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.

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.
