【摘要】：目的:探討不同病灶大小、病理類型及組織學分級的乳腺癌超聲造影特點是否有差異。方法 :回顧性分析113例乳腺癌患者119個病灶的超聲造影灌注模式,分析所有病例病變區(qū)域的超聲造影增強特點及模式,包括增強范圍是否大于二維超聲顯示、增強強度、造影劑分布情況、造影劑進入腫瘤順序、造影模式、是否有穿支血管、是否有灌注缺損等指標,術(shù)后收集乳腺癌大小、病理類型并分析組織學分級,分析其超聲造影特征與病灶大小、病理類型、組織學分級的關(guān)系。結(jié)果:≤2 cm的乳腺癌更傾向于低增強或等增強,無灌注缺損及穿支血管;2 cm的乳腺癌傾向于高增強、存在灌注缺損及穿支血管等造影特征(P0.05)。但超聲造影增強范圍是否大于二維超聲、造影劑分布特點、造影劑進入腫瘤的順序、造影模式的差異與病灶大小無關(guān)(P0.05)。乳腺癌組織學分級Ⅲ級腫塊出現(xiàn)造影后高增強、周邊增強、速升緩降的比率高于組織學Ⅰ、Ⅱ級腫塊(P0.05),而超聲造影的增強范圍、造影劑進入腫瘤的順序、是否有灌注缺損、是否有穿支血管在乳腺癌不同組織學分級間無差異(P0.05)。結(jié)論:病灶大小和組織學分級對超聲造影特征的影響要強于腫瘤病理類型,乳腺癌超聲造影的表現(xiàn)與腫瘤大小及組織學分級的變化密切相關(guān),乳腺癌的超聲造影特點對組織學分級有一定提示作用。
[Abstract]:Objective: to investigate whether there are differences in contrast-enhanced features of breast cancer with different lesion size, pathological type and histological grade. Methods: the perfusion patterns of 119 lesions in 113 patients with breast cancer were analyzed retrospectively, and the enhancement characteristics and patterns in all lesions were analyzed, including whether the range of enhancement was larger than that of two-dimensional ultrasonography and the intensity of enhancement. The distribution of contrast agents, the sequence of contrast agents into the tumor, the pattern of contrast, whether there are perforating vessels, whether there are perfusion defects, and so on. The size, pathological types and histological grading of breast cancer were collected after operation. The relationship between contrast-enhanced ultrasound features and lesion size, pathological type and histological grade was analyzed. Results: the breast cancer with 鈮，
