摘　　要：目的观察CT无阳性表现的轻度脑损伤患者SWI的应用价值。方法对180例轻度脑损伤患者的脑CT和脑MRI资料进行分析,根据有或无异常脑MRI表现将无阳性CT表现患者分为2组,对影像资料进行评价。结果无阳性CT表现的轻度脑损伤患者18例(10.0%)有颅脑损伤表现,最多见的症状为头痛(51.7%)。MRI显示颅脑损伤部位包括颞极区(n=8)、额极(n=5)、大脑镰(n=2)、基底节(n=1)、小脑幕(n=1)和外侧裂(n=1)。颅脑损伤多见于意识丧失、症状时间>2周或线性颅骨骨折患者(P=0.000 13)。结论轻度脑损伤无阳性CT表现患者少数可有颅脑损伤,提示即使经CT扫描无异常表现的轻度脑损伤患者亦需进一步检查,包括MRI扫描。Objective To observe the value of brain SWI on patients with mild brain injury with no positive CT.MethodsFrom January 2010 to December 2013,180 cases of mild brain injury in patients with brain CT and brain SWI data were analyzed.The presence or absence of abnormal brain MRI showing no positive CT performance of patients were divided into two groups and the image data were evaluated.Results Eighteen patients(10.0%)with mild brain injury without positive CT showed craniocerebral injury,the most common symptoms were headache(51.7%).MRI showed craniocerebral injury:temporal pole(n=8),frontal pole(n=5),brain sickle(n=2),basal ganglia(n=1),cerebellum(n=1)and lateral fissure(n=1).Craniocerebral injury was more common in patients with loss of consciousness,symptom time>2 weeks or linear skull fracture(P=0.000 13).ConclusionThis study shows that a small number of patients with mild brain injury without mild CT may have brain injury.These results suggest that even patients with mild brain injury without CT scan are required to undergo further examination,including MRI scans.
