Hi! I'm curious to see how the B1 map will help as well. Its been a while since our team has thought about this, but I'll show this to our MR physicist and let you know. We are continuing to pursue obtaining a GE MPRAGE to see if that would help, but its been slow going. When we do and are able to run some tests, we'll post the results
