External Email - Use Caution
Hello,
We are working with a large number of acquired imaging and unfortunately, the pulse sequences that have been used are not the same. We have two different groups of pulse sequence: T1-3D-FFE and T1-MPRAGE. Could we use all of these images in the same study?
Thank you in advance for your answer,

I think so, but you would need to include it as a regressor in your group analysis, and you'd need to make sure that your contrast of interest is balanced across sequence (eg, you don't want all your patients for one seq and all your controls on the other)
