运用弹性剪切波技术联合超微血流成像鉴别乳腺边缘毛刺肿块的良恶性价值

The Value of Elastic Shear Wave Technique Combined with Ultramicro-Flow Imaging in Differentiating the Benign and Malignant Edge of Breast Burr Mass

目的:探讨弹性剪切波技术联合超微血流成像在鉴别诊断乳腺边缘毛刺肿块的良恶性中的应用价值。方法:选取2020年6月~2022年12月乳腺边缘毛刺肿块患者125例。所有患者均接受弹性剪切波技术检查,并采用超微血流成像技术对病灶内血管及血流参数进行观察,与术后病理结果进行比较,分析二者在鉴别诊断乳腺边缘毛刺肿块的良恶性中的应用价值。结果:良性组弹性最小值、弹性最大值、弹性平均值、杨氏模量值(AveR)、肿块杨氏模量值(AveT1)、比值(Ratiol)等参数均低于恶性组(P<0.05);两组BI-RADS-US分级比较差异有统计学意义(P<0.05),且超微血管成像模式下良恶性病变血流Adler分级差异有统计学意义(P<0.05),良恶性病变均以3级为主;弹性剪切波技术联合超微血流成像诊断的灵敏度与特异度、准确度均明显高于单纯微血管成像、弹性成像(P<0.05)。结论:弹性剪切波技术联合超微血流成像的诊断效能较高,能较客观定性评价乳腺边缘毛刺肿物,为准确鉴别诊断乳腺边缘毛刺肿块的良恶性质提供帮助。

Objective:To evaluate the value of elastic shear wave technique combined with ultramicroflow imaging in the differential diagnosis of benign and malignant breast marginal burr masses.Methods:A total of 125 patients with breast marginal burr mass were selected from June 2020 to December 2022.All the patients were examined by elastic shear wave technology,and the blood vessels and blood flow parameters in the lesion were observed by ultramicro-flow imaging technology,and the application value of both in the differential diagnosis of benign and malignant breast marginal burr masses was compared with the postoperative pathological results.Results:The minimum elastic value,maximum elastic value,average elastic value,AveR,AveT1 and Ratiol parameters in benign group were lower than those in malignant group(P<0.05).There was statistically significant difference in BI-RADS-US grading between the two groups(P<0.05),and there was statistically significant difference in blood flow Adler grading between the benign and malignant lesions in SMI mode(P<0.05),and the benign and malignant lesions were mainly grade 3.The sensitivity,specificity and accuracy of the diagnosis of elastic shear wave combined with ultramicroflow imaging were significantly higher than that of simple microvascular imaging and elastic imaging(P<0.05).Conclusion:Elastic shear wave technique combined with ultramicro-flow imaging has high diagnostic efficiency,which can objectively and qualitatively evaluate the breast marginal burr masses,and provide help for accurately differentiating the good and evil properties of breast marginal burr masses.
