Sentences with phrase «measure white matter integrity»

To measure white matter integrity, researchers used fractional anisotropy (FA), obtained by diffusion tensor imaging (DTI).

«We're measuring such variables as prefrontal cortex volume and white matter integrity.

For the new study, researchers from the University of Pittsburgh Medical Center (UPMC) in Pittsburgh used diffusion tensor imaging (DTI), an MRI technique that measures the integrity of white matter — the brain's signal - transmitting nerve fibers — to see if injuries to the nerves may be the root cause of these post-traumatic depression and anxiety symptoms.

Compared to controls, patients with depression had decreased fractional anisotropy (FA), a measure of the structural integrity of white matter connections, around an area near the deep gray matter of the brain that is strongly associated with the brain's reward circuit.

«It was illuminating to see the association between measures of white matter integrity and important outcomes occurring months to years down the road in our study population.»

«We retrospectively analyzed the data from the DTI sequence to derive measures of white matter integrity, which we compared to clinical measures and subsequent outcome measures 6 months to 2.5 years after the initial evaluation.»

Here the authors try combining probing white matter integrity with a MRI measure of whether the brain has shrunk as a result of disease.

The aims of the study are 1) to investigate differences in the topographic distribution of white matter integrity between adolescents with IAD and healthy controls without IAD, making no a priori assumptions about the location of possible abnormalities, and 2) to determine whether there was any relationship between white matter integrity and neurophysiological measures in IAD subjects.
