SER kinetics compared to final surgical pathology

Variable	No invasion at pathology Median (IQR)	Invasion at pathology Median (IQR)	p-value
At PE = 70%
% Washout	9 (21)	14 (11)	0.261
% Plateau	26 (15)	29 (9)	0.252
% Persistent	60 (36)	54 (9)	0.697
At PE=130%
% Washout	9 (37)	36 (23)	0.006^*
% Plateau	34 (51)	44 (23)	0.486
% Persistent	18 (35)	21 (25)	0.383

PE: percent enhancement defining the minimum enhancement threshold

IQR: interquartile range, the range between the 25^th and 75^th percentile

p value reaching significance. All p values were obtained by Wilcoxon rank-sum test for non-normal data distributions.
