Diffusion tensor MR imaging in diffuse axonal injury.
BACKGROUND AND PURPOSE Disruption of the cytoskeletal network and axonal membranes characterizes diffuse axonal injury (DAI) in the first few hours after traumatic brain injury. Histologic abnormalities seen in DAI hypothetically decrease the diffusion along axons and increase the diffusion in directions perpendicular to them. DAI therefore is hypothetically associated in the short term with de...
متن کاملProton MR spectroscopic imaging depicts diffuse axonal injury in children with traumatic brain injury.
BACKGROUND AND PURPOSE Diffuse axonal injury (DAI) after traumatic brain injury (TBI) is important in patient assessment and prognosis, yet they are underestimated with conventional imaging techniques. We used MR spectroscopic imaging (MRSI) to detect DAI and determine whether metabolite ratios are accurate in predicting long-term outcomes and to examine regional differences in injury between c...
متن کاملAssociation Between Serum Electrolyte Disturbances and Glasgow Coma Scale Score in Patients With Diffuse Axonal Injury
Background: Appropriate clinical measures to prevent secondary brain damage in traumatic brain injury are of critical importance. Objectives: This study aims to investigate the relationships between serum electrolyte disturbances and Glasgow Coma Scale (GCS) score in patients with Diffuse Axonal Injury (DAI) at the time of admission and discharge. Materials & Methods: In this retrospective cr...
متن کاملDiffusion tensor imaging as potential biomarker of white matter injury in diffuse axonal injury.
BACKGROUND AND PURPOSE Multiple biomarkers are used to quantify the severity of traumatic brain injury (TBI) and to predict outcome. Few are satisfactory. CT and conventional MR imaging underestimate injury and correlate poorly with outcome. New MR imaging techniques, including diffusion tensor imaging (DTI), can provide information about brain ultrastructure by quantifying isotropic and anisot...
متن کاملDiffuse Axonal Injury in Head Trauma
Background: Diffuse axonal injury (DAI) is one of the most common and important pathologic features of traumatic brain injury (TBI). The susceptibility of axons to mechanical injury appears to be due to both their viscoelastic properties and their high organization in white matter tracts. Although axons are supple under normal conditions, they become brittle when exposed to rapid deformations a...
