SWI is an MRI sequence (like T2* is an MRI sequence, for e.g.) especially useful to detect blood.

DTI also does not need any changes to the MRI device itself, it just a software package, too, so actually it should be available. However, the ordinary radiologist does not perform DTIs yet.
If you end up getting one, maybe it would be worth sharing your experience here to others. Also it might be worth to start a thread on this topic.

However, the problem is that the imaging will not really give the patient a profit, as there is not a medical therapy, yet, which I do not need to tell anybody here.


Starr,
Sorry for sort of hijacking your thread. I suggest, if anybody has to share something about DTI, it will be better to do it a new thread.
