Detailed results of the adjusted ROC analysis for ADC and all 3 raters at 1.5 and 3 T.

am0: adjusted model, adjusted for lesion volume, sex, thrombolysis, NIHSS).
bm1: m0 additionally adjusted for age.
cm2: m1 additionally adjusted for time (stroke-to-imaging).
dm3: m1 and rater specific ADC-ROI values.
In contrast to DWI (see table 3), adding the ADC-ROI-values for each rater (model 3[m3]) as a variable led to only a bad to moderate accuracy for the prediction of FLAIR-hyperintensities for each rater in comparison with the basic models (m0 and m1). The AUC was even inferior to m2, which was based on “time-from-stroke-onset”. Thus, ADC maps cannot reliably predict FLAIR-hyperintensities in contrast to DWI-maps. Please see figure 3 for the respective ROC-curves for each model. AUC, Area under the curve.
