What is the role of advanced neuroimaging biomarkers in TBI prognosis?

• A. They are routinely used to replace clinical assessment.
• B. Advances are fully established in standard care.
• C. MRI biomarkers are proven to replace clinical assessment.
• D. MRI-based biomarkers help predict outcomes and tailor rehab; still mainly research-based.

Answer: (D)

Advanced MRI biomarkers give a window into brain injury that goes beyond what routine scans show, by capturing microstructural damage, network connectivity, and metabolic changes. These measures can help forecast later function and inform rehabilitation planning—such as targeting therapies to specific deficits or adjusting intensity based on predicted recovery. However, they aren’t yet used as a replacement for clinical assessment or standard imaging, and there isn’t universal consensus on how to apply them in everyday care. The field is still largely in the research realm, with ongoing work to standardize techniques and confirm their predictive value across different patients. So, while MRI-based biomarkers have real potential to improve prognosis and customize rehab, their routine clinical use remains on the horizon.
