摘　　要：目的:探究乳腺影像报告和数据系统(BI-RADS)4类乳腺微小结节应用超微血流成像(SMI)技术良恶性鉴别诊断价值。方法:选取2023年5月至2023年10月在深河人民医院收治的患者60例,这些患者术前均经彩色多普勒超声诊断为BI-RADS 4类乳腺微小结节,所有患者均在本院进行SMI检查,以病理活检结果作为金标准,评估彩色多普勒超声与SMI技术在辅助诊断乳腺微小结节良恶性方面的价值,特别是对血流情况的评估,分析两种方法对乳腺微小结节良恶性诊断价值。结果:根据病理结果将患者分为良性组36例和恶性组24例。经SMI技术对BI-RADS 4类乳腺微小结节进行分级调整,其中良性病例有24例因血流较少而降至3类,3例因血流丰富而提高至5类;恶性病例有1例因血流较少而降至3类,16例因血流丰富而提高至5类;超声及SMI技术检测良、恶性病灶组间血流级别分布差异比较,从统计学角度分析,差异具有统计学意义(P<0.05);彩色多普勒超声法检测60例患者中有36.67%(良性6例、恶性16例)为血流丰富者,而SMI法中有63.33%(良性19例、恶性19例)为血流丰富者,相比较明显增多,从统计学角度分析,差异具有统计学意义(χ^(2)=8.533,P=0.003);彩色多普勒技术鉴别乳腺微小结节良恶性的敏感度为75.00%,特异度为83.33%。而SMI的敏感度为83.33%,特异度为91.67%,从统计学角度分析,差异具有统计学意义(P<0.05)。结论:BI-RADS 4类乳腺微小结节应用SMI技术良恶性鉴别诊断价值较高,值得临床应用。Objective:To explore the diagnostic value of superb microvascular imaging(SMI)technol-ogy in differentiating benign and malignant breast nodules classified as Breast Imaging Reporting and Data System(BI-RADS)Category 4.Methods:Sixty patients admitted to Shenhe People's Hospital from May 2023 to October 2023 were selected.All patients were diagnosed with BI-RADS Category 4 breast micro-nodule by color Doppler ultrasound before surgery.All patients underwent SMI examination in our hospital,and the pathological biopsy results were used as the gold standard to evaluate the value of color Doppler ultrasound and SMI technology in assisting in the diagnosis of benign and malignant breast nod-ules,especially in evaluating blood flow conditions.The diagnostic value of both methods for benign and malignant breast nodules was analyzed.Results:According to the pathological results,the patients were divided into a benign group of 36 cases and a malignant group of 24 cases.SMI technology adjusted the classification of BI-RADS Category 4 breast micro-nodules,with 24 benign cases downgraded to Cat-egory 3 due to reduced blood flow and 3 cases upgraded to Category 5 due to rich blood flow.Among ma-lignant cases,1 was downgraded to Category 3,and 16 were upgraded to Category 5 based on blood flow assessment.Statistical analysis revealed significant differences in blood flow distribution between benign and malignant lesions detected by ultrasound and SMI(P<0.05).Among 60 patients detected by color Doppler ultrasound,36.67%(6 benign and 16 malignant)were patients with abundant blood flow,while 63.33%(19 benign and 19 malignant)were patients with abundant blood flow in the SMI method,showing a significant increase.From a statistical perspective,the difference was statistically significant(χ^(2)=8.533,P=0.003).The sensitivity and specificity of color Doppler technology in distinguishing benign and malig-nant breast nodules are 75.00%and 83.33%,respectively.The sensitivity of SMI is 83.33%,and the specificity is 91.67%.From a statisti
