SPECT scans

I suffered a serious head injury, but doctors are still at a loss why I just fell unconscious without warning.  MRI is normal, EEG shows abnormalities in the left front of the brain.  The spect however shows serious perfusion restriction in the front left temporal lobe and in a few other areas also some restriction.  My question is if there is a standard for SPECT scans and to what extent can this be used as a diagnostic tool.  Several doctors have widely varying opinions of the validity of these type of scans.  I suffer from multiple symptoms and disorders to such an effect that I am unable to do work.
