When are our stroke doctors going to do something similar? With no objective diagnosis of the damage from a stroke there is absolutely no way to correlate successful stroke rehabilitation protocols to the damage location. And then maybe we can get away from the appallingly stupid saying of 'All strokes are different, all stroke recoveries are different'.

Diffusion Tensor Imaging (DTI), a specialized magnetic resonance imaging
(MRI) technique that detects microstructural changes in brain tissue,
can help physicians better predict the likelihood for poor clinical
outcomes following mild traumatic brain injury compared to conventional
imaging techniques such as computed tomography (CT), according to a new
study published in Journal of Neurotrauma, a peer-reviewed journal from
Mary Ann Liebert, Inc., publishers. The article is available free on the
Journal of Neurotrauma website until October 17, 2014.
The
ability to predict which patients who experience an acute head injury
such as mild traumatic brain injury (mTBI) are likely to suffer ongoing
dysfunction 3 or 6 months post-injury is important for providing optimal
care. Esther Yuh and coauthors from University of California, San
Francisco, Erasmus MC-University Medical Center (Rotterdam, The
Netherlands), Mount Sinai School of Medicine (New York, NY), Seton Brain
and Spine Institute (Austin, TX), University of Pittsburgh Medical
Center (PA), University of Texas (Austin), Antwerp University Hospital
(Edegem, Belgium), and University of Cambridge Addenbrooke's Hospital
(Cambridge, UK), present the results of the first published study that
compares DTI to conventional imaging and 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, as described in the
article "Diffusion Tensor Imaging for Outcome Prediction in Mild
Traumatic Brain Injury: A TRACK-TBI Study."
John T. Povlishock,
PhD, Editor-in-Chief of Journal of Neurotrauma and Professor, Medical
College of Virginia Campus of Virginia Commonwealth University,
Richmond, notes that "this exceptionally well done study addresses an
issue of continuing controversy and confusion. The authors make an
extremely important observation that MRI studies, including DTI
parameters, are integral in informing prognosis after mild TBI. When
taken together with the other publications from the TRACK-TBI Study
Group, these findings should prove invaluable in assessing the
occurrence of mild TBI and informing patient outcome."
