描述了两例雷氏综合征患者的系列MRI表现，显示弥漫性皮质和白质改变。急性期，T2加权像表现为清晰的层状高信号，增强后的T1加权像呈层状强化，沿大脑皮层两侧。慢性期平扫表现为弥漫性皮质板层高信号。这些特征性的MRI表现似乎与缺氧性脑损伤中的板层皮质坏死非常相似。MRI还显示脑白质延迟改变并伴有大脑萎缩。
Serial MRI findings are described in two patients with Reye's syndrome, demonstrating diffuse cortical and white matter changes. In the acute stage, T2-weighted images showed subtle but definite laminar high signal and contrast-enhanced T1-weighted images laminar enhancement, along the entire cerebral cortexbilateraly. In the chronic stage, unenhanced T1-weighted images showed diffuse cortical laminar high signal. These characteristic MRI features seemed very similar to those of laminar cortical necrosis in hypoxic brain damage. MRI also displayed delayed white matter changes with cerebral atrophy.
