Diffuse Axonal Injury-MRI
Diffuse axonal injury (DAI) is a frequent result of traumatic deceleration injuries and a frequent cause of persistent vegetative state in patients. DAI typically consists of several focal white-matter lesions measuring 1-15 mm in a characteristic distribution. The most common MRI finding is the presence of multifocal areas of abnormal signal (bright on T2-weighted images) at the white matter in the temporal or parietal corticomedullary junction or in the splenium of the corpus callosum.
