Standard protocols and parameters:
All sites have agreed upon the following minimum standards for structural, resting-state and diffusion tensor imaging.
The sites have consented to limit data acquisition to 3 Tesla MR scanners, using a head coil with 12, preferably 20, 32 or 64 channels.
A measurement of the magnetic field homogeneity (field map) is conducted once per participant.
After final agreement on the measurement parameters, the particular configuration for all operating MR scanners is to be deduced, coordinated between sites and documented.
