Figure 1 shows scatter plots of the T 1 & T 2 values obtained in the twelve tubes of the calibrated phantom. Applying the iterative reconstruction on the subset of only four PCs enables a significant improvement over a naïve fit of this subset. The accuracy (T 1 |T 2 ) was 9.5|11% for the full set, 120|110% for the subset with naïve fit and 12|15% for the subset with iterative reconstruction. The precision was 5.5|7.0% for the full set, 56|53% for the subset with naïve fit and 6.9|9.3% for the subset with iterative reconstruction.
