What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 Results may not be published yet.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 This study
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This status has not been confirmed recently, so it may be out of date.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 aimed to see if contrast-enhanced ultrasound and elastography can measure brain blood flow and stiffness in preterm babies as well as MRI does. Researchers planned to scan preterm infants when they reached their due date and compare the results with standard MRI. However, the study was withdrawn before any babies were enrolled, so no results are available.

What this could mean

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

Active substance
Sulfur hexafluoride (SonoVue)
What this could lead to
If successful, this could provide a safer, bedside alternative to MRI for evaluating brain health in preterm infants.
What could go wrong
The study was withdrawn before enrolling any participants, so no data were collected. The approach is still experimental and may not prove reliable compared to MRI.
