MRI spots white-matter changes in movement disorder patients
By Edward Susman
People who suffer from idiopathic dystonia may have an underlying structural brain structure anomaly that contributes to the physical spasms that are manifest in the disorder, according to researchers from the University of South Carolina in Columbia. Using diffusion tensor MRI, they scanned patients with and without dystonia, and found white-matter abnormalities in the patients with the disorder.

CTA assesses traumatic neurovascular injury
By Eric Barnes
In the setting of neurovascular trauma, CT's excellent image quality isn't enough to predict complications and manage patients optimally, particularly those who present with few or no neurological symptoms. New markers and tests may eventually improve the ability to predict complications. For now, careful attention to clinical and imaging data is key.
