The majority of salivary gland tumors occur in the parotid glands. Characterization (ie, benign or malignant, and histological type), location (deep or superficial), and invasion into the neighboring tissues of parotid tumors determine preoperative treatment planning. MRI gives more information than other imaging methods about the internal structure, localization, and relationship with other tissues of parotid tumors. Functional MRI methods (diffusion-weighted imaging, dynamic contrast-enhanced MRI, perfusion-weighted MRI, MR spectroscopy, etc.) have been increasingly used recently to increase the power of radiologists to characterize the tumors. Although they increase the workload of radiologists, the combined use of functional MRI methods improves accuracy in the differentiation of the tumors. There are a wide range of studies in the literature dealing with the combined use of different functional imaging methods in combination with conventional sequences. The aim of the present review is to evaluate conventional and functional/advanced MR methods, as well as multiparametric MRI applications combining them in the diagnosis of parotid gland tumors.

大多数唾液腺肿瘤发生在腮腺。腮腺肿瘤的特征（即良性或恶性和组织学类型）、位置（深部或浅部）以及对相邻组织的侵犯决定了术前治疗计划。与其他成像方法相比，MRI 提供了更多关于腮腺肿瘤的内部结构、定位和与其他组织关系的信息。功能性 MRI 方法（扩散加权成像、动态对比增强 MRI、灌注加权 MRI、磁共振波谱等）最近越来越多地用于提高放射科医生对肿瘤进行特征描述的能力。尽管它们增加了放射科医生的工作量，但功能性 MRI 方法的联合使用提高了肿瘤的鉴别准确性。文献中有大量研究涉及不同功能成像方法与常规序列的联合使用。本综述的目的是评估常规和功能/高级 MRI 方法，以及结合这些方法的多参数 MRI 应用在腮腺肿瘤诊断中的应用。证据水平：5 级技术功效：3 级 J. 磁共振成像 2020；52:11-32.
