Drug addiction is one of the most serious public health problems in the world. At present, drug addiction is considered as a chronic and recurrent brain disease. The exact mechanism of drug addiction has not been fully elucidated. The development of peddler imaging technology and the synthesis of various imaging agents have provided great help for people to understand the neuropharmacological mechanism of drug addiction. This paper reviews the application of positron emission tomography (PET) imaging in the study of drug addiction mechanism, focusing on the monitoring of neurotransmitter receptors, receptor transporters, regional cerebral blood flow and cerebral glucose metabolism in the process of drug addiction by using PET in vivo imaging technology, so as to understand the neurobiological basis of drug addiction and provide theoretical basis for effective treatment measures.
