Subacute MR Imaging: Diffuse Axonal Injury, Brain Stem Lesions and Prognostic Factors
CT is insufficient in the diagnosis of diffuse axonal injury (DAI) and brain stem injury (BSI). Such injuries are very common and clinically important in severe traumatic brain injury, especially in the context of high-energy trauma. Magnetic resonance imaging (MRI) is the superior image modality to gain an overview of the traumatic lesions in the brain parenchyma. The neuroanatomic and prognostic information provided by MRI is important during the subacute phase of clinical management and rehabilitation. Thus, MRI should be considered in all patients with severe TBI.
