摘要
目的:探讨MRI增强扫描在乳腺良、恶性肿块鉴别诊断中的应用价值。方法:回顾性分析乳腺病变患者40例的MRI增强扫描结果,评价病灶的形态学特征及时间-信号强度曲线类型。结果:20例恶性病变中,环形强化或边缘强化15例,时间-信号强度曲线Ⅲ型14例(70%)。良性肿块呈整体性强化或从中心开始强化,时间-信号强度曲线Ⅰ型17例(85%)。结论:乳腺肿块呈环状或边缘强化、毛刺状形态和Ⅲ型时间-信号强度曲线均提示恶性,应行肿块活检或切除术。肿块边缘光滑和Ⅰ型曲线均提示良性,可随访观察。
Objective:To evaluate the application value of MRI enhanced scan in differential diagnosis of benign and malignantbreast tumors.Methods:The MRI enhanced scan findings of 40 cases of patients with breast lesions were analyzed retrospectively.The morphological characteristics and the types of time-signal curves intensity of the lesions were evaluated.Results:Among 20cases of malignant lesions,15 cases had ring enhancement or edge enhancement.14 cases had type Ⅲ of time-signal intensitycurves (70% ).Benign tumor had overall enhancement or strengthened from the center,and 17 cases had type Ⅰ of time-signalintensity curves (85% ).Conclusion:Ring or edge enhancement,burr shape and type Ⅲ of time-signal intensity curves whichindicated malignancy,and the tumor biopsy or resection should be given.The smooth tumor margin and type Ⅰ of time-signalintensity curves indicated benign and should be followed up.
