【摘要】:目的探讨乳腺弹性成像中对照组织的大小对弹性应变率比值及诊断准确性的影响。方法选择病灶组织位置、大小不变的情况下,按对照组织大小分为4组,对照组织≥病灶组织(A组);病灶组织对照组织≥1/2病灶组织(B组);1/2病灶组织对照组织≥1/4病灶组织(C组);对照组织1/4病灶组织(D组)。对114例患者共139个乳腺病灶进行4组弹性应变率比值的测定,以病理诊断为基础,观察4组对照组织的大小对弹性应变率比值及良恶性病灶鉴别诊断的效能。结果 4组对照组织的大小对弹性应变率比值差异无统计学意义(P0.05)。4组诊断乳腺恶性病变的敏感性、特异性、准确性均较为接近,A、B、C、D组ROC曲线下面积分别为0.935、0.932、0.923、0.905,4组ROC曲线的两两比较,差异无统计学意义(P0.05)。以3.08为界点,A组漏诊3例,误诊5例;B组漏诊4例,误诊5例;C组漏诊5例,误诊6例;D组漏诊5例,误诊9例。结论以病理诊断为金标准,对照组织的大小对弹性应变率比值及诊断结果无明显影响。
