Question Posted 10/24/16:
I noticed, in the data collections, that different specifications are written regarding the scans : IR-SPGR, wacceleration calibration scan, 3-plane localizer, MPRAGE, MPRAGE GRAPPA2, MPRAGE SENSE 2, ... If I want the MPRAGE images, should I only download the images where the description MPRAGE is written ? What is the difference between MPRAGE and MPRAGE SENSE 2 or MPRAGE GRAPPA 2? Is there a file describing and comparing these specifications ?

Thank you for your question to the ADNI MRI Core.
The difference between those series is that SENSE (Philips) and GRAPPA (Siemens) are factor of 2 accelerated scans and just MPRAGE is non accelerated.
Yes, If you wished only for non accelerated scans you should download series with only MPRAGE in the series description.
Download questions can be directed to LONI at: dba@loni.usc.edu
