| 摘 要： | 目的 探讨应用实时超声造影(RT-CEUS)灌注特征和时间-强度曲线定量参数鉴别诊断长径≤2.0 cm乳腺良恶性肿块的价值。方法 回顾性分析63例乳腺肿块患者(良性30例,恶性33例)的常规CDFI及RT-CEUS影像资料,对比良恶性乳腺肿块的造影特点及时间-强度曲线定量参数差异,并评价诊断效能。结果 恶性肿块超声造影多表现为向心性、不均匀、高增强,周边呈放射状,87.88%(29/33)边界模糊;良性肿块多表现为离心性、均匀、低增强,83.33%(25/30)边界清晰。78.79%(26/33)的恶性肿块造影后内部可见灌注缺损。定量分析显示,恶性肿块的峰值强度(PI)及时间-强度曲线上升支斜率(k)均高于良性肿块(P均<0.05),达峰时间(TP)差异无统计学意义(P>0.05)。单纯应用常规CDFI诊断长径≤2.0 cm的乳腺恶性肿块的敏感度为72.73%(24/33),特异度为73.33%(22/30),诊断准确率为73.02%(46/63);CDFI结合超声造影灌注情况的诊断敏感度为81.82%(27/33),特异度为83.33%(25/30),准确率为82.54%(52/63)。结论 RT-CEUS灌注图像特征结合时间-强度曲线定量指标有助于提高鉴别诊断长径≤2.0 cm乳腺良恶性肿块的准确性。
