MRI of the breast is an increasingly employed modality for breast imaging due to its relatively high sensitivity for the detection of breast carcinoma. Cumulative data indicate that MRI of the breast has relatively higher sensitivity, but lower specificity than mammography. However, data regarding the diagnostic yield for particular types of breast lesions detected via breast MRI remain scant. Over a 3.5-year period, we evaluated histological findings of 192 needle core biopsies of MRI detected breast lesions. In this series, the positive predictive value of MRI detected lesions for breast carcinoma was 20%. Invasive carcinoma was diagnosed in 16/192 (8%) and in situ carcinoma in 22/192 (11%). The most commonly detected histological finding was cystic apocrine hyperplasia (19%), a benign entity.
磁共振成像（MRI）在乳腺成像中越来越受欢迎，因为它对乳腺癌的检测具有较高的敏感性。累积数据表明，MRI 对乳腺的敏感性相对较高，但特异性低于乳房 X 线摄影术。然而，关于通过乳房 MRI 检测到的特定类型乳腺病变的诊断收益的数据仍然很少。在 3.5 年的时间里，我们评估了 192 例经 MRI 检测到的乳腺病变的针芯活检的组织学发现。在本系列中，MRI 检测到的病变对乳腺癌的阳性预测值为 20%。诊断为浸润性癌 16/192（8%），原位癌 22/192（11%）。最常见的组织学发现是囊性大汗腺增生（19%），一种良性实体。
