大小4～23mm（平均13.1mm）。在CNB中，86個為良性，2個為可疑惡性，6個為惡性，2個取材不良。在切除活檢中9個為惡性，87個為良性。CNB可疑惡變的2個NPBL均為惡性，1個惡性NPBL誤診為乳腺腺病，取材不良的2個NPBL均為良性。本組NPBL中惡性病變占9.38%（9/96），B超引導下CNB對NPBL的良惡性診斷正確率為98.94%（93/94），診斷乳腺癌的敏感性為88.89%（8/9），特異性為100%（8/8），良性病變的病理診斷符合率為97.70%（85/87），取材不良為2.08%（2/96）。結論 B超引導下CNB對NPBL的診斷具有較高的敏感性和特異性，結果準確可靠。
