摘要
目的:探讨分析数字减影CT血管成像在蛛网膜下腔出血诊断中的价值。方法选取2010年1月~2013年1月在我院接受诊断和治疗的70例蛛网膜下腔出血患者作为研究对象,使用GE生产的16层螺旋CT进行检测,扫描参数设置为电压120kV,电流250~300mA,旋转速度0.4s,FOV 20~25cm,矩阵512X512,扫描层厚为5mm。分别进行CT血管成像和数字减影CT血管成像,对比分析两种方法的检测结果。结果70例患者使用DSA成像检出91个动脉瘤,CT血管成像检出72个,漏检19个位于ICA海绵窦段;CT血管成像和DSA成像在动脉瘤和图像质量方面差异不明显,>0.05,不具有统计学意义。结论 DSA准确率较高,临床实践应该结合具体情况综合各方面因素进行合理选择。
Objective To explore the value of digital subtraction CT angiography in the diagnosis of subarachnoid hemorrhage.Methods Selected our hospital 70 cases diagnosed and treated of subarachnoid hemorrhage in January 2010-January 2013,used 16-slice CT detected by GE manufactured,respectively took angiography CT and digital subtraction angiography CT,comparative analyzed of the two test results.Results CT angiography and DSA imaging were not significantly dif erent in aneurysm and image quality,>0.05,had no significant dif erence.Conclusion DSA had higher accuracy rate,in clinical practice should be combined with the specific various factors to make the reasonable choices.
