New PET scan method could rival standard test for brain blood flow
NCT ID NCT06584747
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a PET scan can measure brain blood vessel response to a drug called acetazolamide as well as the standard scintigraphy method. Nineteen adults with narrowed brain arteries will undergo both scans. The goal is to see if the newer PET approach is a reliable alternative for diagnosing blood flow problems.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Acetazolamide (Diamox)
What this could lead to
If successful, PET scans could replace the older method for assessing brain blood flow, offering a more accessible or detailed diagnostic option.
What could go wrong
This is a small, early-phase diagnostic study with only 19 participants. The PET method may not prove as accurate as the standard test, and results may not apply to all patients.
