Magnetic resonance imaging (MRI) and computed tomography (CT) were compared in four children who had evidence of intracranial injury caused by shaking. All children had intracranial bleeding, neurologic impairment, and history or physical examination findings suggestive of child abuse. Three had bilateral retinal hemorrhages, and three had visual impairment. MRI revealed bilateral subdural hematomas in all four children, but CT showed this in only one. Skull fractures in one patient were visualized by CT alone. MRI alone demonstrated posterior fossa bleeding in one patient and intraparenchymal bleeding in another; an additional patient in whom CT showed relatively diffuse atrophy also had defined areas of focal atrophy apparent on MRI. Subarachnoid hemorrhages were equally well detected using CT or MRI. Overall, MRI was superior to CT for detection of intracranial injury caused by shaking, and may help to document milder instances of this form of child abuse.
对4名有摇晃导致颅内损伤证据的儿童进行了磁共振成像（MRI）和计算机断层扫描（CT）检查。所有儿童均有颅内出血、神经功能损害，且病史或体格检查结果提示存在虐待儿童情况。3名儿童有双侧视网膜出血，3名有视力损害。MRI显示所有4名儿童均有双侧硬膜下血肿，但CT仅显示1例。仅CT发现1例患者有颅骨骨折。仅MRI显示1例患者有后颅窝出血，另1例有脑实质内出血；还有1例患者CT显示相对弥漫性萎缩，而MRI显示有明确的局灶性萎缩区域。蛛网膜下腔出血在CT或MRI检查中检出情况相同。总体而言，MRI在检测摇晃导致的颅内损伤方面优于CT，可能有助于记录这种形式虐待儿童的较轻病例。
