Dear SPM-help group,
We have a paired study design of the same subjects (scan 1-scan 2) and we
would like to see if there is a correlation between initial tracer binding
obtained in scan 1 and reduction (%reduction preferred over absolute reduction)
in binding observed between scan 1 and scan 2.
Is there a design to be used to investigate a positive or negative
regional correlation between (Scan 1-Scan2) and Scan1 on a voxel by
voxel basis ?.
Hope I get a reply soon,
Nese
