Clinical Trial Summary

Alzheimer's disease (AD) is the most common cause of cognitive impairment, and its diagnosis requires a comprehensive analysis of the results of medical history, neuropsychological evaluation, imaging and laboratory tests. Among them, it has been widely recognized that amyloid PET imaging is used in the early diagnosis of AD, tau protein PET imaging is used in the assessment of the progression of AD, and the glucose metabolism PET imaging is used in the assessment of nerve damage. MRI can provide structure, blood perfusion, neural network connection damage and other information through multi-sequence scans. With the help of the PET/MR multi-modal imaging platform and multi-probe imaging technology, it can provide more sensitive and accurate imaging information for early diagnosis and disease assessment of AD, and provide a basis for clinical treatment decision-making.

Clinical Trial Description

Cognitive impairment is a common neurodegenerative disease. The incidence of Alzheimer's disease (AD) in people over 65 years old is close to 5%, which brings a heavy burden to society. Relying only on medical history and neuropsychological evaluation, the early diagnosis and differential diagnosis of AD are difficult, and further imaging and laboratory tests are needed. This project will use PET/MRI, the most advanced imaging platform, to design a prospective clinical research program, combined with multi-sequence MRI and multi-probe PET imaging, to evaluate suspected or diagnosed AD patients. Through multi-parameter analysis of the structure MRI, function MRI (3D ASL, BOLD, DTI), metabolism PET (18F-FDG) , Aβ (11C-PIB) and tau (18F-PM-PBB3) PET, combined with clinical information, to evaluate the value of multi-modal imaging for early diagnosis and differential diagnosis of AD, to assist the clinic in the adjustment of early intervention measures and treatment strategies. ;
