What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 compares whole-body MRI, PET/MR, and PET/CT scans to see which is best at finding tumors in children and young adults with solid tumors, lymphoma, or osteosarcoma. Researchers will check how many tumors each scan detects and measure their metabolic activity. The goal is to improve diagnosis while possibly reducing radiation exposure from scans.

What this could mean

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

What this could lead to
If successful, this could help doctors choose the best imaging method for diagnosing tumors in children, potentially reducing radiation exposure.
What could go wrong
This is an observational registry, not a treatment trial. It may not lead to immediate changes in care, and results might not apply to all tumor types.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with proven solid tumors or newly diagnosed mass strongly suspected to represent a solid tumor. * We might also include some patients with leukemia if there is concern for a focal lesion in any of their organs. * Participant's parents (if participant is under 18) or the participant (if participant is 18 years or older) must willingly give written informed consent prior to any image transfer to the image registry. Exclusion Criteria: * Patient has contraindications for MRI or PET/MR. This includes patients with cardiac pacemakers or intracranial vascular clips as well as patients with a blood glucose level \> 200 mg/dl. * Lack of parental permission (if participant is younger than 18) or lack of informed consent (if participant is at least 18 years of age). * Patient has a CNS primary tumor. * Pregnant women and fetuses
