Application of Multi-probe PET/MR Imaging in the Diagnosis and Evaluation of Alzheimer's Disease

February 13, 2023 updated by: Xiaoli Lan, Wuhan Union Hospital, China
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.

Detailed 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.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
AD group
Patients who meet the core clinical diagnostic criteria for Alzheimer's disease as defined by NIA-AA for mild cognitive decline or probable Alzheimer's disease.
18F-FDG, 11C-PIB and 18F-PM-PBB3 injection are radiopharmaceuticals used for positron emission tomography (PET) imaging. 18F-FDG dose is about 3.7-5.4 MBq/kg (0.1 -0.15 mCi/kg), and used in the assessment of brain glucose metabolism. 11C-PIB dose is about 5-10mCi, and used in the assessment of amyloid deposition. 18F-PM-PBB3 dose is about 5-10mCi, and used in the assessment of tau deposition. Use PET/MR equipment for simultaneous PET and MR collection.
Other Names:
  • Positron Emission Tomography/Magnetic Resonance
Healthy control group
Age-matched subjects, who are healthy and have no clinically significant related abnormalities in their physical examinations, laboratory tests, vital signs, or ECG. In addition, no first-degree family history of early-onset AD or other neurodegenerative diseases related to dementia.
