I want to calculate and compare the SNR of different ROIs in a MP2RAGE image acquired at 7T. A MP2RAGE image is the combination of 2 images acquired at different inversion times. I have the MP2RAGE image and the inv1 and inv2 images, for 2 sessions.
I have looked at the comparisons made by Dietrich et al. (2007) (https://doi.org/10.1002/jmri.20969) about the validity of some SNR calculation approaches. I was wondering if I can have some insights about the best approach for the special case of a MP2RAGE image.
Thank you for your help!
