【摘要】：目的探讨乳腺实性原位乳头状癌(SPC)的MR影像表现。方法回顾性分析5例经手术病理证实的乳腺原位SPC患者的资料,观察其术前常规MR平扫、动态增强扫描及DWI表现。结果原位SPC病灶T1WI脂肪抑制梯度回波(FSPGR)序列平扫表现为等和/或稍低信号,FSE T2WI、短时反转恢复(STIR)序列平扫表现为等和/或稍高信号;动态增强MRI表现为边界清楚的椭圆形或不规则形强化,病灶内部强化均匀或不均匀。时间信号强度曲线早期快速上升,晚期呈平台型或流出型。DWI病灶均表现为高信号,ADC值1.34×10~(-3)~1.96×10~(-3) mm~2/s。结论原位SPC的MRI表现具有一定特征,可为其诊断及与其他浸润性乳腺癌的鉴别提供参考信息。
[Abstract]:Objective to investigate the MRI findings of solid in situ papillary carcinoma of the breast (SPC). Methods the data of 5 cases of breast in situ SPC confirmed by operation and pathology were analyzed retrospectively. The preoperative conventional Mr scan, dynamic contrast enhanced scan and DWI were observed. Results in situ SPC lesions, FSPGR showed isotropic and / or slightly hypointense FSE T2WI, and STIR showed isotropic and / or hyperintense signal on T 1WI. Dynamic contrast enhanced MRI showed elliptical or irregular enhancement with clear boundary and homogeneous or uneven enhancement within the lesion. The intensity curve of time signal increased rapidly in the early stage, and in the late stage, the lesions were flat or efflux. All the lesions showed high signal intensity (ADC) of 1.34 脳 10 ~ (-3) and 1.96 脳 10 ~ (-3) mm ~ (-3) / s. Conclusion MRI findings of in situ SPC have some characteristics, which can provide reference information for diagnosis and differential diagnosis of other invasive breast cancer.
