Chronic Post-Traumatic Brain Injury, MRI
This axial (cross sectional) gradient echo T2 weighted image demonstrates multiple small areas of hemorrhage, which look black on this type of image Because the temporal lobes are so close to the adjacent bony skull base the brain hits the bone during the injury . This direct physical blow to the brain results in area of hemorrhage (bleeding). Some of the areas of bleeding however are also a result of rotational, shearing of the axons of the neurons which is a specific type of injury in trauma referred to as diffuse axonal injury or shear type injury. Gradient echo T2 images are particularly sensitive to these small types of hemorrhage (bleeding) which are often not identified on routine MR brain imaging.
