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 Results may not be published yet.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

Summary

This study tested a special breathing technique during PET scans to get clearer images of lung tumors. 103 people with small lung nodules (under 35 mm) had both a standard PET scan and an extra scan where they held their breath. The goal was to see if this reduces blurring from breathing and helps doctors spot cancers more accurately. The study is complete and focused on improving diagnosis, not treatment.

What this could mean

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

Active substance
18F-FDG (a radioactive tracer used in PET scans)
What this could lead to
If successful, this method could help doctors see small lung tumors more clearly, leading to more accurate diagnoses.
What could go wrong
This is a small, completed study focused on imaging technique, not a treatment. The method may not work for all patients or tumor types.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
