摘　　要：乳腺癌已成为全球第一大癌症,严重威胁女性健康。磁共振成像技术以其多参数、高软组织分辨率及无电离辐射等优点,已越来越多地应用于乳腺病变的良恶性鉴别。随着近年来磁共振技术的飞速发展,新的成像方法不断涌现,为乳腺病变的良恶性检出提供了更有价值的参考依据。其中,超快速磁共振动态对比增强成像、合成磁共振成像、磁共振指纹打印技术及一系列高级扩散加权成像技术(体素内不相干运动成像、扩散峰度成像和拉伸指数模型成像)均可以从不同角度描述乳腺病变潜在的组织学或病理学特征,为良恶性鉴别提供有力支撑。本文将从成像原理、技术特点以及临床应用等多个层面,系统地阐述上述磁共振成像新技术对乳腺病变良恶性的鉴别诊断价值。Breast cancer has become the most commonly cancer worldwide and is a serious threat to women's health.Magnetic resonance imaging,with its multi-parameter,multi-sequence,high soft tissue resolution and absence of ionizing radiation,is increasingly being used to identify benign and malignant breast lesions.With the rapid development of magnetic resonance technology in recent years,new imaging methods have emerged,providing more and more valuable references for the detection of benign and malignant breast lesions.Among them,ultrafast dynamic contrast-enhanced magnetic resonance imaging,synthetic magnetic resonance imaging,magnetic resonance fingerprinting and a series of advanced diffusion weighted imaging techniques,such as intravoxel incoherent movement,diffusion kurtosis imaging and stretched exponential model,can describe the underlying histological and pathological features of breast lesions from different perspectives and provide strong support for benign and malignant identification.This article will systematically and thoroughly describe the value of these new magnetic resonance imaging techniques for the differential diagnosis of benign and malignant breast lesions from various perspectives,including imaging principles,technical features and clinical applications.
