【摘要】：目的:探讨不同病灶大小、病理类型及组织学分级的乳腺癌超声造影特点是否有差异。方法 :回顾性分析113例乳腺癌患者119个病灶的超声造影灌注模式,分析所有病例病变区域的超声造影增强特点及模式,包括增强范围是否大于二维超声显示、增强强度、造影剂分布情况、造影剂进入肿瘤顺序、造影模式、是否有穿支血管、是否有灌注缺损等指标,术后收集乳腺癌大小、病理类型并分析组织学分级,分析其超声造影特征与病灶大小、病理类型、组织学分级的关系。结果:≤2 cm的乳腺癌更倾向于低增强或等增强,无灌注缺损及穿支血管;2 cm的乳腺癌倾向于高增强、存在灌注缺损及穿支血管等造影特征(P0.05)。但超声造影增强范围是否大于二维超声、造影剂分布特点、造影剂进入肿瘤的顺序、造影模式的差异与病灶大小无关(P0.05)。乳腺癌组织学分级Ⅲ级肿块出现造影后高增强、周边增强、速升缓降的比率高于组织学Ⅰ、Ⅱ级肿块(P0.05),而超声造影的增强范围、造影剂进入肿瘤的顺序、是否有灌注缺损、是否有穿支血管在乳腺癌不同组织学分级间无差异(P0.05)。结论:病灶大小和组织学分级对超声造影特征的影响要强于肿瘤病理类型,乳腺癌超声造影的表现与肿瘤大小及组织学分级的变化密切相关,乳腺癌的超声造影特点对组织学分级有一定提示作用。
[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，
