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.

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 Results may not be published yet.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

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.

Summary

This study collected PET brain scans from 41 healthy adults aged 20-65 to create a reference database. Doctors can compare these normal scans to those of epilepsy patients to better locate the brain area causing seizures. The goal is to improve surgical planning for patients whose seizures are not controlled by medication.

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 database could help doctors more accurately pinpoint where seizures start in the brain, improving surgical planning for epilepsy patients.
What could go wrong
This is a small, observational study in healthy people only. The database may not work as well in real-world patients or different age groups.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

41 people

The number who actually took part.

Started

Sep 2014

Finished

Jul 2017

Lead sponsor

Other sponsor

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

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

20 to 65 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
