A new form of magnetic resonance imaging (MRI) called Diffusion Tensor Imaging (DTI) is able to detect microstructural changes in brain tissue, which enables physicians to better predict the outcome after a patient suffers mild traumatic brain injury.
This is according to a new study published in the Journal of Neurotrauma and could have a significant impact on treatment and aftercare for patients. Those who suffer an acute head injury, such as mild traumatic brain injury (mTBI), are likely to suffer ongoing dysfunction up to six months after their injury.
An international research team conducted the study, which was the first of its kind to compare DTI to conventional imaging, as well as looking at clinical factors for outcome prediction in individual patients with mTBI.
DTI showed significant differences between the white matter of mTBI patients who had positive versus negative findings on CT and MRI evaluation.
John Povlishock, editor-in-chief of Journal of Neurotrauma and professor at the Medical College of Virginia Campus of Virginia Commonwealth University, said the study "addresses an issue of continuing controversy and confusion".
