The authors investigated the significance of several clinical and imaging risk factors, most specifically the “cervical seatbelt sign,” in the anterior neck in pediatric patients with suspected blunt cerebrovascular injury as seen by CTA. They found that this common indication for neck CTA was not associated with blunt cerebrovascular injury. With the exception of Glasgow Coma Scale score, no single risk factor was statistically significant in predicting vascular injury.

Malfunction of metal-on-metal hip prostheses may produce visual, hearing, and motor deficits. These authors compared brain volumes, metal deposition, and gray matter attenuation in 2 groups of patients 8 years after surgery. Whole blood cobalt and chromium levels were higher in patients with metal-on-metal prostheses and associated with subtle structural changes in the visual pathways and basal ganglia.
