ALS scan pics can reveal various changes in the brain and spinal cord, including: als scan pic
In clinical practice, an “ALS scan” usually means . There is no single diagnostic scan for ALS (it’s a clinical diagnosis), but imaging helps exclude mimics (e.g., cervical myelopathy, multiple sclerosis, tumor) and may show supportive features . including: In clinical practice
