Fibre tracking in patients with persistent vegetative state

Objective: The diagnosis of persistent vegetative state is still limited to the clinical examination. Imaging techniques do not play a role in securing the diagnosis and or the probability of repair. Using fibre tracking (FT), it was tried to visualize and quantify the defect areas. Methods: Seven patients in a persistent vegetative state after cerebral trauma were examined in a 1.5-T MRI device (INTERA, Philips Co) with coronal diffusion-weighted spin echo sequences. MRI was performed after a mean of 6 months following cerebral trauma. Six non-colinear gradient impulses were used along the corticospinal fiber t…
