Hello All,
I have estimated V1 using Hinds and Fischl method for some subjects scanned on two different days. I've been going through the V1 surface area data for these. One thing that concerns me is that is seems that very different V1 sizes are reported for the same subject when scanned on different dates and each run through the cross sectional stream. I am trying to check the test-re-test values for these.
Any idea why this is so and whats a better method to do the comparison ?
Thanks
Ri
