摘　　要：目的探讨超声弹性成像在乳腺良恶性病灶鉴别诊断中的价值。方法应用常规超声、超声弹性成像对经手术病理证实的94例乳腺肿瘤患者,共计110个乳腺病灶进行超声检查,其中良性50个,恶性60个。结果常规超声诊断乳腺肿瘤的敏感性80.0%,特异性78.0%,准确性79.0%,阳性预测值81.4%,阴性预测值76.5%;超声弹性成像诊断肿瘤敏感性83.3%,特异性94.0%,准确性88.2%,阳性预测值94.3%,阴性预测值82.5%。超声弹性成像对乳腺肿瘤诊断的真实性和可靠性均较常规超声诊断高,差异有统计学意义(χ2=14.716,P=0.001)。结论超声弹性成像在乳腺病灶定性诊断上较常规超声有一定优势。Objective To explore the value of convention ultrasonography （CUS） and ultrasonic elastography （UE） in the differential diagnosis of breast lesions. Methods One hundred and ten lesions in 94 patients with breast tumor confirmed by pathology were examined by CUS and UE. Results The sensibility, specificity,accuracy positive predictive value （PPV） and negative predictive value （NPV） of CUS were 80.0%, 78.0%, 79.0%, 81.4% and 76.5%, respectively. For UE, they were 83.3%, 94.0%, 88.2%,94.3% and 82.5%, respectively. UE was superior to CUS in the differential diagnosis of breast tumors（X^2=14.716, P=0.001 ）.Conclusion UE is superior to CUS in the diagnosis of breast tumors.
