摘　　要：MRI具有极佳的软组织分辨率，近年来，该技术越来越广泛的应用于乳腺疾病的诊断。乳腺动态增强成像和灌注加权成像可从不同角度反映乳腺组织及病灶的血供灌注情况，弥散加权成像和磁共振波谱分析则从分子水平提供乳腺病变组织信息，磁共振乳腺导管成像为导管内病变提供了新的影像诊断方法。随着MRI技术的成熟、软硬件的迅速发展，MRI在乳腺疾病的检出和诊断方面显示出其独到的优势。MRI has excellent soft tissue resolution, and this technology is more and more widely used in breast disease diagnosis in recent years. Blood supply and perfusion through the microvascular net-work of tumor can be imaged noninvasively by dynamic contrast-enhanced MRI and perfusion-weighted imaging. Diffusion-weighted imaging and magnetic resonance spectroscopy can provide molecular information of breast lesions. Magnetic resonance ductography provides a new technology for detecting intraductal breast lesions. With MRI technology maturing and the rapid development of software and hardware, MRI shows its unique advantages in breast lesions characterization.
