目的 探讨脑外伤诊断中磁敏感加权成像和颅脑CT的应用效果。方法 选取2015年1月到2015年12月间，于我院选择 200例脑外伤患者作为研究对象，所有患者均进行颅脑CT检查及磁敏感加权成像检查，统计两种检测方法对脑外伤 病灶检查结果及影像学检测状况，对比颅脑CT检查及磁敏感加权成像的检测结果。结果 采取SWI检查诊断准确率 97.0%（225/232）与CT检查90.5%（210/232）相比明显较高，P＜0.05。结论 与颅脑CT相比，磁敏感加权成像能提 高患者诊断效果，且成像清晰，可辅助临床诊断患者病灶严重程度，可在脑外伤患者诊断中推广运用。

Objective To investigate the diagnosis of traumatic brain injury in susceptibility weighted imaging and brain CT. Methods from January 2015 to December 2015, 200 cases of traumatic brain injury patients as the research object in our hospital, all patients underwent brain CT examination and susceptibility weighted imaging, detection of two kinds of methods for the detection of brain statistics results traumatic lesions and imaging findings, detection results of craniacerebral CT and susceptibility weighted imaging. Results SWI diagnostic accuracy rate of 97% (225/232) 90.5% and CT (210/232) is significantly higher, P<0.05. Conclusion Compared with brain CT, susceptibility weighted imaging can improve the effect of patients with diagnosis. And clear imaging, can assist the clinical diagnosis of patients with lesion severity, can be applied in the diagnosis of traumatic brain injury patients.
