PET scans could revolutionize monitoring of rare inflammatory disease
NCT ID NCT07712172
First seen Jul 17, 2026 · Last updated Jul 17, 2026
Summary
This study explores whether a special type of PET/CT scan, using a radioactive tracer called 18F-FDG, can accurately measure disease activity in people with granulomatosis with polyangiitis (GPA), a rare condition that causes inflammation of blood vessels. Researchers will compare the scan results with a standard clinical scoring system to see if the imaging technique can provide a more objective way to track the disease. The study involves 31 adults with newly diagnosed or relapsed active GPA.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-FDG (a radioactive tracer used in PET/CT scans)
- What this could lead to
- If successful, this could lead to a more accurate, non-invasive way to monitor GPA disease activity, potentially improving treatment decisions.
- What could go wrong
- This is a small, early observational study, so results may not apply broadly. The scan's sensitivity and correlation with standard scores may be limited.
