Question

Quizplus · Accepted Answer

Functional magnetic resonance imaging (fMRI) measures brain activity by detecting changes associated with blood flow, specifically related to blood oxygenation levels. Diffusion tensor imaging (DTI) is a type of MRI technique that maps the diffusion process of water molecules in biological tissues, primarily used to visualize white matter tracts in the brain.
