Question

Quizplus · Accepted Answer

DTI (Diffusion Tensor Imaging) is the most appropriate method for assessing the rate and direction of water diffusing through white matter, which can provide information about the microstructural integrity of white matter, including fiber direction, density, and coherence. fMRI (functional Magnetic Resonance Imaging) and MRI (Magnetic Resonance Imaging) can provide information about brain structure and function, but they cannot directly assess the diffusion of water in white matter. A MRI scanner is a machine used to perform MRI scans, it is not a method itself.
