Question Posted 03/31/14:
How can I determine which subjects have MRI (MPRAGE, resting state fMRI, PET and DTI) at various time points? Been trying to use the advanced search but have not been successful.

Thank you for your question to the MRI Core.

In ADNI2 MRI subjects will always have a T1 scan, but will not have both fMRI and DTI as those sequences are acquired on different system types. I.E. fMRI is performed on Philips systems and DTI on GE systems.

As far as PET scanning, can you please direct to the PET core.
