WebDec 3, 2024 · 1 Introduction. Diffuse axonal injury (DAI) is thought to be caused by shearing forces, but far from a proven disease, impulse and momentum fluid waves and other factors are currently being explored. Pathologically, DAI encompasses a spectrum of effects from primary mechanical breaking of the axonal cytoskeleton, to transport … WebOct 27, 2015 · to diffuse axonal injury. Diffuse axonal injuries are characteristic of head acceleration occurring gradually over a lengthy time period.19 Furthermore head motion in the coronal plane was found to be more damaging leading to severe axonal damage rather than the sagittal motion that produced mild or at most moderate damage to axons.20,21

WebMar 8, 2024 · Diffuse axonal injury is the result of shearing forces, typically from rotational acceleration (most often a deceleration). Due to the slightly different specific gravities (relative mass per unit volume) of white and grey matter, shearing due to change in velocity has a predilection for axons at the grey-white matter junction. WebDiffuse axonal injury is the tearing of the brain's long connecting nerve fibers (axons) that happens when the brain is injured as it shifts and rotates inside the bony skull. DAI usually causes coma and injury to many different parts of the brain. The changes in the brain are often microscopic and may not be evident on computed tomography (CT ...
WebAbstract. 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.

WebDiffuse axonal injury (DAI) can be defined as widespread traumatic injury to axons in the cerebral cortex, corpus callosum, and brainstem. It is the leading cause of morbidity and mortality in patients with traumatic brain injury. With rapid acceleration–deceleration of the head, shearing forces cause mechanical axonal damage.
