Detecting early skull–brain injury from repeated minor sports head impacts using MRI elastography

MRE elastography-based detection of impaired skull-brain decoupling after repetitive subconcussive sports impact

NIH-funded research Mayo Clinic Rochester · NIH-11369149

A special MRI-based scan looks for early changes where the skull meets the brain in people—especially contact-sport athletes and youth—who have had repeated small head impacts.

What this research studies

You would get a noninvasive MRI exam called harmonic MR elastography (MRE) that measures how the tissues at the skull–brain interface move in response to tiny vibrations. Researchers will compare people with different histories of repetitive subconcussive head impacts, including some followed over time, to see how MRE measurements change with exposure and recovery. The team focuses on the pia–arachnoid complex and other interfaces that may become mechanically altered long before symptoms appear. Scans are done at Mayo Clinic using specialized imaging sequences developed in the prior grant cycle.

Who could benefit from this research

Good fit: Ideal candidates are people—particularly youth and athletes in contact sports—with a history of repeated subconcussive head impacts who can travel to Mayo Clinic for imaging and follow-up.

Not a fit: People without a history of head impacts, or those who cannot undergo MRI (for example, because of a pacemaker or other contraindication), are unlikely to benefit or participate.

Why it matters

Potential benefit: If successful, this could identify early, otherwise invisible damage from repeated minor head impacts and help guide monitoring, rest, or protective strategies to reduce long-term brain injury risk.

How similar studies have performed: Prior pilot work from this team produced the first evidence that MRE can detect skull–brain mechanical changes after repetitive subconcussive impacts, but larger clinical validation remains novel and ongoing.
