Hi all,
We want to analyze a PET study comparing two different groups (3
patients=group1,and 3 healthy subjects=group2). For each group, three
different conditions (A:rest, B:activity 1, C: activity 2) have been
examined. There are 4 scans for each condition/subject. Now we want to
calculate differences concerning overall activity (taking together
condition B and C) against rest (condition A) between the two groups, i.e.
analyse differences in activation/deactivation between patients and
normals.{ ((B+C)-A)group1 against ((B+C)-A)group2}
Can anyone tell us which is the appropriate study design setup in SPM 96b
to do this and how the contrasts should be chosen.
Any help would be highly appreciated
