What measurement is obtained in studies using diffusion tensor imaging?
A) Fractional anisotropy
B) BOLD
C) Voltage
D) Grey-matter density

Question

Quizplus · Accepted Answer

Diffusion tensor imaging measures the direction and intensity of water molecules in brain tissue, which can reveal the location and orientation of white matter pathways. Fractional anisotropy (FA) is a commonly used measurement that reflects the degree of diffusion directionality within a voxel of brain tissue. Therefore, A is the correct choice as it represents the measurement obtained in studies using diffusion tensor imaging.
