摘　　要：目的探讨磁共振功能成像技术(DWI、DCE及MRS)在乳腺良恶性病变诊断中的应用价值。方法回顾性分析57例经病理证实的乳腺疾病患者的DWI、DCE及MRS资料。结果 DWI的敏感性、特异性、准确性分别为83.3%、90%、87.9%;DCE-TIC的敏感性、特异性、准确性分别为70%、94.4%、77.5%;MRS的敏感性、特异性、准确性分别为77.5%、72.2%、75.8%;联合诊断的敏感性、特异性、准确性分别为90%、94.4%、91.4%。结论 DWI、DCE、MRS在乳腺良恶性病变鉴别诊断方面各有优势,联合应用可提高病变诊断的准确性。Objective To explore the value of magnetic resonance functional imaging（ DWI,Diffusion Weighted Imaging;DCE,Dynamic Contrast Enhance; MRS,Magnetic Resonance Spectroscopy） in the diagnosis of benign and malignant breast lesions. Methods We retrospectively analyzed DWI,DCE and MRS data of 57 of patients with mammary gland disease. All patients were confirmed by pathology. Results The sensitivity,specificity and accuracy of DWI are 83. 3%,90% and 87. 9% respectively. The sensitivity,specificity and accuracy of DCE are 70%,94. 4%,77. 5% respectively. The sensitivity,specificity and accuracy of MRS are 77. 5%,72. 2%,75. 8% respectively. The sensitivity,specificity and accuracy of combined diagnosis are 90%,94. 4%,91. 4%. Conclusion DWI,DCE and MRS have differential advantages in the diagnosis of benign and malignant breast lesions. Combined use of these three methods can improve the accuracy of disease diagnosis.
