Application advances of PET/MR in neurodegenerative diseases

Neurodegenerative diseases endanger people′s physical and mental health. PET/MR can acquire PET and MR images simultaneously, thus avoid interference of external stimuli and spatial difference in different time, and significantly improve image accuracy. PET/MR displays an important value in the pathogenesis, early diagnosis and differential diagnosis of neurodegenerative diseases. This article reviews the application value and research progress of PET/MR in important neurodegenerative diseases, such as Alzheimer′s disease (AD) and Parkinson′s disease (PD).
