Is this trial a fit for you?

Likely a good fit

Ideal candidates include children and young adults with proven solid tumors or newly diagnosed masses suspected to be solid tumors.

Probably not a fit

Patients with contraindications for MRI or PET/MR, such as those with cardiac pacemakers or CNS primary tumors, may not benefit from this study.

What this trial studies

This observational study aims to evaluate and compare the effectiveness of whole body magnetic resonance (MR) imaging, whole body positron emission tomography (PET)/MR imaging, and PET/Computed Tomography (CT) imaging in diagnosing tumors in pediatric and young adult patients. The study will assess the sensitivities, specificities, and diagnostic accuracies of these imaging modalities to identify significant differences in their performance. Participants will include those with confirmed solid tumors or suspected solid tumors, and the study will collect data for analysis in an image registry.

Why it matters

Potential benefit: If successful, this study could enhance diagnostic accuracy for tumors in children and young adults, leading to better treatment outcomes.

How similar studies have gone: Other studies have shown success in comparing imaging modalities for tumor diagnosis, but this specific approach may provide novel insights.

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.
