New imaging test could spot rare childhood disease sooner
NCT ID NCT04943211
First seen Jun 24, 2026 · Last updated Aug 21, 2026 · Updated 2 times
Summary
This study aims to improve how doctors diagnose and monitor histiocytosis, a rare disease that causes abnormal cell growth, in children under 18. Researchers will use a special imaging agent called fluorodeoxyglucose (18F-FDG) in PET-CT scans, along with genetic testing of tumor tissue and blood. The goal is to see how well these methods track the disease over time, potentially leading to earlier detection and better outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- fluorodeoxyglucose (18F-FDG)
- What this could lead to
- If successful, this could lead to better, earlier detection of histiocytosis in children and more precise monitoring of the disease.
- What could go wrong
- This is a single-center, early-phase trial focused on imaging, not treatment. The results may not apply broadly, and the imaging agent carries standard radiation risks.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patient under 18 years of age at the time of inclusion. 2. Histopathologically confirmed or suspected histiocytosis (based on prior test results). 3. Signing of informed consent for trial participation according with current legal regulations. Exclusion Criteria: 1. Lack of inclusion criteria. 2. Pregnancy. 3. Other acute or persistent disorders, behaviors or abnormal laboratory test results, which might increase the risk related to the participation in this clinical trial or to taking the study drug, or which might influence the interpretation of the study results, or which, in the investigator's opinion, disqualify a patient from participating in the trial.
