Hello list,
I have some questions about preparation of SPECT images (probably the same as PET) for spm analysis...
What should be orientation of slices used.... should we enter trans-axial slices or oblique slices to spm? What is the slice thickness that we should use?
Should the activity in the brain images be somehow normalised before images can be compared? Because when we inject the same activity it distributed differently in different patients and probably this should be accounted for in analysis...
I would appreciate your opinion on this.
Petra
