Return to Play Following Concussion: Role for Imaging?

Area of Science:

• Neuroscience
• Sports Medicine
• Radiology

Background:

• Traditional concussion diagnosis relies on subjective clinical assessments.
• Limitations in subjective assessments necessitate objective diagnostic tools.
• The need for enhanced concussion management and accurate return to play (RTP) protocols is critical.

Approach:

• Review of advanced neuroimaging modalities for concussion assessment.
• Exploration of techniques including Magnetic Resonance Spectroscopy (MRS), Diffusion Tensor Imaging (DTI), Functional Magnetic Resonance Imaging (fMRI), and Positron Emission Tomography (PET).
• Inclusion of Vestibulo-ocular dysfunction screening and eye tracking for functional assessment.

Key Points:

• MRS detects metabolic changes, DTI reveals white matter microstructural alterations, and fMRI assesses neuronal activity.
• PET offers insights into metabolic disturbances and long-term concussion effects.
• Vestibulo-ocular screening and eye tracking evaluate specific functional deficits.

Conclusions:

• Neuroimaging holds significant potential for enhancing concussion diagnosis accuracy.
• These techniques can provide objective data to guide return to play (RTP) decisions.
• Continued research and standardization are essential for clinical integration of neuroimaging in concussion management.
