超声造影增强模式在乳腺良恶性肿块鉴别诊断中的价值

目的探讨超声造影增强模式对乳腺良恶性肿块鉴别诊断的价值。方法选择40例经病理组织检查证实的乳腺肿瘤患者,均为女性,年龄25～54岁,平均年龄35岁。其中良性肿块25例,恶性肿块15例。使用Siemens Sequoia 512彩色多普勒超声诊断仪,造影剂采用SonoVue,行超声造影增强方式检查。结果乳腺良恶性肿块超声增强方式不同,良性肿块以整体不同程度地均匀型增强改变为主(80%,20/25),恶性肿块主要表现为不均匀增强或周边增强(86.7%,13/15)。结论乳腺良恶性肿块超声造影增强模式不同,可为鉴别诊断提供帮助。

Diagnostic value of enhancement patterns of contrast-enhanced ultrasound in differential diagnosis of benign and malignant breast tumors

Objective To study the diagnostic value of enhancement patterns of contrast-enhanced ultrasound in breast tumors.Methods A total of 40 patients with breast tumors which confirmed by histopathology were enrolled,females,aged 25-54 years old,mean age 35 years old,25 of benign tumors and 15 of malignant.All of them received contrast-enhanced ultrasound by Siemens Sequoia 512 color Doppler ultrasonic,and contrast agent was SonoVue.Results There were different enhancement patterns in benign and malignant tumors,which manifested the integrity uniformity changed in benign group(80 %,20/25) and non-homogeneous enhancement and peripheral enhancement changed in malignant group(86.7 %,13/15).Conclusion It is demonstrated that the enhancement patterns of contrast-enhanced ultrasound in breast tumors are different greatly,which could be used to make differential diagnosis in benign and malignant breast tumors.
