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 Results may not be published yet.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 This study
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

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

Summary

This study investigates whether MRI can be used instead of CT to diagnose the cause of acute abdominal or pelvic pain in women aged 18-40 after an ultrasound has not provided a clear answer. Participants receive both an MRI and a CT scan, and researchers compare how well each test identifies the problem. If MRI proves accurate enough, it could become the preferred follow-up test, sparing young women from radiation exposure.

What this could mean

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

Active substance
Additional MRI Examination
What this could lead to
If MRI proves as accurate as CT, young women with abdominal pain could avoid radiation from CT scans while still getting a clear diagnosis.
What could go wrong
MRI may not be as reliable as CT in all cases, and some women might still need a CT if MRI is unclear. The study is relatively small and observational.
