I'm trying to compare the changes in DTI in a case.
I have several studies from one subject, all of them have DTI, but I can't observe changes, probably because of the differences in the studies.
Some studies were made in Philips Achieva 1,5T and other in a GE HD 1,5T.
The good thing is that all studies have 33 directions.
But it's the only similarity.
Can I normalize these studies?
