50例患者在头部损伤后一周内进行了磁共振成像（MRI）研究。在46名患者中发现了表明原发性脑损伤的异常，几乎是计算机断层扫描的两倍。无论损伤对意识水平的影响如何，皮质挫伤是最常见的发现。脑内病变仅见于意识丧失的患者，在42例到达医院时意识仍然受损的患者中有29例存在脑内病变。病变的大脑半球的深部白质中看到的15例患者，他们显着更频繁的昏迷患者，但也看到在患者失去意识不超过5分钟。研究结果表明，大脑半球的病变可能是创伤性意识不清的主要因素。MRI研究也可以澄清头部受伤的后遗症。
50 patients were studied by magnetic resonance imaging (MRI) within one week of a head injury. Abnormalities indicating primary brain damage were found in 46 patients, almost twice as many as with computed tomography. Cortical contusions were the most common finding, irrespective of the effect of injury on the level of consciousness. Intracerebral lesions were seen only in patients who had lost consciousness and were present in 29 of 42 patients whose consciousness was still impaired on arrival at hospital. Lesions in the deep white-matter of the cerebral hemispheres were seen in 15 patients; they were significantly more frequent in patients in coma but were also seen in patients who had lost consciousness for no more than 5 min. The findings indicate that lesions in the cerebral hemispheres may be the primary factor in traumatic unconsciousness. MRI studies may also clarify the sequelae of head injuries.
