【摘要】：目的分析乳腺黏液癌的MRI表现特征。方法回顾性分析经手术病理证实的34例乳腺黏液癌的MRI表现,包括病变形态、最大径、T1WI及T2WI信号特征、肿块内部强化方式及增强曲线类型、DWI信号特征及ADC值。结果 34例乳腺黏液癌单纯型22例,混合型12例。MRI示21例为肿块型,6例为非肿块型,7例为多发结节型;T1W平扫22例呈低信号,10例呈等信号,2例呈混杂高信号;T2W脂肪抑制序列20例呈高信号,13例呈不均匀高信号,1例呈低信号,19例病灶内可见低信号纤维分隔;动态增强早期呈典型环形强化11例;时间-信号曲线呈流入型11例,平台型18例,流出型5例。结论乳腺黏液癌的MRI表现有一定特点,MR检查有助于对该病的诊断。
[Abstract]:Objective to analyze the MRI features of breast mucinous carcinoma. Methods the MRI features of 34 cases of breast mucinous carcinoma proved by operation and pathology were retrospectively analyzed, including the shape of lesion, the characteristics of T1WI and T2WI signal, the enhancement mode and the type of enhancement curve. Results among 34 cases of mucinous carcinoma of the breast, 22 cases were simple type. Mixed type 12 cases. MRI showed 21 cases were mass type 6 cases were non-mass type 7 cases were multiple nodular type T 1W plain scan 22 cases showed low signal intensity and 10 cases showed isokinetic sign 2 cases showed mixed hyperintense T2W fat suppression sequence 20 cases showed high signal intensity and 13 cases showed heterogeneity. Hypointensity was seen in 1 case and hypointensity was seen in 19 cases. Typical annular enhancement was found in 11 cases of early dynamic contrast enhancement, inflow type in 11 cases of time-signal curve, plateau type in 18 cases and outflow type in 5 cases. Conclusion the MRI findings of breast mucinous carcinoma have some characteristics. Mr examination is helpful for the diagnosis of this disease.
