Dear SPMers
I have a simple quesntion.
I analyzed PET data using SPM99.
The effect of injected dose was removed by using "Proportional scailing" in SPM.
After the statistical inference, I got the results.
To get rCBF of each subject and scan, I performed VOI analysis.
I chose "effect of interest" but the range of their values was from -1 to 1.
I can not understand what the values means.
Could anyone tell me what the values mean?
