【摘要】：目的比较剪切波弹性模量参数弹性最大值(Emax)、平均值(Emean)、最小值(Emin)、标准差(SD)和弹性比值(Eratio)在评价乳腺病灶良恶性中的价值,以确定最具诊断价值的参数。方法 302例经手术或穿刺活检确诊的乳腺病灶纳入研究,采用受试者工作特征曲线(ROC)确定Emax、Emean、Emin、SD、Eratio和超声乳腺影像报告及数据系统(BI-RADS)分类的诊断临界值,比较上述参数独立评价和分别联合超声BI-RADS分类评价乳腺病灶良恶性灵敏度、特异度和约登指数的差异。结果 Emax独立评价和联合超声BI-RADS分类评价乳腺病灶良恶性灵敏度、特异度和约登指数分别为0.87、0.97、0.84和0.86、0.97、0.83,均明显高于其他参数(P均0.01)。结论 Emax评价乳腺病灶的诊断效能优于其他参数,可作为评价病灶乳腺良恶性的重要参考指标。
[Abstract]:Objective to compare the value of the elastic modulus of elastic modulus (Emax), the mean value (Emean), the minimum value (Emin), the standard deviation (SD) and the elastic ratio (Eratio) in evaluating the benign and malignant breast lesions, in order to determine the most diagnostic value. Methods 302 cases of breast lesions diagnosed by surgery or biopsy were included in the study, and the subjects were employed. The characteristic curve (ROC) was used to determine the critical value of the diagnosis of Emax, Emean, Emin, SD, Eratio and ultrasonic breast imaging report and data system (BI-RADS). The above parameters were compared independently and combined with the ultrasonic BI-RADS classification to evaluate the differences of the sensitivity, specificity and index of the breast lesions. BI-RADS classification was used to evaluate the sensitivity of benign and malignant breast lesions. The specificity and the Jordan index were 0.87,0.97,0.84 and 0.86,0.97,0.83 respectively, which were significantly higher than those of other parameters (P 0.01). Conclusion Emax evaluation of breast lesions is superior to other parameters, which can be used as an important reference index for evaluating benign and malignant breast lesions.
