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.

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 a portable MRI machine to look for brain injury in patients who have had a cardiac arrest. Researchers will scan the brain multiple times over several days to see how injuries change. The goal is to make brain imaging available at hospitals without specialized scanners and to find signs that help decide which patients might benefit from future treatments. About 60 adults who remain unresponsive after cardiac arrest will take part.
