ERRATUM
=======


The authors regret that in the article “White Matter Changes Related to Subconcussive Impact Frequency during a Single Season of High School Football” (*AJNR Am J Neuroradiol* 2018;39:[245–51](http://www.ajnr.org/lookup/volpage/39/245); [https://doi.org/10.3174/ajnr.A5489](https://doi.org/10.3174/ajnr.A5489)), the art and legend for Fig 3 did not match. A corrected figure with the original legend is reproduced below.

Fig 3. 
Scatterplot of changes in FXST FA for all subjects across the season. Individual player data are connected by *solid* or *dotted lines* based on the median split of the total number of impacts during the season, as depicted in the legend. The concussed subject is plotted with *triangles*.
