Hi Ezra,
I'd love to hear otherwise if someone has established some robust signal processing approaches to do this automatically, but I'm not aware of any good reliable ways to do this in a automated fashion.  It is time consuming, but you have to put eyes on the data.

cheers,

Subject: [Freesurfer] quick quality assessment for MPRAGE images

Dear Freesurfer Users,

I have a large number of T1 MPRAGE scans collected on a 3T Siemens Trio scanner that I would like to run through recon-all to get cortical thickness values.  However, some of the MPRAGE scans are contaminated by subject motion, but the extent of this varies from scan to scan.   Is there a quick automated way to assess whether each MPRAGE is high-quality enough to bother with running through recon-all?  

Thanks!
Ezra
