Summary

This study is testing whether a combined PET and MRI scan, using a radioactive tracer called FDG, can accurately locate the source of chronic pain that persists after joint surgery. Researchers will scan 128 people with and without pain to see if the scan can spot where pain is coming from. If it works, it could help doctors treat chronic pain more effectively by targeting the right area.

What this could mean

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

Active substance
FDG radiotracer (a radioactive sugar used for imaging)
What this could lead to
If successful, this could give doctors a reliable way to pinpoint the exact cause of chronic pain after surgery, leading to more targeted and effective treatments.
What could go wrong
This is an early-stage imaging study, not a treatment trial. It may not find a clear pain source in all patients, and the results may not change how pain is managed in practice.
