Dear SPM users
I am working on a PET receptor study where I have 8 subjects with 2 scans
(baseline/activation) each. I have calculated binding potentials (BP) in
PMOD, and now I want to compare my two conditions in SPM. I am using paired
t-test, but alternating with the different options give me quite different
results. I was wondering if anyone in here have some experience in analysing
similar data? Should I use global normalisation, and if so overall grand
mean scaling or normalisation with proportional or AnCova?
Thank you for your help!
Best regards,
Trine Hjørnevik
