This study was focused on the U-fibers located on the Superficial White Matter (SWM) of the Rhesus macaque brain.
A diffusion MRI (dMRI) pulse-sequence with a 3D multi-shot-EPI module was used to achieve a 0.5 mm isotropic dMRI data in 4 macaques.
The organization of white matter in the region of arcuate sulcus (AS) was analyzed using diffusion tensor and fiber orientation distribution data, the U-fiber over all the AS was tracked and its water diffusion metrics were quantitatively assessed.
The results, obtained using high-resolution dMRI, pave the way for quantitative analyses of SWM for clinical and neuroscientific applications.
