      Eleven patients with a history of mild traumatic brain injury and 10 age- and sex-matched controls underwent sodium MR imaging using a 3T scanner. Higher total sodium concentration in the genu and lower total sodium concentration in the splenium was seen in patients with mild traumatic brain injury compared with controls. The ratio of genu total sodium concentration to splenium total sodium concentration was also higher in patients with mild traumatic brain injury. The total sodium concentration appears to be altered beyond the immediate postinjury phase, and further work is needed to understand the relationship to persistent symptoms and outcome.

      Peeking into the Black Box of Coregistration in Clinical fMRI: Which Registration Methods Are Used and How Well Do They Perform?
      F.D. Raslau, L.Y. Lin, A.H. Andersen, D.K. Powell, C.D. Smith and E.J. Escott
      American Journal of Neuroradiology December 2018, 39 (12) 2332-2339; DOI: https://doi.org/10.3174/ajnr.A5846

      This retrospective study of presurgical fMRI for brain tumors compares nonregistered images and 5 registration cost functions: Hellinger, mutual information, normalized mutual information, correlation ratio, and local Pearson correlation. To adjudicate the accuracy of coregistration, the authors edge-enhanced echo-planar maps and rated them for alignment with structural anatomy. The local Pearson correlation is a special-purpose cost function specifically designed for T2*–T1 coregistration and should be more widely incorporated into software tools as a better method for coregistration in clinical fMRI.
