Diffuse axonal injuries: pathophysiology and imaging

Neuroimaging Clinics of North America, 2002
Diffuse axonal shear injury is a common traumatic brain injury, with significant neurologic and behavioral impact on patients. Radiologic recognition of this entity and understanding of its sequelae can be of utmost importance in the prediction of outcome and planning for rehabilitation.

Challenges of Diffuse Axonal Injury Diagnosis

Rehabilitation Nursing, 2009
"This can't be right. Jay is in a vegetative state following a severe traumatic brain injury (TBI), but his computed tomography scan is essentially normal. How am I going to explain this to his mom?" This is a conversation I overhear among my rehabilitation nurse colleagues from time to time. Jay has a type of brain trauma called diffuse axonal injury (

Longitudinal changes in brain volumetry and cognitive functions after moderate and severe diffuse axonal injury

Brain Injury, 2018
Background and objective: Diffuse axonal injury (DAI) induces a long-term process of brain atrophy and cognitive deficits. The goal of this study was to determine whether there are correlations between brain volume loss, microhaemorrhage load (MHL) and ...

Diffuse axonal injury in adults

Trauma, 2003
Diffuse axonal injury is a frequent component of traumatic brain injury that contributes significantly to morbidity and mortality. It encompasses a spectrum of injury from mild concussion to deep coma and death. There have been advances in our understanding of the pathophysiological processes that occur after diffuse axonal injury and ionic ...

DIFFUSE AXONAL INJURY IN HEAD INJURIES CAUSED BY A FALL

The Lancet, 1984
82 cases of diffuse axonal injury were found at necropsy in 635 patients with fatal nonmissile head injuries. 13 of these injuries were attributable to falls, and in all the patients fell from a considerable height. Diffuse axonal injury was not found in those with head injuries caused by a simple fall--ie, a fall from not more than the person's own ...

Diffusion-weighted MRI in diffuse axonal injury of the brain

European Radiology, 2002
The goal of this study was to identify and describe the different types and patterns of tissue injury which are encountered by diffusion-weighted imaging (DWI) in diffuse axonal injury (DAI) of the brain. The DWI data sets of 98 patients who suffered from a closed-head injury were retrospectively evaluated. Medical records were reviewed to rule out pre-

Microstructural and Neurochemical Changes in the Rat Brain After Diffuse Axonal Injury

Journal of Magnetic Resonance Imaging, 2018
Diffuse axonal injury (DAI) is one of the devastating types of traumatic brain injury, but is difficult to detect on conventional imaging in its early stages.

MRI of diffuse axonal injury

1995
We reviewed spin-echo MRI of 53 patients with diffuse axonal injury (DAI). Initial MRI was obtained with 0.5-1.5 T systems within 7 days of injury. T2-hyperintense areas with or without haemorrhagic foci were found in 51 patients. The sites of lesions demonstrated on MRI were as follows: corpus callosum in 48 patients (mostly in body and splenium ...

Microscopic Diffuse Axonal Injury in Cases of Head Injury

Medicine, Science and the Law, 1985
Diffuse axonal injury is one of the most important types of brain damage that can occur in the course of a head injury. Its presence can usually be predicted post-mortem because of the presence of focal macroscopic abnormalities in the corpus callosum and in the brain stem. This report describes nine cases where the diagnosis could only be made on the

Axonal injury in the optic nerve: a model simulating diffuse axonal injury in the brain

Journal of Neurosurgery, 1989
✓ A new model of traumatic axonal injury has been developed by causing a single, rapid, controlled elongation (tensile strain) in the optic nerve of the albino guinea pig. Electron microscopy demonstrates axonal swelling, axolemmal blebs, and accumulation of organelles identical to those seen in human and experimental brain injury.
