| 目的 探讨MRI在乳腺髓样癌与纤维腺瘤鉴别诊断中的价值。方法 回顾性分析经病理证实的11例乳腺髓样癌（髓样癌组）及36例乳腺纤维腺瘤（纤维腺瘤组）资料，分析并比较2组MRI特征。结果 髓样癌组患者年龄大于纤维腺瘤组（t=2.791，P=0.008）。2组间病灶最大径、病灶内部强化特征、坏死及囊变征象、平扫T2WI病灶信号强度、DWI病灶信号强度及时间-信号强度曲线（TIC）类型差异均有统计学意义（P均< 0.05），而病灶数目、形态、边缘差异均无统计学意义（P均> 0.05）。结论 MRI特征有助于鉴别诊断乳腺髓样癌与纤维腺瘤。 |

| 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. |
