Sirs and Ma’ams-
Many of you had the good fortune of seeing Dr. Orrison’s neuro-radiology presentation on December 5th at the “HBOT in TBI” Consensus Conference. Others have seen Dr. Harch’s SPECT brain images of patients he has treated over the past 18 years. The quote below will be of interest. At Dr. Orrison’s presentation, he showed 3 patients’ whole brain CT scans, from his practice, who had been treated with HBOT 1.5 by three different physicians. All patients had major recovery of brain function.
Here is his quote regarding Dr. Harch’s SPECT brain images:
“Dr. Harch’s use of SPECT brain imaging to examine the changes in the brain before and after hyperbaric oxygen therapy is scientifically accurate and valid. Multi-detector SPECT imaging is one of the only neuroimaging methods with sufficient utility to allow this type of longitudinal evaluation.
The improvement in brain perfusion demonstrated by Dr. Harch pre and post HBOT is impressive and objective evidence of improved cerebral blood flow in these patients. This is the same type of change that we have recently demonstrated using the new method of whole brain CT. In addition, the clinical observations and neuro-psych testing done by numerous physicians at different locations further verifies Dr. Harch’s results and correlates with the objective findings observed on the SPECT images.”
