Diffusion tensor imaging (DTI) images nerve fiber pathways by detecting:
A)the directional movement of water molecules.
B)different signal intensities between white blood cells and red blood cells.
C)differences in blood oxygenation.
D)changes in regional cerebral blood flow.

Question

Quizplus · Accepted Answer

DTI measures the directional movement of water molecules, which is influenced by the orientation of nerve fibers, allowing for the imaging of nerve fiber pathways.
