3T ADNI GE G3 M4 Software, TwinSpeed Gradient and 8-channel Brain Coil
Set up the patient according to the ADNI instruction manual. Use the 8-channel brain coil.
Use the electronic ADNI protocol that has been loaded on your scanner.
NOTE: The "adni" pulse sequence used for series 2 and 3 is a works in progress pulse sequence
that ADNI sites obtain from GE Healthcare.
To avoid prolonging the scan time for Series 6, you will need to accept
the "First Operating Mode" pop-up in series 1.
Consult the scanner's user's manual to understand this choice, and its implications.
