摘　　要：目的探讨二维超声、多普勒超声及超声弹性成像(UE)对乳腺肿块良恶性的鉴别诊断价值。方法分别采用二维超声、CDFI、脉冲多普勒血流显像(PDU)及UE检查100例患者共125个乳腺病灶,并与病理结果进行比较。结果病理为良性者40例共65个病灶,恶性者60例共60个病灶,二维超声诊断乳腺恶性肿瘤的敏感度为80.00%(48/60),特异度为78.46%(51/65),准确率为79.20%(99/125);CDFI诊断乳腺恶性肿瘤的敏感度为78.33%(47/60),特异度为83.08%(54/65),准确率为80.80%(101/125);PDU诊断乳腺恶性肿瘤的敏感度为71.67%(43/60),特异度为58.46%(38/65),准确率为64.80%(81/125);UE诊断恶性病变的敏感度为88.33%(53/60),特异度为75.38%(49/65),准确率为81.60%(102/125)。4种检查方法比较,诊断结果差异有统计学意义(χ2=13.155,P<0.05)。结论 UE鉴别诊断乳腺良恶性肿块的准确率高于二维超声和多普勒超声。Objective To investigate the value of two-dimensional ultrasound,Doppler ultrasonography and ultrasonic elastography（UE） in differentiating breast malignancy and benignancy.Methods One hundred patients with 125 lesions were examined with two-dimensional ultrasound,CDFI,pulsed Doppler ultrasonography（PDU） and UE,taking pathologic findings as the reference standard.Results Forty patients with 65 lesions were in the benign group and 60 patients with 60 lesions were in the malignant group.The sensibility,specificity,accuracy of two-dimensional ultrasound for differentiation was 80.00%（48/60）,78.46%（51/65） and 79.20%（99/125）,of CDFI for differentiation was 78.33%（47/60）,83.08%（54/65） and 80.80%（101/125）,while of PDU for differentiation was 71.67%（43/60）,58.46%（38/65） and 64.80%（81/125）,respectively.The sensibility,specificity,accuracy of UE for differentiation was 88.33%（53/60）,75.38%（49/65） and 81.60%（102/125）,respectively.There was significant difference in diagnosis results among the 4 methods（χ2=13.155,P〈0.05）.Conclusion The accuracy of UE in the differentiation of most breast tumors is higher than two-dimensional ultrasound and Doppler ultrasonography.
