摘 要:目的探讨小乳癌高频声像图及彩色能量多普勒显像特征,探寻超声诊断小乳癌的有效指标。方法采用GELogiq9彩色超声诊断仪对49例乳腺内直径小于2cm的实质性肿块进行常规超声与彩色多普勒血流图、能量图显像,获取肿块二维影像、血流分布数量、采集病变内部恒定的动脉血流峰值流速(Vmax)、阻力指数(RI)等多参数指标,并与术后病理对照,分析良恶性小肿块可能的鉴别指标。结果恶性组显示纵横比≥0.8;边界模糊、蟹足状;肿块内探及簇状沙砾钙化,以上指标与良性组比较,差异均有显著性(P<0.05)。良恶性病灶内血流均不明显,差异无显著(P>0.05)。结论对小乳癌诊断需要进行多参数的综合分析,病灶纵横比值、边缘、簇状微钙化比血流测定更有鉴别意义。Objective To investigate the features of small breast cancers using uhrasonography, color Doppler flow imaging (CDFI) and color power angiography (CPA) to find the indexes for differenciating small breast cancers from benign lesions. Methods Forty - nine cases of breast tumors with diameter under 2 cm were examined on uhrasonography, CDFI and CPA. Some indexes were obtained including the description of the tumor boundary, the ratio of longitudinal and transverse measurements, clustered microcalifications, vascularity within tumors, maximum flow velocity (Vmax) and resistant index (RI). Results 18 of 49 malignant tumors confirmed by surgery and pathology, showed blurred boundary, the ratio of longitudinal and transverse measurements ≥0.8 and clustered microcalifications; The difference of the indexes in the ratio of longitudinal and transverse measurements, blurred boundary, and clustered microcalifications between benign and malignant groups was significant (P〈0.05). However, the difference in hypervascularity between benign and malignant groups was not significant ( P 〉 0.05 ). Conclusion The tumor tend to be malignant if it has blurred boundary, the ratio of longitudinal and transverse measurements ≥0.8 and clustered microcalifications, Hypervascularity is not an important factor in the differenciation.
