Roll is conducting a research study. She wants to measure the physical connectivity in the research participants' brains by imaging their white matter. Which of the following methods will she use?
A) diffusion tensor imaging (DTI)
B) MRI spectroscopy
C) functional magnetic resonance imaging (fMRI)
D) computed tomography (CT)

Question

Quizplus · Accepted Answer

DTI is a specific type of MRI that is used to measure the diffusion of water molecules in the brain's white matter. This method provides information on the microstructure and physical connectivity of the brain's white matter. MRI spectroscopy is used to measure the chemical composition of the brain, fMRI measures changes in blood flow in response to neural activity, and CT uses X-rays to produce detailed images of internal structures of the brain but doesn't provide information on white matter connectivity.
