Abstract:
Objective To explore the value of MRI in differential diagnosis of breast medullary carcinoma and fibroadenoma.Methods Data of 11 patients with medullary carcinoma (medullary carcinoma group) and 36 patients with fibroadenoma (fibroadenoma group) confirmed with pathology were analyzed retrospectively.MRI characteristics were analyzed and compared between the two groups.Results The age of patients in medullary carcinoma group was greater than those in fibroadenoma group (t=2.791,P=0.008).There were statistical differences of the maximum diameter of lesions,internal enhancement characteristics,necrotic and cystic degeneration of lesions,un-enhanced T2WI signal intensity of lesions,DWI signal intensity of lesions and time-signal intensity curve (TIC) type (all P＜0.05),while no statistical difference of lesion numbers,morphology and edge of lesions was found between the two groups (all P＞0.05).Conclusion The features of MRI are helpful to differential diagnosis of medullary carcinoma and fibroadenoma of the breast.
