Brain CT (left) showing subarachnoid hemorrhage at onset and diffusion tensor tractography of the ascending reticular activating system between the pontine reticular formation and the intralaminar thalamic nuclei (right) in 2 patients (A, A 69-year-old woman, Glasgow Coma Scale score, 11; and B, A 57-year-old woman, Glasgow Coma Scale score, 15).
- Fig 2.
Correlation between the Glasgow Coma Scale score and fractional anisotropy (A), apparent diffusion coefficient (B), and tract number (C) of patients with subarachnoid hemorrhage on the more affected side, the less affected side, and both sides.
