Question Posted 05/29/15:
If I had regular MRI last year that was normal , can DTI software be used to reevaluate that older MRI scan , as I have history of head trauma and symptoms that suggest (TBI) (MTBI) , but have had normal CT and MRI thus far . Or does a totally new MRI (DTI) have to be performed
Response posted 06/04/15 by ADNI MRI Core:
Thank you for your question to the ADNI MRI Core.

Unfortunately, yes an exam with specific DTI sequences is needed unless DTI was included in the prior exam.

Thank you ADNI MRI Core.
