摘　　要：MRI具有软组织分辨率高、多方位和多参数成像的特点,对乳腺病变诊断的准确性高于X线和超声,使得部分形态学呈良性特征而X线和超声检查定性诊断困难的病变(如囊内乳头状癌、黏液腺癌、髓样癌、化生性癌、恶性叶状肿瘤和恶性淋巴瘤等)于术前可得以明确诊断。Some breast malignancies manifested as well-circumscribed masses that are similar to benign lesions, it is not easy to differentiate them from benign lesions by conventional imaging modalities such as mammography and ultrasonography. However, it has been proved that MR imaging of the breast can fill many of clinical information gaps that are inadequately evaluated by mammography and ultrasonography due to MRI’s inherently high soft-tissue contrast. Therefore, breast MR imaging can play a substantial role in distinguishing between well-circumscribed benign and malignant breast lesions, especially in cases that are diffcult to diagnose by using conventional imaging
