Question Posted 07/04/17:
May I know the difference between MP-RAGE , MP-RAGE SENSE2, MT1__N3m and field mapping sequence? and what is the best for analysis? Thank you in advance

Thank you for your question to the ADNI MRI Core.

MPRAGE is a 3DT1 scan, MPRAGE SENSE is a accelerated 3D T1 Scan and MT1_N3M is a normalized corrected scan using n3m correction of the one of 3DT1 scans. Field Mapping is used for distortion correction.

Where possible it is suggested to use the n3m scans for analysis.
