Abstract Objective: To retrospectively evaluate the diagnostic value of breast MRI in different types of mucinous adenocarcinoma of the breast. Methods: A total of 18 patients undergone surgery were retrospectively collected in our hospital, who were diagnosed with mucinous adenocarcinoma by pathology, including 12 mixed mucinous adenocarcinoma and 6 pure mucinous adenocarcinoma. MR features of two groups were compared. Results: The different MR features of the two groups including: ①Different boundary: 75.0%(9/12) pure mucinous adenocarcinoma had smooth edge, 66.7%(4/6) mixed mucinous adenocarcinoma had speculated edge. ②Different signal intensity on T2WI: 83.3%(10/12) pure mucinous adenocarcinoma were extremely high signal intensity, 83.3%(5/6) mixed mucinous adenocarcinoma were high-low mixed signal intensity. ③Different ADC value: the mean ADC value of pure mucinous adenocarcinoma ((1.9±0.3)×10-3 mm2/s) were higher than that of mixed mucinous adenocarcinoma((1.1±0.2)×10-3 mm2/s). All the results above were regarded as statistically significant(P<0.05). Conclusion: There are significant differences of pure mucinous adenocarcinoma and mixed mucinous adenocarcinoma on MRI in the boundary of tumor, T2 signal intensity and ADC value. MRI is an effective imaging method for diagnosis of mucinous breast carcinoma, and to identify pure mucinous adenocarcinoma and mixed mucinous adenocarcinoma.
