Normal brain and brain tumor: Multicomponent apparent diffusion coefficient line scan imaging

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 de cay fits produced two apparent diffusion constants and respective signal am plitudes. Images based on these parameters show potential for use in the di fferentiation of gray and white matter, edema, and tumor.
