CT images of the head are used to investigate and diagnose brain injuries and other neurological conditions, as well as other conditions involving the skull or sinuses; it used to guide some brain surgery procedures as well. [2] CT scans expose the person getting them to ionizing radiation which has a risk of eventually causing cancer; some ...
CT Perfusion scan of the brain. CT perfusion imaging is a specific form of CT to assess flow through blood vessels whilst injecting a contrast agent. [21] Blood flow, blood transit time, and organ blood volume, can all be calculated with reasonable sensitivity and specificity. [21]

[1] [3] CT scan is the imaging modality of choice as it is widely available, quick, and with minimal risks. [1] However, CT scan can be limited in determining the exact cause of cerebral edema in which cases, CT angiography (CTA), MRI, or digital subtraction angiography (DSA) may be necessary. MRI is particularly useful as it can differentiate ...
The diagnosis is usually made by a brain scan , in which areas of swelling can be identified. The treatment for PRES is supportive: removal of the cause or causes and treatment of any of the complications, such as anticonvulsants for seizures. PRES may be complicated by intracranial hemorrhage, but this is relatively rare. The majority of ...
As the brain is encased in the skull, limited swelling can be accommodated until the brain is no longer able to maintain normal function. There are two potential negative consequences from this swelling: ischemia due to compression of the brain tissue resulting in lack of blood and oxygen, and herniation of the brain. [4]
X-ray CT scans take many X-ray measurements from different angles to produce virtual "slices" of specific areas of a scanned object that can then be reassembled into a complete image of the object. Such scans can detect tumors by the swelling and anatomical distortion they cause, or by surrounding edema .
The relative risk of post-traumatic seizures (PTS) increases with the severity of traumatic brain injury (TBI). [126] A CT of the head years after a traumatic brain injury showing an empty space where the damage occurred marked by the arrow. Improvement of neurological function usually occurs for two or more years after the trauma.
