An adult greyhound was evaluated on three occasions for acute, intracranial neurologic signs. Based on magnetic resonance (MR) imaging, there were T2-hyperintense and T1-hypointense, noncontrast enhancing lesions in the cerebellum, and brain stem. Using diffusion-weighted imaging (DWI), the lesions were characterized initially by restricted water diffusion. The presumptive diagnosis on each occasion was acute ischemic cerebrovascular accident leading to infarction. This allowed us to characterize the changes in appearance of infarcted neural tissue on the standard MR sequences over time, and to confirm that the DWI could be successfully used in low-field imaging. © 2012 Veterinary Radiology & Ultrasound.
一只成年灵缇犬因急性颅内神经症状接受了三次评估。基于磁共振（MR）成像，在小脑和脑干发现了T2高信号和T1低信号、无强化的病变。使用弥散加权成像（DWI），这些病变最初表现为水弥散受限。每次的初步诊断均为急性缺血性脑血管意外导致梗死。这使我们能够描述梗死神经组织在标准MR序列上随时间的外观变化，并证实DWI可成功用于低场成像。© 2012兽医放射学与超声学。
