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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing NeuroLF, a small brain-only PET scanner, to see if it can produce brain images good enough for diagnosis. Participants who are already scheduled for a routine brain PET scan receive an extra scan on NeuroLF right after their standard scan, using the same radioactive tracer still active in their body. A physician then compares the NeuroLF images with the conventional PET images to judge whether they could be used for diagnosis. The study also checks how easy it is to position patients in the NeuroLF scanner.

What this could mean

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

Active substance
NeuroLF, a small brain-only PET scanner
What this could lead to
If it works, this could offer a smaller, easier-to-use way to take brain PET images, potentially making brain scans more accessible.
What could go wrong
This is an early exploratory study with 26 participants, so it may not show that NeuroLF images are good enough for diagnosis. The device is investigational and has no CE marking.
