Research Progress in Evaluating Neurovascular Coupling Function by Magnetic Resonance Imaging
Neurovascular coupling reflects the close relationship between neuronal activity in the brain and cerebral blood flow,which provides a new perspective for the occurrence and development of central nervous imaging.However,neurovascular coupling can be applied clinically mainly through transcranial Doppler ultrasound,single photon emission tomography and xenon scavenging technology.The inability of these technologies to better understand the pathologic mechanisms of diseases limits their application to a large extent.Compared with the above techniques,magnetic resonance imaging has higher soft tissue resolution,no radiation and other advantages,so in recent years,magnetic resonance imaging has been widely used in the detection of neurovascular coupling.A great deal of practical work has been carried out on the study of neurovascular coupling function,and new progress has been made.In this paper,these magnetic resonance imaging techniques are described to provide a new understanding for researchers.
