实时超声造影成像结合多普勒血流频谱形态评价乳腺良恶性肿块的血流动力学特性

目的:利用灰阶谐波超声造影及时间-强度曲线软件支持,并对比研究乳腺良恶性肿块内血流频谱形态特征来综合分析乳腺良恶性肿块的血流动力学特性。方法:前期工作:对136个乳腺良恶性肿块提取了内部血流频谱,后期对另16个乳腺良恶性肿块进行了超声造影检查。结果:乳腺良恶性肿块内部血流频谱形态存在差异,乳腺癌的血流频谱形态可分为4型;造影后乳腺良恶性肿块的时间-强度曲线形态及参数存在差异。结论:实时超声造影成像技术结合多普勒血流频谱形态分析为乳腺癌的早期诊断开辟了一条新的思路。

Real contrast ultrasound combined with blood spectrum morphology in determining the character of blood dynamics in breast tumor

Objective: Utilizing grey-harmonious contrast ultrasound combined with time-strength curve and compared with blood spectrum morphology to analysis blood dynamic character of breast tumor. Methods: Prophase research: pulse Doppler was added to 136 breast tumors to withdraw the blood spectrum. Another 16 breast tumors were checked with contrast ultrasound. Results: Blood spectrum morphology of malignant tumor and benign tumor was different. Blood spectrum morphology in breast cancers can be divided into 4 types. Morphology and parameter of time-strength curve of malignant and benign breast tumor were different. Conclusions: Blood spectrum morphology combined with real contrast ultrasound in determining vascular character of breast tumor can provide more valuable information in early diagnosing breast cancer.
