Abstract:
Arterial spin labeling (ASL),unlike dynamic magnetic susceptibility contrast enhanced perfusion imaging,does not require contrast agents and it is a reusable and noninvasive imaging approach. This technique reverses the marker flow to the arterial blood protons of the brain and then uses its tracer to evaluate brain perfusion. If all la-beled blood arrive at the imaging voxel at the time of image acquisition,the signal difference between the marker image and the control image will be proportional to the cerebral blood flow. In recent years,with the development of ASL tech-nology,pediatric brain diseases such as ischemia and hypoxic encephalopathy,pediatric epilepsy,pediatric encephalitis and other diagnosis has made new progress.
