A great deal of information is now available regarding the range of magnetic resonance imaging (MRI) features of many primary and secondary brain tumors from dogs. In this review, these canine neoplasms are grouped into meningeal masses, ventricular masses, intra-axial enhancing lesions, intra-axial mildly to non-enhancing lesions, and multifocal lesions. For each of these patterns, the major and sporadic neoplastic differential diagnoses are provided, and guidance on how to rank differential diagnoses for each individual patient is presented. The implication of MRI features such as contrast-enhancement, signal intensities and location is discussed. However, the information garnered from MRI must be correlated with all available clinical information and with epidemiological data before creating a differential diagnosis.
目前已有大量关于犬类原发性和继发性脑肿瘤的磁共振成像（MRI）特征范围的信息。在本综述中，这些犬类肿瘤被分为脑膜肿块、脑室肿块、轴内强化病变、轴内轻度至无强化病变以及多灶性病变。针对每种模式，提供了主要和散发性肿瘤的鉴别诊断，并给出了如何对每个患者的鉴别诊断进行排序的指导。讨论了MRI特征如对比增强、信号强度和位置的意义。然而，在进行鉴别诊断之前，从MRI获得的信息必须与所有可用的临床信息以及流行病学数据相关联。
