Aquilion ONE能做啥？及其优势(系列之一)

1、Toshiba Medical Systems CorporationToshiba Medical Systems CorporationAquilion ONE能做啥？及其优势（系列之一） 葛冰Toshiba Medical Systems CorporationToshiba Medical Systems Corporation基本信息1：脑动脉瘤破裂伴蛛血发病率及死亡率高。2：320排动态容积CT扫描+心电门控，对破裂和未破裂的脑动脉瘤搏动异常隆起搏动异常隆起点点（即相关出血点责任部位）的监测，对于临床应用的意义重大。3：方法：容积扫描+心电门控。（full）全扫描重建，把一个心动周

2、期分成20个序列，观察。Toshiba Medical Systems CorporationToshiba Medical Systems Corporation基本信息破裂脑动脉瘤ruptured cerebral aneurysm 简称(RCA).处理方案：1：开颅夹闭（或者结扎）手术2：经血管栓塞两种方式各有利弊。如果能够监测到破裂出血点，有利于外科治疗方案的选择。Toshiba Medical Systems CorporationToshiba Medical Systems Corporation基本信息未破裂脑动脉瘤unruptured cerebral aneurysm 简称

3、(URCA).能够评估动脉瘤破裂的风险，对于病人的管理、随访监测和预后有极大好处。Toshiba Medical Systems CorporationToshiba Medical Systems Corporation（病例1）左颈内动脉瘤破裂伴蛛血（多发动脉瘤）Toshiba Medical Systems CorporationToshiba Medical Systems Corporation阳性的搏动异常隆起点搏动异常隆起点Toshiba Medical Systems CorporationToshiba Medical Systems Corporation搏动异常隆起点，搏
