Serial evaluation of diffusion tensor brain fiber tracking in a patient with severe diffuse axonal injury.
نویسندگان
چکیده
Serial evaluation of diffusion tensor brain fiber tracking was performed in a 27-year-old female patient with diffuse axonal injury after a traffic accident. Although the result of brain fiber tracking was not necessarily parallel to her clinical symptoms, it may have predicted the neurologic prognosis.

Diffusion tensor tractography of traumatic diffuse axonal injury.
BACKGROUND Diffuse axonal injury is a common consequence of traumatic brain injury that frequently involves the parasagittal white matter, corpus callosum, and brainstem. OBJECTIVE To examine the potential of diffusion tensor tractography in detecting diffuse axonal injury at the acute stage of injury and predicting long-term functional outcome. DESIGN Tract-derived fiber variables were ana...
متن کاملDegeneration of cingulum and fornix in a patient with traumatic brain injury: diffuse tensor tractography study.
OBJECTIVES The cingulum and fornix are important structures for memory function. Using follow-up diffusion tensor tractography in a patient with traumatic brain injury we found degeneration of the cingulum and fornix. CASE REPORT An 18-year-old male who had had a traffic accident underwent conservative management for diffuse axonal injury. Brain magnetic resonance imaging showed an encephalom...
متن کاملClinical Utility of Diffusion Tensor Imaging and Fibre Tractography for Evaluating Diffuse Axonal Injury with Hemiparesis
Although diffuse axonal injury (DAI) frequently manifests as cognitive and/or motor disorders, abnormal brain findings are generally undetected by conventional imaging techniques. Here we report the case of a patient with DAI and hemiparesis. Although conventional MRI revealed no abnormalities, diffusion tensor imaging (DTI) and fibre tractography (FT) revealed the lesion speculated to be respo...
متن کاملNeurophysiological Study of Traumatic Brain Injury: To Slice or Not to Slice
One of the most critical neuropathological features of traumatic brain injury (TBI) is axotomy [1-5]. Even in mild (m) TBI, diffuse axotomy is easily and consistently observed as axons that end in swellings and dislocation from the distal part of the axon [6-8]. Integrity of axons can be measured in the clinical population with diffusion tensor imaging (DTI) [9-12]. Patient outcome has been cor...
متن کاملEvaluation for MTBI and DAI by using Voxel-Based Diffusion Tensor Imaging
Introduction: In Japan, there are approximately 280,000 new cases of traumatic brain injury (TBI) each year, with at least 80% being classified as mild. The diagnosis and management of mild traumatic brain injury (MTBI) continues to be the subject of debate, with varying opinions regarding the extent to which organically based impairments vs the impact of other stressors cause ongoing disabilit...
