Test of Reproducibility of [15O]H20-PET Assessment of Brain Perfusion
This study tests how repeatable a brain scan is. Researchers use a PET scan with a radioactive water tracer to measure blood flow in the brain, scanning the same people more than once. The aim is to see whether results hold steady, which matters for later research on small blood vessel disease. No phase is listed. It is a diagnostic test, not a treatment.
