Strokes, both ischemic and hemorrhagic, are the most common underlying cause of acute, non-progressive encephalopathy in dogs. In effect, substantial information detailing the underlying causes and predisposing factors, affected vessels, imaging features, and outcomes based on location and extent of injury is available. The features of canine strokes on both computed tomography (CT) and magnetic resonance imaging (MRI) have been described in numerous studies. This summary article serves as a compilation of these various descriptions. Drawing from the established and emerging stroke evaluation sequences used in the investigation of strokes in humans, this summary describes all theoretically available sequences. Particular detail is given to logistics of image acquisition, description of imaging findings, and each sequence's advantages and disadvantages. As the imaging features of both forms of strokes are highly representative of the underlying pathophysiologic stages in the hours to months following stroke onset, the descriptions of strokes at various stages are also discussed. It is unlikely that canine strokes can be diagnosed within the same rapid time frame as human strokes, and therefore the opportunity for thrombolytic intervention in ischemic strokes is unattainable. However, a thorough understanding of the appearance of strokes at various stages can aid the clinician when presented with a patient that has developed a stroke in the days or weeks prior to evaluation. Additionally, investigation into new imaging techniques may increase the sensitivity and specificity of stroke diagnosis, as well as provide new ways to monitor strokes over time.

犬脑缺血性和出血性疾病的成像。

缺血性和出血性中风是犬急性，非进行性脑病的最常见根本原因。实际上，可获得大量信息，这些信息详细说明了潜在的原因和诱发因素，受影响的血管，影像学特征以及基于受伤部位和程度的结果。在许多研究中都描述了计算机断层扫描（CT）和磁共振成像（MRI）上的犬中风的特征。本摘要文章是这些各种描述的汇总。从在人类中风研究中使用的已建立的和新兴的中风评估序列中汲取灵感，此概述描述了所有理论上可用的序列。特别详细地介绍了图像采集的物流，成像结果的描述以及每个序列的信息。的优缺点。由于两种形式的中风的影像学特征都可以很好地代表中风发作后数小时至数月的潜在病理生理学阶段，因此还讨论了各个阶段中风的描述。不可能在与人类中风相同的快速时间内诊断出犬中风，因此无法获得在缺血性中风中进行溶栓治疗的机会。但是，全面了解中风在各个阶段的出现，可以为临床医生提供在评估前几天或几周内已发展为中风的患者。此外，对新的成像技术的研究可能会增加中风诊断的敏感性和特异性，并提供新的方法来随时间监视中风。由于两种形式的中风的影像学特征都可以很好地代表中风发作后数小时至数月的潜在病理生理学阶段，因此还讨论了各个阶段中风的描述。不可能在与人类中风相同的快速时间内诊断出犬中风，因此无法获得在缺血性中风中进行溶栓治疗的机会。但是，全面了解中风在各个阶段的出现，可以为临床医生提供在评估前几天或几周内已发展为中风的患者。此外，对新的成像技术的研究可能会增加中风诊断的敏感性和特异性，并提供新的方法来随时间监视中风。由于这两种形式的中风的影像学特征都可以很好地代表中风发作后数小时至数月的潜在病理生理阶段，因此还讨论了各个阶段中风的描述。不可能在与人类中风相同的快速时间内诊断出犬中风，因此无法获得在缺血性中风中进行溶栓治疗的机会。但是，全面了解中风在各个阶段的出现，可以为临床医生提供在评估前几天或几周内已发展为中风的患者。此外，对新的成像技术的研究可能会增加中风诊断的敏感性和特异性，并提供新的方法来随时间监视中风。
