摘要: [摘要] 目的 探讨实时超声弹性成像对乳腺超声影像学报告及数据系统( breastimagingreportinganddata
systemultrasound , BI-RADS-US )评分 4B 类最大直径 ≤15mm 乳腺单发实性小肿块良恶性进一步鉴别诊断的价
值。方法 常规二维灰阶及彩色多普勒超声检查的 107 例乳腺单发实性小肿块患者,所有乳腺实性小肿块均按照
BI-RADS-US 分类标准评为 4B 类,然后进行实时超声弹性成像检查,分析弹性成像特征,将病灶硬度弹性图分为
Ⅰ~Ⅴ 级,与组织病理学结果进行对照研究。结果 实时超声弹性成像弹性图评 Ⅰ 、 Ⅱ 级共 44 例,均为良性; Ⅲ 级
22 例( 17 例良性, 5 例恶性); Ⅳ~Ⅴ 级共 41 例( 4 例良性, 37 例恶性)。以弹性分级 Ⅳ~Ⅴ 级为高度恶性预测指标,
其敏感度、特异度和准确度分别为 88.1% 、 93.8% 和 91.6% ,阳性预测值为 90.2% ,阴性预测值为 92.4% 。结论
实时超声弹性成像对 BI-RADS-US 评分 4B 类乳腺单发实性小肿块良恶性的进一步鉴别诊断有较高的准确性。
