Abstract:
Atrophy measured on structural magnetic resonance imaging (sMRI) is a powerful biomarker of the stage and intensity of the neurodegenerative aspect of Alzheimer's disease (AD) pathology. In this review, we will discuss the role of sMRI as an AD biomarker by summarizing (a) the most commonly used methods to extract information from sMRI images, (b) the different roles in which sMRI can be used as an AD biomarker, and (c) comparisons of sMRI with other major AD biomarkers.
Insights
Structural MRI (sMRI) effectively measures brain atrophy, indicating Alzheimer's disease (AD) progression. This review covers sMRI methods, its biomarker roles, and comparisons with other AD diagnostic tools.
Area of Science:
- Neuroimaging
- Neurology
- Biomarker Research
Background:
- Alzheimer's disease (AD) is characterized by neurodegeneration.
- Brain atrophy on structural magnetic resonance imaging (sMRI) is a key indicator of AD pathology stage and severity.
Purpose of the Study:
- To review the utility of sMRI as a biomarker for Alzheimer's disease.
- To summarize methods for extracting information from sMRI.
- To compare sMRI with other AD biomarkers.
Main Methods:
- Literature review of studies utilizing sMRI for Alzheimer's disease assessment.
- Analysis of common image processing techniques for sMRI data.
- Comparative evaluation of sMRI against other established AD biomarkers.
Main Results:
- sMRI provides quantitative measures of brain atrophy.
- Various methods exist to extract meaningful data from sMRI scans.
- sMRI plays diverse roles in diagnosing and staging AD.
- sMRI shows promise when compared to other biomarkers.
Conclusions:
- Structural MRI is a valuable tool for assessing neurodegeneration in Alzheimer's disease.
- Understanding sMRI analysis methods enhances its clinical application.
- sMRI offers complementary information to other AD diagnostic markers.
