For years, the primary role of a scan in the ALS diagnostic journey was to rule out "ALS mimics" like spinal tumors or herniated disks. However, recent breakthroughs in neuroimaging are shifting this paradigm: PubMed Central (PMC) (.gov) High-Resolution MRI
: These functional imaging tools use radiotracers to target specific biochemical pathways, helping to stage the disease even before major motor symptoms appear. Texture Analysis

When sorting through free image repositories, look for specific visual cues to find the highest value image for your project: Feature / Metric What Makes It "Better" Clinical Significance T2-Weighted or FLAIR MRI
Collections are increasingly formatted for machine learning applications, including labeled and annotated images. For years, the primary role of a scan

Traditional scanning methods often rely on expensive and proprietary software, which can be a significant barrier for individuals and organizations on a tight budget. Moreover, these methods may not always produce the desired level of accuracy and clarity, leading to subpar results.
