用0.3特斯拉超导磁体对10名正常志愿者和45名乳腺异常患者进行了磁共振检查。在所有患者中，MR检测到与乳房X光或计算机断层扫描(CT)上看到的病理区域相对应的异常。在囊性病变和乳腺组织不对称发育异常的患者中，MR明显优于乳房X光检查。磁共振图像上的异常表现为相对于邻近正常导管和脂肪组织的低信号区域。MR上病变的形态可以区分良性和恶性病变。
Ten normal volunteers and 45 patients with breast abnormalities were examined with magnetic resonance (MR), utilizing a 0.3-tesla superconducting magnet. In all patients, MR detected an abnormality that corresponded to the area of pathology seen on either a mammogram or computed tomographic (CT) scan. An appreciable advantage of MR over mammography was observed in patients with cysts and in those with areas of asymmetric dysplastic breast tissue. Abnormalities on MR images appeared as areas of low signal intensity relative to adjacent normal ductal and fatty tissue. The configuration of a lesion on MR permitted distinction between a benign and a malignant process.
