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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether a low-dose CT scan, enhanced with deep learning image reconstruction, can diagnose acute abdominal conditions as accurately as a standard CT scan. 246 adults with abdominal pain received both scans, and the low-dose version used less than 30% of the usual radiation. The goal is to see if AI can maintain diagnostic quality while reducing 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
low-dose CT with deep learning image reconstruction
What this could lead to
If successful, this could allow doctors to use lower-radiation CT scans for diagnosing acute abdominal pain without losing accuracy.
What could go wrong
This is a completed observational study, not a treatment trial. The low-dose CT may still miss some conditions compared to standard CT, and results may not apply to all patients.
