Advanced MRI Enhances Prognosis for Concussion Patients

Diffusion tensor imaging (DTI) identifies long-term risks missed by standard CT scans, aiding in better treatment plans.

Overview

  • DTI detects subtle brain changes linked to persistent concussion symptoms.
  • Standard CT scans often fail to identify abnormalities in concussion cases.
  • Blood biomarkers can indicate which patients may benefit from DTI scans.
  • DTI significantly improves the accuracy of concussion prognosis models.
  • Researchers aim to integrate DTI and biomarkers into routine clinical practice.
