Abstract： @@ 随着CT技术的迅速进展,CT已经成为医学影像检查中非常重要的组成部分,而静脉注射对比剂增强的CT检查,尤其是CTA的普及更是增加了静脉注射碘对比剂的应用.在很多医疗机构,CTA已基本代替了常规DSA检查,成为血管性病变诊断首选的影像检查手段,甚至被认为可作为影像诊断的金标准[1].然而在临床实践中,新的CT设备也带来了新的问题和挑战.虽然当前CT快速的扫描能力使进行对比增强CT扫描时常可以获得足够诊断的图像质量,但在非常短的扫描时间内确保得到靶部位最大程度的强化却成为一个很大的临床问题,这对精确确定靶部位扫描延迟时间提出了更高要求.笔者综述当前CT静脉注射碘对比剂的一些原则和策略.
