This test reveals blood flow to regions of the brain to determine if enough blood is reaching all areas. Patients breathe xenon (an odorless, colorless gas), which acts as a contrast agent to show regions of low and high blood flow.
Note the areas of red and yellow, which indicate a higher volume of blood flow to the brain when challenged with Diamox.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
