摘要 目的研究动态增强磁共振显示的乳腺病灶周围血管征(AVS)的诊断价值及其与组织病理学特征的关系。方法对219例乳腺疾病患者行乳腺动态增强磁共振检查,在减影图及3D-MIP图像上进行评价,分析AVS阳性对乳腺癌诊断的敏感性、特异性,以及与病变大小、不同组织学类型和分级之间的关系。结果恶性肿瘤与良性病变、原位癌与浸润癌、病灶直径≥20 mm与<20 mm的AVS阳性率比较均有统计学差异(P均<0.05),而浸润性导管癌与浸润性小叶癌比较无统计学差异。AVS阳性率与恶性肿瘤大小具弱正相关,与肿瘤分级无关。AVS对恶性肿瘤的敏感性为54%,特异性为88%,阳性预测率87%。结论 AVS与乳腺恶性病变具有良好的相关性,对乳腺良、恶性病变的鉴别具有一定价值,可作为辅助诊断的间接征象,提高临床诊断的准确率。
