摘　　要：目的:探讨MRI对乳腺癌的综合诊断价值。材料和方法:随机选择临床和（或）乳腺钼靶片疑有肿瘤的患者进行前瞻性系列MRI检查,将其中58例乳腺癌作为研究对象。女性57例,男性1例。所有病例均经手术病理或活检证实。分别从病灶的信号特点、形态学、强化模式及时间-信号强度曲线等方面进行分析和诊断,并评估MRI的综合价值。结果:58例乳腺癌中浸润性导管癌48例,导管原位癌3例,浸润性小叶癌3例,小叶原位癌1例,髓样癌2例及纤维腺瘤恶变1例。根据乳腺癌病灶的信号及形态学、强化模式、时间-信号强度曲线及各因素的综合诊断正确率分别为89.7％,77.6％,79.3％-91.4％和94.8％,病灶的检出率达100％。结论:MRI检查对乳腺癌检出和定性诊断具有重要价值。Purpose: To investigate the comprehensive value of sequential MRI including dynamic contrast - enhanced scan in diagnosing breast carcinoma. Materials and Methods: The patients suspicious of breast tumors clinically and/or mammographically received the sequential MRI study prospectively, and the patients who were confirmed to suffer from breast carcinoma surgico - pathologically or by biopsy were recruited into this study. Results: The study population consisted of invasive ductal carcinomas(n = 48), ductal carcinomas in situ(n = 3), invasive lobular carcinoma(n = 3), lobular carcinoma in situ (n = 1), medullary carcinoma(n = 2) and fibroadenoma with malignancy(n = 1) . The diagnostic accuracy of MRI in breast carcinoma based on the morphology, enhanced mode, time - signal intensity curve and the combination of three aforementioned parameters were 89. 7% , 77.6 % , 79.3 % - 91.4 % and 94.8 % , respectively. Conclusion: MRI of breast could be of great significance in diagnosing breast cancer.
