| 摘 要： | 目的探讨动态增强MRI（dynamic enhanced MRI,DCE-MRI）对乳腺癌和乳腺纤维腺瘤的鉴别诊断价值。方法选择经病理证实的乳腺癌患者30例,乳腺纤维腺瘤患者19例,对DCE-MRI检查资料进行回顾性分析,分析内容：病灶形态学及时间信号强度曲线（timesignalintensitycurve,TIC）,早期强化率。结果 30例乳腺癌中,形态不规则、有毛刺、边界模糊毛糙26例,强化方式多为不均匀或环形强化,TIC曲线多为III型和Ⅱ型。乳腺纤维腺瘤19例中,形态多呈类圆形或分叶状,边界光整,17例。强化方式多为均匀强化或无明显强化,TIC多为I型和IV型。乳腺癌和纤维腺瘤在形态学特征、强化方式及TIC类型上差异有统计学意义。结论 DCE-MRI依据病灶的形态特征、强化方式、早期增强率及TIC类型可以很好地鉴别乳腺癌和纤维腺瘤。

| Abstract: | Objective To evaluate dynamic enhanced MRI (DCE-MRI) findings their differential diagnostic value between the breast carcinoma and breast fibroadenoma. Methods DCE-MRI images and contrast enhancement characteristics of 49 cases verified by histopathology were reviewed. 30 patients were breast cancer and the rest were breast fibroadenoma. The morphology of lesion, the time signal intensity curve (TIC), the early enhancement ratio were analyzed respectively. Results 26 cases of breast cancer showed irregular ... |
