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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares three ways to image the lungs of infants: CT scans, electrical impedance tomography (EIT), and lung ultrasound. The goal is to see how well the non-invasive methods (EIT and ultrasound) match up with CT in detecting collapsed or overinflated lung areas. Ten infants who already need a chest CT will also receive EIT and ultrasound, allowing researchers to compare the results. The findings may help develop safer bedside imaging options for babies.

What this could mean

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

What this could lead to
If successful, this could help doctors use safer, radiation-free imaging methods like EIT and ultrasound at the bedside for infants.
What could go wrong
This is a very small observational study with only 10 infants, so findings may not apply broadly. It is designed to generate hypotheses, not prove a new standard of care.
