Differences between relapsing-remitting and chronic progressive multiple sclerosis as determined with quantitative MR imaging.

abstract：:Magnetic resonance line scan diffusion imaging of the brain, with diffusion weighting between 5 and 5,000 sec/mm(2), was performed in healthy subjects and patients with a 1.5-T machine. For each voxel, biexponential signal decay fits produced two apparent diffusion constants and respective signal amplitudes. Images ba...
