摘　　要：目的探究彩色多普勒超声在乳腺良恶性肿瘤中的声像图特征及诊断价值。方法选取2021年1月-2023年8月玉山县黄家驷医院超声科筛查发现的60例乳腺肿瘤患者作为研究对象,经手术病理诊断恶性肿瘤19例、良性肿瘤41例。所有患者均接受彩色多普勒超声检查,以手术病理结果作为金标准。计算彩色多普勒超声诊断乳腺良恶性肿瘤的诊断效能(灵敏度、特异度、准确性)。比较良性、恶性肿瘤患者的超声特征、血流信号、病灶峰值血流速度以及阻力指数。结果经彩色多普勒超声发现,恶性肿瘤21例,良性肿瘤39例。彩色多普勒超声的诊断灵敏度、特异度、准确率分别为89.47%、90.24%、90.00%。与良性肿瘤患者比较,恶性肿瘤患者肿瘤形态不规则、边界不明确、回声欠均匀、钙化以及局部充盈缺损发生率更高(P<0.05);与良性肿瘤患者比较,恶性肿瘤患者Ⅱ级和Ⅲ级占比更高,0级和Ⅰ级占比更低(P<0.05);与良性肿瘤患者比较,恶性肿瘤患者PSV和RI值更高(P<0.05)。结论彩色多普勒超声诊断乳腺良恶性肿瘤具有较好的诊断效能,良性肿瘤和恶性肿瘤的血流信号强度及影像学表现存在明显差异,可将此作为诊断依据,提高诊断检出率。Objective To explore the ultrasonographic characteristics and diagnostic value of color Doppler ultrasound in benign and malignant breast tumors.Methods From January 2021 to August 2023,60 patients with breast tumor were selected as the study objects.19 cases of malignant tumor and 41 cases of benign tumor were diagnosed by operation and pathology.All patients underwent color Doppler ultrasonography,with surgical pathologic results as the gold standard.The diagnostic efficiency(sensitivity,specificity,accuracy)of color Doppler ultrasound in the diagnosis of benign and malignant breast tumors was calculated.The ultrasound features,blood flow signal,peak blood flow velocity and resistance index of benign and malignant tumors were compared.Results Totally 21 cases of malignant tumor and 39 cases of benign tumor were found by color Doppler ultrasound.The diagnostic sensitivity,specificity and accuracy of color Doppler ultrasound were 89.47%,90.24%and 90.00%,respectively.Compared with patients with benign tumors,the incidence of irregular tumor morphology,unclear boundary,uneven echo,calcification and local filling defect in patients with malignant tumors was higher(P<0.05).Compared with patients with benign tumors,the proportion of gradeⅡand gradeⅢin patients with malignant tumors was higher,and the proportion of grade 0 and gradeⅠwas lower(P<0.05).Compared with patients with benign tumors,PSV and RI values were higher in patients with malignant tumors(P<0.05).Conclusion Color Doppler ultrasound has a good diagnostic efficiency in the diagnosis of benign and malignant breast tumors,and there are obvious differences in blood flow signal intensity and imaging findings between benign and malignant tumors,which can be used as diagnostic basis to improve the diagnostic detection rate.
