摘　　要：目的分析比较CT和MRI在重型颅脑损伤诊断中的应用价值。方法回顾性分析2015年1月至2016年11月收治的29例重型颅脑损伤的临床资料,均在入院后4.5 d内行CT和MRI检查,两者间隔在2 h以内。结果CT对颅骨骨折和蛛网膜下腔出血的检出率明显高于MRI(P<0.05),但CT在硬膜外血肿、硬膜下血肿、脑挫伤、弥漫性轴索损伤的检出率明显低于MRI(P<0.05),尤其对脑深部组织的小损伤灶的检出率。结论将MRI检查应用到重型颅脑损伤的诊断中可弥补CT的不足,提高确诊率,且对预后评估有重要参考价值。Objective To explore the values of MRI and CT to diagnosis severe traumatic brain injury(sTBI).Methods A retrospective analysis of 29 patients with sTBI treated in our hospital from January,2015 to November,2016 was made.CT and MRI examinations were performed within 4.5 days after the admission to hospital in all the patients.There was an interval of 2 hours between both the examinations.The outcomes of CT and MRI examinations in these 29 patients were analyzed.Results The rates of skull fracture and subarachnoid hemorrhage detected by CT were significantly higher than those by MRI(P<0.05).And the rates of epidural hematoma,subdural hematoma,brain contusion and diffuse axonal injury,especially small lesions in deep brain tissues detected by CT were significantly lower than those by MRI.Conclusions It is suggested that the value of MRI to the diagnosis of the sTBI-produced lesions,except skull fracture and subarachnoid hemorrhage,is better than that of CT.It is of great practical significance to apply MRI to the diagnosis of sTBI because the outcomes of MRI examination are more helpful to full understanding of the patients'condition.
