目的：对脑动脉瘤破裂的CT影像特点进行探析。方法收集临床资料是2013年1月~2015年6月我院治疗的21例脑动脉瘤破裂患者,患者均进行CT检查,5例患者进行DSA检查,少数患者进行MRI、MRA等检查。结果 CT检查中,19例确诊的脑动脉瘤患者均发现存在脑动脉瘤破裂,并经临床证实,诊断准确率为90.5%。结论脑动脉破裂使用CT进行检查,能够准确显示脑动脉瘤破裂的影像特点,有利于脑动脉瘤破裂的临床诊断。“,”Objective To analyze CT image of brain aneurysm rupture.Methods Clinical data were collected in January 2013 to June 2015,the hospital treatment of 21 patients with brain aneurysm rupture,patients were performed CT examination,5 cases with DSA examination,a few patients with MRI,MRA,etc.Results CT examination,19 patients with diagnosis of cerebral aneurysms were found to have brain aneurysm rupture,and confirmed by clinical and diagnostic accuracy was 90.5%.Conclusion Cerebral artery rupture using CT inspection,to be able to accurately display imaging characteristics of cerebral aneurysm rupture,is helpful for clinical diagnosis of cerebral aneurysms.
