ReviewBlunt Craniocervical Trauma: Does the Patient Have a Cerebral Vascular Injury?
Blunt cerebrovascular injury involves injury to the carotid and/or vertebral arteries sustained via generalized multitrauma or directed blunt craniocervical trauma. Stroke remains the most consequential outcome. ⋯ Discussion centers on the increasing reliance on multidetector computed tomography angiography for screening, considering relevant clinical criteria for determining screening. Imaging protocols, imaging findings, injury grading, pearls, and pitfalls are discussed.

ReviewAcute Neurologic Syndromes Beyond Stroke: The Role of Emergent MR Imaging.
MR imaging with diffusion-weighted imaging has been essential in the evaluation of acute stroke but is also crucial for the diagnosis, treatment, and follow-up in patients with various nonischemic disorders, including infectious processes, trauma, toxic/metabolic disorders, and other abnormalities. This article reviews various disorders with diffusion abnormality that can be commonly seen in the emergency setting.
