Text

The SNR for each registration method at each MRI was about the same: MRI 1=10.58 and MRI 2=10.55 for the independent method; MRI 1=10.58 and MRI 2 =10.57 for the forward sequential method; and MRI 1=10.49 and MRI 2=10.55 for the backward sequential method. None differed significantly between scans within a method. Further, none of the SNR estimates correlated significantly with age, and none differed by sex.
