Diffusion-MRI in neurodegenerative disorders

Area of Science:

• Neuroimaging
• Radiology
• Neurology

Background:

• Brain abnormalities in diseases are increasingly understood through advanced imaging techniques.
• Diffusion Magnetic Resonance Imaging (dMRI) utilizes water molecule displacement as a sensitive contrast mechanism.
• dMRI provides detailed structural information valuable in clinical and research settings.

Purpose of the Study:

• To review the applications, findings, and challenges of dMRI in neurodegenerative disorders.
• To explore the potential of dMRI as an imaging biomarker for early disease detection and monitoring.
• To summarize current research and future directions for dMRI in understanding neurodegeneration.

Main Methods:

• Review of existing literature on diffusion-MRI applications in neurodegenerative diseases.
• Analysis of dMRI's role in characterizing microstructural changes and neurophysiological mechanisms.
• Exploration of dMRI's utility as a quantitative imaging biomarker.

Main Results:

• dMRI has demonstrated utility in understanding microstructural changes in various neurodegenerative conditions.
• Quantitative indices from dMRI can serve as potential imaging biomarkers for early detection and tracking of disease progression.
• The technique offers insights into the neurophysiological mechanisms underlying disorders like Alzheimer's, Parkinson's, and ALS.

Conclusions:

• Diffusion-MRI is a powerful tool for investigating neurodegenerative disorders.
• Its quantitative nature supports its use as an imaging biomarker for early detection and patient monitoring.
• Further research is needed to fully leverage dMRI's potential in clinical trials and patient management.
