Impact of using an ensemble of CNNs on quantification for the pediatric lymphoma population. Shown are results for SUV_max, MTV, and TLG as summarized by Pearson’s correlation coefficient, R, and the relative percent difference when compared to physician measurements

Method	R	Cases incorrect (of 100)	R	RPD Median [IQR]	R	RPD Median [IQR]
1st CNN initialization	0.73	24	0.89	− 3.5 [− 11.4, 4.2]	0.95	0.4 [− 5.2, 7.7]
2nd CNN initialization	0.74	25	0.87	− 4 [− 11.7, 3.9]	0.94	− 0.1 [− 5.1, 7]
3rd CNN initialization	0.59	24	0.89	− 3.8 [− 12.4, 5.3]	0.95	0 [− 6.7, 7.6]
Ensemble CNN	0.86	19	0.88	− 4.2 [− 10, 5.7]	0.94	− 0.4 [− 5.2, 7]
