CT与磁共振成像检查诊断颅脑外伤的价值分析

Value of CT and Magnetic Resonance Imaging in the Diagnosis of Craniocerebral Trauma

目的对比CT与磁共振成像检查在颅脑外伤诊断中的应用价值。方法选取2017年9月至2018年6月于我院进行检查的颅脑外伤患者80例,所有患者入院后均给予CT检查,待病情稳定后行MRI检查。比较两种检查方法在弥漫性轴索损伤阳性率及病灶检出情况。结果MRI对蛛网膜下腔出血、弥漫性脑肿胀及非出血性病灶的阳性检出率均明显高于CT(P<0.05)。MRI的病灶检出数量明显高于CT(P<0.05)。结论MRI和CT均可诊断颅脑外伤,但MRI的适用范围更广,病灶检出率较高,对于颅脑外伤较为严重的患者可进行MRI检查,利于提高确诊率;对于其他类型的颅脑外伤患者,可根据患者病情选择诊断方法。

Objective To compare the application value of CT and magnetic resonance imaging(MRI)in the diagnosis of craniocerebral trauma.Methods 80 patients with craniocerebral trauma examined in our hospital from September 2017 to June 2018 were selected and given CT examinations after admission.MRI were performed after the condition was stable.The positive rate and lesion detection were compared between the two methods.Results The positive detection rates of MRI for subarachnoid hemorrhage,diffuse brain swelling and non-hemorrhagic lesions were higher than those of CT(P<0.05).The lesion detection numbers of MRI were significantly higher than those of CT(P<0.05).Conclusions Both MRI and CT can diagnose craniocerebral trauma,but MRI has wider application range and higher detection rate of lesions.For patients with more severe craniocerebral trauma,MRI can be performed to improve the diagnosis rate.For other types of craniocerebral trauma,the diagnosis method can be selected according to patients'disease condition.
