Table 1. Mean and corresponding sample standard deviations for FGT volume, total breast volume and %FGT measured from the different Dixon datasets in 10 volunteers.

Also shown are the mean and corresponding sample standard deviations of the calculated signal intensity correction factors applied to each sequence.
