超声弹性成像联合声触诊组织成像量化技术在BI-RADS 4类乳腺肿块诊断价值的比较

摘 要 目的 探讨超声弹性成像联合声触诊组织成像量化技术（VTQ）对BI-RADS 4类乳腺肿块的诊断价值。方法 选取我院经病理确诊的乳腺肿块患者95例（共97个病灶），所有病例均先行二维超声诊断为BI-RADS 4类，再行弹性成像和VTQ检查，以病理结果为金标准，绘制二维超声、弹性成像联合VTQ检查诊断乳腺肿块的受试者工作特征曲线并比较其诊断效能；比较弹性成像联合VTQ技术与二维超声对乳腺肿块BI-RADS分类诊断结果的差异。结果 二维超声的诊断敏感性、特异性、准确率、阳性预测值、阴性预测值及AUC分别为87.8%、53.57%、41.38%、58.06%、85.71%及0.703，弹性成像联合VTQ技术调整后BI-RADS分类诊断的敏感性、特异性、准确率、阳性预测值、阴性预测值及AUC分别为95.12%、83.93%、79.05%、81.25%、95.92%及0.895，AUC比较差异有统计学意义（Z=2.26，P＜0.05）。结论 弹性成像联合VTQ技术可提高对BI-RADS 4类乳腺肿块的诊断价值。

Ultrasound elastography in combination with acoustic touch quantitative tissue imaging technique in the BI-RADS 4 classes breast lumps the comparison of diagnostic value

ABSTRACT Objective Explore ultrasound elastography in combination with acoustic touch tissue imaging quantification (VTQ) of BI - RADS 4 class to assess the diagnostic value of breast lumps.Method Select our hospital by pathological diagnosis of 95 patients with breast lumps (a total of 97 lesions), all cases were first two-dimensional ultrasonic diagnosis of BI - RADS 4 classes, elasticity imaging and VTQ check again, with the pathological results as the gold standard, draw two-dimensional ultrasound and joint elasticity imaging VTQ examination in the diagnosis of breast lumps and compare the diagnostic performance; the receiver-operating characteristic curve The difference between the combined VTQ technology and two-dimensional ultrasound in the classification of the breast lumps bi-rads was compared.Results Two-dimensional ultrasound diagnostic sensitivity, specificity, accuracy, positive predictive value, negative predictive value and AUC is respectively 87.8%, 53.57%, 41.38%, 58.06%, 85.71% and 0.703, the elasticity imaging joint VTQ adjusted BI - RADS classification diagnostic sensitivity, specificity, accuracy, positive predictive value, negative predictive value and AUC were 95.12%, 83.93%, 79.05%, 81.25%, 95.92% and 0.895, AUC comparative difference was statistically significant (Z = 2.26, P < 0.05).Conclusion Elastic imaging combined with VTQ technology can improve the diagnostic value of bi-rads 4 mammary masses.
