摘要：目的  分析乳腺肿瘤的超声特点，探讨乳腺超声用于肿瘤良恶性分类诊断的意义。方法  选取2018年8月～2019年8月在我院治疗的行超声检查的乳腺肿瘤患者72例为研究对象，比较乳腺超声与手术病理肿瘤良恶性诊断率、良恶性肿瘤血流指标[血流阻力指数（RI）、收缩期峰值血流速度（PSV）]、血流信号分级及超声图像（形态规则、内部回声均匀、无钙化、肿块衰减）分布情况。结果  乳腺超声良、恶性肿瘤诊断结果与手术病理检查结果比较，差异无统计学意义（P>0.05）;恶性肿瘤RI、PSV均大于良性腫瘤，差异有统计学意义（P<0.05）;良性肿瘤血流信号0级、1级发生率高于恶性肿瘤，2级、3级发生率低于恶性肿瘤，差异有统计学意义（P<0.05）;恶性肿瘤超声诊断分布形态规则、内部回声均匀、无钙化、肿块衰减分布率与良性肿瘤比较，差异有统计学意义（P<0.05）。结论  超声在乳腺肿瘤良恶性诊断中诊断率高，尤其是对肿瘤区域定位、血流信号分级、超声征象分布情况显示较好，值得临床应用。

Abstract：Objective  To analyze the ultrasound characteristics of breast tumors and explore the significance of breast ultrasound in the diagnosis of benign and malignant tumors.Methods  72 patients with breast tumors who underwent ultrasound examination in our hospital from August 2018 to August 2019 were selected as the research subjects.[Resistance index （RI）， peak systolic blood flow velocity （PSV）]， blood flow signal grading and ultrasound image （regular shape， uniform internal echo， no calcification， mass attenuation）. ResultsThere was no statistically significant difference between the diagnosis results of benign and malignant tumors of breast and the results of surgical pathological examination（P>0.05）; RI and PSV of malignant tumors were greater than benign tumors， the difference was statistically significant （P<0.05）; blood of benign tumors the incidence of flow signal grades 0 and 1 is higher than that of malignant tumors， and the incidence of grades 2 and 3 is lower than that of malignant tumors， the difference was statistically significant （P<0.05）;Compared with benign tumors， the distribution of malignant tumors in ultrasound diagnosis has regular distribution patterns， uniform internal echo， no calcification， and tumor attenuation （P<0.05）.Conclusion  Ultrasound has a high diagnosis rate in the diagnosis of benign and malignant breast tumors， especially for the localization of tumor areas， blood flow signal classification， and the distribution of ultrasound signs， which are worthy of clinical application.

乳腺肿瘤（breast tumor）早期诊断是提高乳腺癌患者生存率，降低死亡率的决定因素[1]，但早期依据患者的临床症状、体征鉴别乳腺肿瘤的良恶性的难度较大[2]。乳腺超声是乳腺肿瘤检测的主要影像手段之一，通过对其图像处理，可为临床医生提供辅助诊断信息，该技术无辐射性，能够对患者的肿瘤情况进行全面观察。目前临床关于乳腺超声对肿瘤良恶性分类诊断标准尚存在争议，本研究结合2018年8月～2019年8月期间在我院治疗的72例乳腺肿瘤患者临床资料，探讨乳腺超声检查对肿瘤良恶性分类的诊断价值，以期为乳腺肿瘤诊治提供参考，现报道如下。
