目的探讨声学造影在乳腺导管内肿瘤良恶性鉴别中的价值。方法回顾性分析30例我院收治的乳腺导管内肿瘤(包括导管内乳头状瘤、导管内原位癌及导管内乳头状癌)的常规超声、病理及声学造影的特点,比较良恶性肿瘤之间的差异。重点关注造影前后病灶径线的改变。结果病灶的大小、生长方向、主体回声、边缘、形状、周围导管扩张、病灶内钙化以及彩色多普勒显示的血流情况,在导管内乳头状瘤与导管内癌(包括原位癌和乳头状癌)两组之间,差异无统计学意义。而造影后两组病灶径线均较造影前增大,导管内癌的径线增大明显,两组之间出现显著差异(P<0.05)。结论声学造影有助于鉴别导管内肿瘤的良恶性,导管内恶性肿瘤造影后径线明显增大。
Objective To investigate the value of contrast-enhanced ultrasound in differentiating benign and malignant tumors in breast duct. Methods A retrospective analysis of 30 cases of intraductal breast tumors (including intraductal papilloma, ductal carcinoma in situ and ductal papillary carcinoma) in our hospital were compared with conventional ultrasound, pathology and acoustic imaging characteristics of benign and malignant tumors The difference between. Focus on changes in the diameter of the lesion before and after contrast. Results The size of the lesion, the direction of growth, the echogenicity of the body, the edges, the shape, the dilation of the surrounding ducts, the calcification within the lesion, and the color flow shown by color Doppler showed a significant increase in intraductal papilloma and ductal carcinoma (including carcinoma in situ and nipple Like cancer) between the two groups, the difference was not statistically significant. However, the lesion diameter of the two groups increased compared with those before angiography, and the diameter of the ductal carcinoma increased significantly. There was a significant difference between the two groups (P <0.05). Conclusions Acoustic contrast can help identify the benign and malignant intraductal tumors. The diameter of the intraductal malignant tumor after angiography is obviously increased.
