What is a SPECT scan?
A SPECT scan shows brain function by mapping blood flow in the brain, or cerebral perfusion. The scans show areas of hypoperfusion, where brain activity is too low, and hyperperfusion, where brain activity is too high. Before and after SPECT scans show the changes in brain activity resulting from HBOT. Please contact your doctor to see if before and after SPECT scans are advisable.
