Abstract: Objective To explore MRI features of mucinous breast carcinoma.Methods MR data of 34 patients with mucinous breast carcinoma confirmed by histopathology were analyzed retrospectively,including lesions morphology,maximum diameter,T1WI and T2WI signal characteristics,features of internal reinforcement,time-intensity curve (TIC) type,DWI and ADC characteristics.Results There were 22 cases of pure tumors and 12 mixed tumors;21 cases were mass types,6 cases were non-mass types,and 7 cases were multiple nodular types.On T1WI,there were low signal intensity in 22 case,equal signal in 10 cases,and mixed high signal in 2 cases.On fat suppression T2WI,20 cases showed high signal,13 cases showed mixed high signal and 1 case showed low signal,and 19 cases showed low signal fiber separation inside.Dynamic contrast enhancement showed typical circinate enhancement in 11 cases.TIC of 11 cases were wash-in types,18 cases were lateau types and 5 cases were wash-out types.Conclusion MRI features of mucinous breast carcinoma has certain characteristics.MRI is helpful to diagnosis of mucinous breast carcinoma
