Using gadolinium-DTPA enhanced MRI we analyzed the enhancement characteristics of palpable breast masses in 23 patients--10 cancers and 13 benign lesions. The most specific finding for separating benign from malignant lesions was a ratio of maximum intensity change divided by the time interval during which this first occurred. Designated ranges of this ratio were specific for benign disease and sensitive for malignancy in this small patient group. Three of eight fibroadenomas exhibited enhancement patterns indistinguishable from cancer.
我们使用钆喷酸葡胺增强磁共振成像（MRI）分析了23例可触及乳腺肿块患者的增强特征，其中10例为癌症，13例为良性病变。区分良性与恶性病变的最具特异性的发现是最大强度变化除以首次出现该变化的时间间隔的比值。在这个小患者群体中，该比值的特定范围对良性疾病具有特异性，对恶性肿瘤具有敏感性。8例纤维腺瘤中有3例表现出与癌症难以区分的增强模式。
