目的探讨彩色多普勒超声在乳腺良恶性肿瘤鉴别诊断中的应用价值。方法 80例乳腺肿瘤患者作为研究对象,经病理穿刺实验证实乳腺癌患者42例,纤维腺瘤患者38例。对所有患者行乳腺彩色多普勒超声检查,观察病灶血流信号、波动指数(PI)、阻力指数(RI)、峰值流速等血流动力学指标,并进行良恶性质鉴别诊断,与病理证实结果比较。结果彩色多普勒超声对乳腺癌及纤维腺瘤的鉴别诊断结果与病理证实结果比较,差异无统计学意义(P>0.05);良性肿瘤与恶性肿瘤的血流信号丰富程度、血流峰值流速、RI、PI指标比较,差异有统计学意义(P<0.05)。结论采用彩色多普勒超声检查乳腺肿瘤具有较高的良恶性鉴别能力,可准确检出良恶性肿瘤病灶血流动力学指标差异,同时该检查为无创性检查,较穿刺活检具有方便、快捷、经济的优势,具有临床应用及推广价值。
Objective To explore the value of color Doppler ultrasound in the differential diagnosis of benign and malignant breast tumors. Methods Totally 80 cases of breast cancer patients were selected as study objects. Forty-two cases of breast cancer and 38 cases of fibroadenoma were confirmed by pathological puncture. All the patients underwent color Doppler ultrasound examination of the breast, and the hemodynamic indexes such as lesion blood flow signal, wave index (PI), resistance index (RI) and peak flow rate were observed, and the differential diagnosis between benign and malignant features was confirmed. Results comparison. Results The results of color Doppler ultrasound in the differential diagnosis between breast cancer and fibroadenoma were not statistically significant (P> 0.05). The richness of blood flow signals, peak blood flow velocity , RI, PI indicators, the difference was statistically significant (P <0.05). Conclusion The color Doppler ultrasound examination of breast tumors with high benign and malignant ability to differentiate between benign and malignant tumor lesions hemodynamic indicators can be accurately detected at the same time as a noninvasive examination of the test, compared with needle biopsy is convenient, fast, Economic advantages, with clinical application and promotion of value.
