The neuropsychologist I am working with tells me that he doesn't like
to work with SPECT, doesn't find it very useful, etc.  I am somewhat
uneasy about his apparently casual dismissal of SPECT and would like
to hear from the people in this newsgroup.  Is this your experience,
too?  

In your experience what kind of useful information can one reasonably
expect from a brain SPECT?  How closely do SPECT findings correlate
with the results of neuropsychological testing?
