1、超声造影在附件区肿块良恶性鉴别诊断中的应用价值吴莹熊雯陈琴(四川省医学科学院?四川省人民医院超声科四川成都610072)【摘要】目的:探讨超声造影在附件区肿块良恶性鉴別诊断中的应用价值。方法：回顾性分析在我院接受超声造影检查的附件区肿块病例20例，观察比较附件区良恶性肿块不同的造影灌注增强模式和肿瘤血管的形态学特征，并评估超声造影对附件区肿块良恶性鉴别诊断的准确性。结果：卵巢恶性肿瘤超声造影多表现为快速高增强，肿瘤内血管较丰富走形迂曲不规则，其内均可见粗大扭曲的穿支血管；附件区良性肿块多表现为无增强或环状低增强，血管稀少细小平直,多呈缓慢点状或短条状低增强。超

2、声造影对附件区肿块良恶性鉴别诊断的敏感度为100%,特异度为92.3%,准确度为93.8%o结论：超声造影显著提高了附件区肿块内微小血管的显示，能够更准确地评价附件区肿块内血管形态分布及循环灌注，对附件区肿块良恶性鉴别诊断具有较高的价值。【关键词】超声检查；造影剂；诊断；附件区；肿块【中图分类号】R445【文献标识码】A【文章编号】2095-1752(2016)13-0044-02Applicationofcontrast-enhancedultrasoundfordifferentiationofmalignantfrombenignadnexalmasse
