Dti mri tractography
WebDec 2, 2024 · Diffusion tensor imaging with fiber tractography is a powerful functional MRI technique that can detect the microstructural changes and integrity of the white matter tracts in patients with acute cerebrovascular stroke; thus, it can predict the clinical outcome and can guide the rehabilitation strategy. WebDTI variables were not associated with allocation of placebo or thyroid supplementation. Markers of poorly organised brain microstructure were associated with low plasma FT4 concentrations after birth. The findings suggest that plasma FT4 concentrations affect brain development in very immature infa …
