Abstract：The liver is supplied with blood by portal vein and hepatic artery. Different types of lesions in the liver have different
blood supply, contrast agent arrival time and residence time. The advent of rapid spiral of CT and its associated high-pressure syringe
has enabled scanning to completely differentiate among the arterial, venous, and equilibrium phases. It plays a significant role in the
differential diagnosis of liver tumors and inflammation, blood perfusion and vascular imaging, which has been widely used in clinical
practice. This article reviewed the current situation and existing problems of the anatomical pathophysiological basis and multi-phase
scanning time window of dynamic contrast-enhanced CT examination of children’s liver.
