Can MRI show an old brain injury?

MRI can show brain atrophy long after the injury, which occurs when injured or dead brain tissue is resorbed after brain injury. Because injured brain tissue may not fully recover after a traumatic brain injury, doctors can detect TBI-related changes many years after an injury. However, diagnosing brain injuries can be complicated. About 80 percent of TBIs cannot be seen on an MRI or CT scan.

The only other way to discover a traumatic brain injury used to be neuropsychological or psychological testing, a fancy way of saying that doctors ask patients questions or give them tasks to complete. So what can an MRI see? An MRI can see subarachnoid hemorrhages, hemorrhages in the brain, old parts of brain damage where parts of the brain basically form scars. That will show up on an MRI often. But if it's at the smallest level, which is called Axonify shear, most of the time that won't show.

And we're talking about mild, moderate, and severe brain injuries. I have had clients who have very serious brain injuries that can return to a fairly normal life, and I have had clients with mild brain injuries who really have difficulty integrating into their daily lives because their symptoms are so significant. A CT scan takes pictures to create pictures of the brain. The scan can show if there is a fracture or bleeding.

An MRI creates clear images of brain tissue. Simple X-rays don't tell anyone much about the brain, and even a CT scan may look normal even if a brain injury has occurred. An electroencephalogram performed early may have shown the impact the collision had on your grandson's brain. An MRI of your head with sequences of images of the diffusion tensor may show some evidence of an old injury.

If your grandchild had any of the symptoms listed, talk to your pediatrician about the possibility that he or she had a traumatic brain injury as a baby. A regular MRI usually cannot be used to detect post-concussion syndrome. A regular MRI detects structural damage to the brain, but PCS is not caused by structural damage. Because of this, many people with PCS are told that they are fine and that all symptoms are in their heads because of normal MRI results.

As we now know, that is simply false. After the acute period after traumatic brain injury, neuroradiology is used to detect lesions, especially indications of microscopic injury to the axons (nerve fibers), which may explain the persistence or worsening of TBI-related symptoms. Magnetic resonance imaging (MRI) is a powerful diagnostic tool that can detect signs of injury such as tiny bleeding (microhemorrhage), small areas of bruising (contusion), or scarring (gliosis), which are invisible to computed tomography. Newer and more specialized types of MRI can evaluate brain structure at an even finer level or measure brain function to detect alterations in brain structure and function due to traumatic brain injury.

However, since the microscopic injury to the brain can be a cause of problems, even MRI may not be able to detect any abnormalities in a patient with TBI. Long after the injury, MRI and CT can show brain atrophy, which occurs when dead or injured brain tissue is resorbed after TBI. Because injured brain tissue may not fully recover after a traumatic brain injury, changes due to TBI can be detected for many years. The postconcussion syndrome affects the ability of neurons (brain cells) to indicate the right amount of blood to carry out certain processes (among other things), but does not cause structural degradation to the cells themselves.

You may still have a valid personal injury claim, even if your diagnostic tests for a brain injury were normalized. Your doctor may order a brain scan to make sure you don't have a skull fracture or serious brain injury. This database is extremely valuable for identifying where and how the brains of patients with PCS deviate from the norm. Although contrast angiography has been the gold standard for the diagnosis of vascular lesions, MRI, MRA, and CT angiography (CTA) are increasing in use and capacity.

Although one study showed that patients with abnormal coagulation studies were more likely to have a late brain injury on CT, 34, it has not been clearly established whether anticoagulation or coagulopathies should affect the decision to obtain images. A magnetic resonance imaging (MRI) machine uses strong magnetic fields and radio waves to create detailed pictures of organs and tissues inside the body. Although short-term symptoms don't always show up right away or can go away fairly quickly, that doesn't mean that later the effects of a concussion or traumatic brain injury (TBI) aren't long-term. Many traumatic brain injuries often lead to psychological problems, and since symptoms are not always present right after the initial injury, the cause of the psychological behavior change may not be properly diagnosed.

Many brain injury victims need surgery, physical therapy, occupational therapy, and other intensive treatment. A CT scan is usually the best first test to use if your doctor thinks you have a skull fracture or bleeding in your brain. We have covered the types, symptoms, and treatments for traumatic brain injuries after a work accident or work accident in a previous blog post.
