While "als scan free pics better" is likely a typo for "ALS (Amyotrophic Lateral Sclerosis) scans for free pics," it touches on a critical area of medical research: how modern imaging techniques are improving the diagnosis and monitoring of this progressive disease.

Early Detection: Advanced scans can now detect distinct brain atrophy patterns up to six years before clinical symptoms appear, particularly in individuals with genetic variants like C9orf72.

• Open-i (Open Access Biomedical Image Search): A service of the National Library of Medicine. It indexes over 3.7 million images from peer-reviewed journals. Search "ALS corticospinal tract MRI" for clinical-grade scans.
• Radiopaedia.org: While mainly for radiologists, its non-commercial Creative Commons (CC) section offers exceptional MRI and DTI (Diffusion Tensor Imaging) scans showing white matter degeneration in ALS patients.

Detect Early Changes: Identify distinct brain shrinkage or metabolic patterns up to six years before symptoms manifest.
