Reference and predicted results were compared, for each one of the
predicted signal types (T1,
T2, MPRAGE, FLAIR,
T1-, T2-, and
PD-weighted). Each plot, similar to a Bland-Altman analysis, combines results
from all volunteers. Plots in (c-g) were normalized by defining
‘1.0’ as the signal level of white matter. Gray dashed lines
represent the 95% limits of agreement, and solid red lines show the bias.
Quantitative T1 (h) and
T2 (i) values were further compared, for
reference and predicted results, based on white matter (white boxes) and
thalamus (gray boxes) ROIs. The plots in (h,i) combine data from all 8 subjects.
Outliers are shown with gray ‘×’ markers.
