1、64层螺旋CT头颈血管造影在脑分水岭梗死中的应用胡学林1余东2(1四川省峨边彝族自治县人民医院放射科614300)(2四川省乐山市人民医院放射科614000)【摘要】目的：探讨64层螺旋CT头颈血管造影在脑分水岭梗死中的应用。方法：回顾性分析2012年11月-2013年9只入住我院神经内科的58例脑分水岭梗死患者的临床资料，观察组为皮质脑分水岭梗死，对照组为皮质下脑分水岭梗死，均釆用64层螺旋CT头颈血管造影的方法，以DSA及手术结果为金标准，比较两组患者的诊断正确率，颈内动脉狭窄的检出率和发生率，影像学特点。结果：
2、观察组诊断正确率100%,对照组为100%,两组间差异无统计学意义(P>；0.05)；观察组颈内动脉狭窄的检出率和发生率均小于对照组，差异有统计学意义(P<0.05)；观察组病灶形态、颅内血管异常等方面较对照组均有统计学意义(P<0.01)o结论：64层螺旋CT头颈血管造影在脑分水岭梗死中诊断率高，是一种安全、简便、可行的诊断技术，有积极的临床意义。【关键词】64层螺旋CT头颈血管造影脑分水岭梗死【中图分类号】R445【文献标识码】A【文章编号】2095-1752(2013)36-0062-02App
