Diffusion-weighted MRI can diagnose 'mad cow'-related disease in humans before symptoms show
...ers analyzed nine cases of CJD in which MRI of the brain
was performed during early, intermediate and late stages of the disease. At the early stage, researchers were able to detect the disease using diffusion-weighted MRI in all cases. Diffusion-weighted MRI follows the random motion of water molecules th...
Nanoscale diagnostic sets sights on Alzheimer's
