| 摘 要： | 目的 探讨动态增强MRI对早期乳腺癌的诊断价值.方法 分析20例早期乳腺癌动态增强MRI资料.其中,导管内乳头状癌2例,导管原位癌4例,导管原位癌伴微浸润性12例,小叶原位癌2例.总结早期乳腺癌特征性MRI表现.结果 (1)病灶增强MRI形态特征:局灶性强化2例;导管样及段样强化8例;肿块状强化10例,其中的9例肿块边缘为毛刺及不规则,1例边缘光滑;边缘强化7例,其中的2例均匀中心强化,1例分隔强化.乳腺影像报告和数据系统(BI-RADS)分级:1级1例,3级2例,其余为4级或5级.(2)X线检查结果:阴性3例,微小簇状钙化5例,线样钙化2例,肿块6例,结构扭曲2例,斑片阴影2例.BI-RADS分级:1级3例,2级1例,3级2例,其余为4级或5级.(3)16例患者早期增强率≥60%,16例信号强度-时间(SI-Time)曲线为A型,3例为B型,1例为C型.结论 早期乳腺癌MRI表现具有一定特征性,动态增强MRI联合X线可提高其诊断准确性. |

| Abstract: | Objective To investigate the value of dynamic enhanced magnetic resonance imaging(MRI) in the diagnosis of early breast cancer.Methods The dynamic enhanced MRI features of 20 cases with early breast cancer confirmed by operation and pathology were analyzed retrospectively.Of 20 cases,2 cases were intraductal papillary carcinoma,4 cases were ductal carcinoma in situ(DCIS),12 cases were DCIS with small invasive foci,2 cases were lobular carcinoma in situ.The characteristic MRI features of early breast cancers... |
