What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether a very powerful 7 Tesla MRI can detect tiny brain injuries in people with post-concussion syndrome after a mild head trauma. Researchers will scan 100 patients one week after their injury and compare the results to standard tests. The goal is to see if this advanced imaging can better diagnose lingering symptoms.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
7 Tesla MRI scan
What this could lead to
If successful, this could provide a more reliable way to diagnose post-concussion syndrome after mild head injury.
What could go wrong
This is an early-stage study with only 100 participants, and the 7T MRI is not widely available. It may not prove better than standard methods.
