Table 1.

Number of exams available (for a total of 162 women) at each treatment time point (with the number of cases with a recurrence vs.no recurrence in parentheses)

	Exams with at least 3 acquisitions*	Functional Tumor Volume	Both
Pre-treatment baseline	141 (40 vs. 101)	137 (39 vs. 98)	137 (39 vs. 98)
Early treatment	142 (37 vs. 105)	143 (38 vs. 105)	141 (37 vs. 104)
Both at baseline and early treatment	127 (37 vs. 90)	124 (26 vs. 88)	123 (36 vs. 87)

*For automated tumor segmentation, a dynamic contrast-enhanced MR exam needed at a minimum to consist of a pre-contrast and two post-contrast images; At baseline, all available exams met this criterion while at early treatment a single exam was eliminated from our automated analysis
