Abstract

Purpose: To analyze white matter pathologic abnormalities by using diffusion-tensor (DT) imaging in a multicenter prospective cohort of comatose patients following cardiac arrest or traumatic brain injury (TBI). Materials and Methods: Institutional review board approval and informed consent from proxies and control subjects were obtained. DT imaging was performed 5-57 days after insult in 49 cardiac arrest and 40 TBI patients. To control for DT imaging-processing variability, patients' values were normalized to those of 111 control subjects. Automated segmentation software calculated normalized axial diffusivity (λ1) and radial diffusivity (λ ) in 19 predefined white matter regions of interest (ROIs). DT imaging variables were compared by using general linear modeling, and sidetoside Pearson correlation coefficients were calculated. P values were corrected for multiple testing (Bonferroni). Results: In central white matter, λ1 differed from that in control subjects in six of seven TBI ROIs and five of seven cardiac arrest ROIs (all P ⊤ differed from that in control subjects in all ROIs in both patient groups (P 1 was decreased compared with that in control subjects in three of 12 TBI ROIs (P ⊤ was increased in all TBI ROIs (P 1was lower in cardiac arrest than in TBI in six of 12 ROIs (P ⊤ was higher in TBI than in cardiac arrest in eight of 12 ROIs (P
