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 Results may not be published yet.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.

Summary

This study is testing a new MRI receiver coil designed specifically for pregnant women to see if it can produce clearer and faster images of the fetus. Researchers will compare the quality of these research MRI scans to standard clinical fetal MRI and ultrasound. The study will enroll 300 pregnant women, including those with healthy pregnancies and those with concerns about fetal or placental abnormalities.

What this could mean

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

Active substance
Investigational MRI coil designed for pregnant women
What this could lead to
If successful, this could lead to clearer and faster fetal MRI scans, helping doctors better assess fetal health during pregnancy.
What could go wrong
This is an early-phase device study focused on image quality, not treatment. The new coil may not significantly improve images or may be less comfortable for some women.

Expected to finish

Jun 2028

An estimate. End dates often move.
