Abstract
目的:探讨超声弹性成像(Ultrasound Elastography,UE)2种评分标准诊断乳腺占位性病变的价值。方法:对80例患者共93个乳腺占位性病变,先行常规二维超声检查,再行UE,分别以评分5分法和改良评分标准进行UE评分,评分≥4分诊断为乳腺恶性占位性病变,≤3分诊断为良性,以术后病理结果对照,分别计算2种标准诊断乳腺恶性占位性病变的敏感性、特异性、准确性。结果:评分5分法诊断乳腺恶性占位性病变的敏感性为84.4%,特异性为93.4%,准确性为90.3%;改良评分标准诊断乳腺恶性占位性病变的敏感性为90.6%,特异性为95.1%,准确性为93.5%。结论:UE改良评分标准对乳腺占位性病变的定性诊断更为实用、准确,优于评分5分法,具有临床推广价值。
