Comparing self-reporting concussion assessments with an objective Diffusion Tensor Imaging (DTI) and resting state MRI (rsMRI) based measure

Traditional concussion self-reporting has significant limitations due to its subjectivity and inconsistency, therefore a more objective MRI-based approach is proposed in this research. A concussion population was assessed using the traditional PCSS method versus DTI anisotropy analysis and rsMRI complexity analysis. Concussed patients were compared to large age and sex matched datasets and a Z-transform was used on white and gray matter ROIs to identify injured areas in the cerebrum. A weighted mean equation was then used to compare Z-scores to the 7-point PCSS. Results confirmed sex differences in self reporting and shows promise as a future objective assessment tool.
