摘　　要：目的探讨MRI多模态成像技术在乳腺良恶性病变中的诊断价值。方法采用GE Discovery 750w3.0T静音MR扫描仪,8通道乳腺专用线圈,应用MRI多模态成像技术对初次就诊患者行平扫、DCE、DWI检查,根据ACR BI-RADS-MRI对病变进行解读、诊断及分级,以病理诊断结果为“金标准”,分析MRI多模态成像技术对乳腺良恶性病变诊断的应用价值。结果乳腺良性、恶性病变在MRI多模态成像中表现不同,恶性病变以不规则形伴毛刺肿块多见,多呈不规则环状强化,少数呈线状、区域性非肿块样强化,以Ⅲ型曲线为主,ADC值较低;良性病变多表现为边界清楚的类圆形肿块,呈均匀性强化,以Ⅰ型曲线为主,ADC值较恶性病变高。结论MRI多模态成像技术可以清晰显示良、恶性病变的形态、血供、细胞代谢水平差异,提高早期乳腺癌的诊断水平。Objective To explore the diagnostic value of MRI multimodal imaging technology in breast benign and malignant lesions.Methods GE Discovery 750 w3.0 T silent MR scanner,8-channel breast coils,and MRI multimodal imaging technology were used to perform plain scan,DCE,and DWI examinations on the first visit patients,and the lesions were interpreted according to ACR BI-RADS-MRI,Diagnosis and classification,with pathological diagnosis as the gold standard,analyze the diagnostic value of MRI multimodal imaging technology for breast benign and malignant lesions.Results The appearance of benign and malignant breast lesions was different in MRI multimodal imaging.Malignant lesions were mostly irregular with burr masses,most of which showed irregular ring enhancement,a few showed linear and regional non-mass enhancement,with Ⅲ Type-Ⅰ curves are dominant,and ADC values are low;benign lesions are mostly round-shaped masses with clear boundaries,showing uniform enhancement.Type Ⅰ curves are dominant,and ADC values are higher than malignant lesions.Conclusion MRI multimodal imaging technology can clearly show the differences in the morphology,blood supply,and cell metabolism of benign and malignant lesions,and provide the diagnostic level of early breast cancer.
