Magnetic resonance imaging (MRI) of the head and spine exceeds the sensitivity of computed tomography (CT) in detecting parenchymal lesions of the brain and spinal cord. MRI should be employed as a screening examination, particularly in patients suspected of having demyelinating diseases. CT continues to be the imaging technique of choice in evaluation of trauma, accurately depicting bony abnormalities and intracranial hemorrhage in evaluation of the spinal column and suspected disc herniation and in uncooperative patients.
头部和脊柱的磁共振成像（MRI）在检测脑和脊髓的实质病变方面比计算机断层扫描（CT）更具敏感性。MRI应作为一种筛查检查，特别是在怀疑患有脱髓鞘疾病的患者中。在评估创伤时，CT仍然是首选的成像技术，在评估脊柱、疑似椎间盘突出以及不配合的患者时，它能准确显示骨骼异常和颅内出血。
