简要总结
Conclusions In conclusion, the timing information of the bolus tracking of previous carotid CT angiography can be used in the stroke protocol to reduce radiation exposure by avoiding unnecessary scans. In addition, the information from bolus tracking allows for the better timing of CTP, which could lead to better outcomes in certain cases by adjusted timing.
