Traumatic brain injury; Other names: Intracranial injury, physically induced brain injury [1] CT scan showing cerebral contusions, hemorrhage within the hemispheres, and subdural hematoma. There is also displaced skull fracture of left transverse parietal and temporal bones. [2] Specialty: Neurosurgery, pediatrics: Symptoms
However, coronal images require the person to hyperextend their neck, which must be avoided if any possibility of neck injury exists. [8] CT scans of the head increase the risk of brain cancer, especially for children. As of 2018, it appeared that there was a risk of one excess cancer per 3,000–10,000 head CT exams in children under the age ...
Diffuse injury has more microscopic injury than macroscopic injury and is difficult to detect with CT and MRI, but its presence can be inferred when small bleeds are visible in the corpus callosum or the cerebral cortex. [34] MRI is more useful than CT for detecting characteristics of diffuse axonal injury in the subacute and chronic time ...
CT scans can show brain bleeds, fractures of the skull, fluid build up in the brain that will lead to increased cranial pressure. [ 36 ] MRI is able to better to detect smaller injuries, detect damage within the brain, diffuse axonal injury, injuries to the brainstem, posterior fossa, and subtemporal and subfrontal regions.
A type of diffuse brain injury, multiple petechial hemorrhages are not always visible using current imaging techniques like CT and MRI scans. This may be the case even if the injury is quite severe, though these may show up days after the injury. [15] Hemorrhages may be larger than in normal contusions if the injury is quite severe.
The study looked at 353 patients who, from the outside, seemed to have lost consciousness due to a brain injury. The sources of these injuries varied from accidents to heart attacks and strokes.
For spontaneous intracerebral hemorrhage seen on CT scan, the death rate is 34–50% by 30 days after the injury, [22] and half of the deaths occur in the first 2 days. [51] Even though the majority of deaths occur in the first few days after ICH, survivors have a long-term excess mortality rate of 27% compared to the general population. [ 52 ]
