乳腺恶性肿块超声造影增强特征表现与组织病理对照分析

Contrast-enhanced ultrasonography findings of malignant breast lumps and its histopathologic comparison

目的探讨不同组织病理类型乳腺恶性肿块超声造影增强特征表现。方法对42例乳腺癌患者行超声造影检查,观察肿块的增强形态、强度及造影时间-强度曲线特征,并将恶性肿瘤超声造影特征与组织病理学特征进行对照分析。结果乳腺恶性肿块超声造影的特征以不均匀部分增强及整体性增强为主,并以高增强多见,肿块增强形态、强度及向周围浸润方式与不同组织病理性质有关;时间-强度曲线呈"快进慢出"或"快进快出"型,超声造影诊断乳腺癌的符合率为95%。结论乳腺恶性病灶在超声造影下呈现不同造影特征,超声造影有助于提高乳腺恶性肿瘤的诊断准确率。

Objective To explore the contrast-enhanced ultrasonography findings of different malignant breast lumps in different pathologic types. Methods Forty-two patients with breast cancer underwent contrast-enhanced ultrasonography to observe the enhanced tumor morphology, intensity and contrast time-intensity curves and to compare the ultrasound imaging features of malignant tumors and histopathologic features. Results The ultrasound imaging of malignant tumors were mainly characterized by local asymmetrical enhancement and global enhancement, mostly hyperenhancement. The enhanced tumor morphology, intensity and infiltration outward were correlated with the different pathological nature. The time-intensity curve was in fast-in and slow-out type or fast-in and fast-out type. The accordance rate of contrast-enhanced ultrasonography was 95% for breast cancer. Conclusion The contrast-enhanced ultrasonography features of malignant breast tumors are various, and it contributes to improving the diagnostic accuracy of malignant breast tumors.
