Which is better for head injury CT scan or MRI?
A CT scan is the test of choice to evaluate for the four types of intracranial hemorrhage (subdural, epidural, intracerebral, or subarachnoid) bleeding in the brain, swelling of the brain during the first 24 to 48 hours after injury, or to detect a skull fracture because it is faster, more cost-effective, and easier to …
Which scan is best for head injury?

What will a brain MRI show that a CT wont?
Where MRI really excels is showing certain diseases that a CT scan cannot detect. Some cancers, such as prostate cancer, uterine cancer, and certain liver cancers, are pretty much invisible or very hard to detect on a CT scan. Metastases to the bone and brain also show up better on an MRI.
Does traumatic brain injury show up on MRI?
About 80 percent of TBIs cannot be seen on an MRI or CT scan. The only other way to discover a TBI used to be neuropsychological or psychological testing – a fancy way of saying doctors ask patients questions or give them tasks to complete.
Can CT scan show old brain injury?
Because microscopic injury to the brain may be a cause of problems, however, even MRI may not be able to detect any abnormality in a patient with TBI. Long after the injury, MRI as well as CT may demonstrate brain atrophy, which results when dead or injured brain tissue is reabsorbed following TBI.
Can a CT show brain lesions?
CT and MRI scans allow radiologists to identify the exact location of brain lesions. This enables us to see how they relate to the adjacent brain structures, often helping us to understand patients’ symptoms. CT and MRI scans also show different feature sets that can help determine the type of brain lesion.
Can a CT scan show brain damage?
X-rays, MRIs, and CT scans can detect fractures, hemorrhages, swelling, and certain kinds of tissue damage, but they do not always detect traumatic brain injury.

What is a normal brain CT scan?
CT scans, which use X-rays to detect brain structures, can show evidence of brain atrophy, strokes and ischemia, changes to the blood vessels, and other problems such as hydrocephalus and subdural hematomas. MRI scans use magnetic fields and focused radio waves to detect hydrogen atoms in tissues within the body.
