Brain Imaging After Mild Traumatic Brain Injury Can Show Lesions

Brain Imaging

When medical professionals examine the brain tissue of people with a traumatic brain injury (TBI) after death, they can observe lesions on the brain tissue. The lesion sizes vary in direct relation to the severity of the injury. A recent study suggests that, contrary to previous knowledge, these lesions are visible immediately after a mild TBI (MTBI). Being able to distinguish the lesions post-injury can affect the type of treatment administered.

In the study, patients at two hospitals received MRIs immediately after being admitted to the hospital with a TBI. Some of the patients had experienced brain hemorrhaging and others had microbleeding and linear lesions. If doctors can determine the nature of a TBI early on, they can prescribe the most effective treatment in each case. This research will inform future TBI treatment strategies.
