New scan tracks brain inflammation after radiation in kids

NCT ID NCT05128903

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study uses a special PET scan to measure brain inflammation in children with medulloblastoma who receive whole-brain radiation. Twenty-two participants will be scanned four times over two years to see how inflammation changes. The goal is to understand how radiation affects the brain over time, which may help reduce long-term cognitive problems.

What this could mean

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

Active substance
[18F]DPA714 (a radioactive tracer for PET scans)
What this could lead to
If successful, this could help doctors predict and possibly prevent cognitive side effects from brain radiation in children.
What could go wrong
This is a small, early-phase study (22 participants) that only measures inflammation—it does not test a treatment. Results may not apply to all patients.
