Sensitivity, Specificity, and Area Under the Curve of Both Readers for the Prediction of ER Status Using Maximum WTu and Mean WTu ADC and for the Prediction of PR Status Using Maximum WTu ADC

Max WTu ADC	Sensitivity	Specificity	AUC
ER (reader 1)	90%	48%	0.730
ER (reader 2)	70%	70%	0.724
PR (reader 1)	58%	71%	0.656
PR (reader 2)	71%	68%	0.671
Mean WTu ADC	Sensitivity	Specificity	AUC
ER (reader 1)	94%	22%	0.666
ER (reader 2)	68%	63%	0.660

ADC, Apparent Diffusion Coefficient; AUC, Area Under the Curve; DpTu, Darkest Part of Tumor; ER, Estrogen Receptor; Max, Maximum; Progesterone Receptor; WTu, Whole Tumor.
