摘要： 〗［摘要］
目的  探讨S-Detect技术与弹性成像技术联合应用对乳腺影像学报告及数据系统4（Breast Imaging Reporting and Data System 4，BI-RADS4）类结节良恶性评估的诊断价值。
方法  采用二维超声、弹性成像技术及S-Detect技术对110例女性患者诊断为BI-RADS4类120个乳腺结节病灶进行良恶性鉴别，以术后病理诊断结果作为金标准，对比分析二维超声单独联合弹性成像技术，以及同时联合采用S-Detect技术与弹性成像技术的诊断效能。
结果  二维超声单独联合弹性成像技术诊断的敏感度为73.68%，特异度为82.92%，准确度为80.00%；而同时联合采用S-Detect技术与弹性成像技术诊断的敏感度为86.84%，特异度为87.80%，准确度为86.66%。二维超声单独联合弹性成像技术、同时联合采用S-Detect技术与弹性成像技术诊断乳腺BI-RADS 4类结节病灶良恶性的ROC曲线下面积分别为0.746和0.942（P＜0.05）。二维超声同时联合采用S-Detect技术与弹性成像技术诊断效能优于单独联合弹性成像技术（P＜0.05）。
结论   S-Detect技术联合弹性成像技术可作为一种新型的乳腺二维超声补充诊断手段，辅助二维超声诊断可明显提高对BI-RADS 4类乳腺结节的良恶性鉴别诊断的效能。

Abstract: ［Abstract］ Objective〖HTSS〗To explore the value of combined application of S-Detect and elastography in the diagnosis of benign and malignant breast Breast Imaging Reporting and Data System 4（BI-RADS4） nodules.
Methods〖HTSS〗Two-dimensional ultrasound, elastic imaging and S-Detect were used to distinguish the benign and malignant lesions of 120 breast nodules in BI-RADS4 class in 110 female patients. The results of postoperative pathological diagnosis were used as the gold standard. The diagnostic efficiency of two-dimensional ultrasound alone combined with elastic imaging and the combination of S-Detect and elastic imaging were compared and analyzed.
Results〖HTSS〗The sensitivity, specificity and accuracy of two-dimensional ultrasound combined with elastography were 73.68%, 82.92% and 80.00%, respectively. At the same time, the sensitivity, specificity and accuracy of S-Detect and elastography were 86.84%, 87.80% and 86.66%, respectively. The area under of ROC curve of two-dimensional ultrasound combined with elastic imaging and S-Detect combined with elastic imaging in the diagnosis of benign and malignant breast BI-RADS4 nodules were 0.746 and 0.942, respectively. The diagnostic efficiency of two-dimensional ultrasound combined with S-Detect and elastic imaging was better than that of elastic imaging alone(P＜0.05).
Conclusion〖HTSS〗S-Detect combined with elastography can be used as a new supplementary diagnostic method of two-dimensional ultrasound in the diagnosis of breast nodules. The assistant two-dimensional ultrasound diagnosis can significantly improve the effectiveness of differential diagnosis of benign and malignant breast nodules in BI-RADS4.
