There are several types of MRI scans, including structural, functional, and diffusion tensor imaging. Structural MRI scans provide high-resolution images that can be used to visualize the brain's anatomy, while functional MRI scans measure blood flow in the brain to identify areas of activity. Diffusion tensor imaging (DTI) is a type of magnetic resonance imaging technique that measures water molecule movement within the brain. This helps to reveal the white matter tracts connecting various regions of the brain, which can help with understanding how the brain functions.
