Revolution CT采集参数
结论 曝光时间小于2秒，射线剂量小于1 mSv 的情况下，Revolution CT即可完成高清头颈CT血管造影。（图1）。 This head and neck angiography was performed in less than two seconds with high-resolution images at less than one milliSievert.  图1: 高清头颈CT血管造影
Laurent Macron医生的评价
“Revolution CT快速的头颈血管造影能得到纯净的动脉期图像，而无静脉污染。精确的影像学检查确保了可靠的临床诊断。” With Revolution CT, faster head and neck angiography allows for uniform contrast in pure arterial phase, with no venous contamination. Therefore, it gives us the image accuracy that we need to provide a confident diagnosis to referring clinicians.
