Combination of S-Detect and strain elastography in the conventional ultrasonic diagnosis of breast tumors

目的探讨S-Detect技术联合弹性成像辅助常规超声鉴别诊断乳腺肿瘤良恶性的价值。方法回顾性分析2018年4月至2020年1月在汕头大学医学院第一附属医院超声检查的136例乳腺肿块患者的超声诊断资料,对超声科诊断为乳腺影像学报告和数据系统3类及以上的乳腺病灶,依次采用常规超声、应变式弹性成像应变率比值法(strain ratio,SR)、S-Detect检查技术进行横断面研究,并获得相应的良恶性判断结果,比较分析各单独诊断及联合诊断的效能。结果常规超声、SR、S-Detect单独及常规超声+SR、常规超声+S-Detect、常规超声+S-Detect+SR联合诊断乳腺肿瘤等六种方法的受试者工作曲线下面积(area under the receiver operating characteristic curve,AUC)分别为0.776、0.839、0.802、0.861、0.832和0.870。SR、S-Detect、常规超声+SR、常规超声+S-Detect常规超声+SR+S-Detect与常规超声组间比较,差异具有统计学意义(Z值分别为1.49、0.70、2.76、2.52、2.96,P值分别为0.137、0.484、0.006、0.012、0.003)。其中以常规超声+S-Detect+SR联合方法的准确度最高,为84.1%;与病理结果比较,其Kappa值为0.687,一致性最强。结论S-Detect联合应变式弹性成像技术辅助常规超声能显著提高乳腺肿瘤良恶性的诊断效能。

Objective To explore the value of s-detect combined with elastography in the differential diagnosis of benign and malignant breast tumors.Methods The ultrasound diagnosis data of 136 patients with breast mass examined by ultrasound in the First Affiliated Hospital of Shantou University Medical College from April 2018 to January 2020 were retrospectively analyzed.The breast lesions diagnosed as BI-RADS 3 or above were analyzed by conventional ultrasound,strain elastic imaging strain ratio(SR)and S-Detect Computer-aided Diagnosis(CAD)technology successively and were used for cross-sectional study.The corresponding benign and malignant judgment results were obtained,and the efficacy of individual diagnosis and combined diagnosis were compared and analyzed.Results Conventional ultrasound,SR,S-Detect alone and conventional ultrasound+SR,conventional ultrasound+S-detect,conventional ultrasound+S-detect+SR combined diagnosis of breast tumors,the area under the receiver operating curve(AREA under the receiver operating curve Characteristic curve,AUC)were 0.776,0.839,0.802,0.861,0.832 and 0.870,respectively.SR,S-Detect,conventional ultrasound+SR,conventional ultrasound+S-detect and conventional ultrasound+SR+S-detect were compared with conventional ultrasound group,Z values were 1.49,0.70,2.76,2.52,2.96,respectively,and P values were 0.137,0.484,0.006,0.012 and 0.003,respectively.The difference was statistically significant.The accuracy of conventional ultrasound+S-Detect+SR was the highest(84.1%),compared with pathological results,its Kappa value was 0.687,showing the strongest consistency.Conclusion S-detect combined with strain elastography assisted by conventional ultrasound can significantly improve the diagnostic efficiency of benign and malignant breast tumors.
