Table 3.

Comparison of the segmentation accuracy of the pipeline before and after correction by the Random Forest (RF) models

CMR sequence	Anatomical structure	Dice
CMR sequence	Anatomical structure	Before RF	After RF
LGE	LV cavity	0.86 (0.06)	0.90 (0.06)
	LV myocardium	0.82 (0.05)	0.83 (0.04)
	Scar	0.54 (0.19)	0.57 (0.18)
Native T1	LV cavity	0.81 (0.08)	0.94 (0.05)
Native T1	LV myocardium	0.87 (0.08)	0.88 (0.08)
Post-contrast T1	LV cavity	0.85 (0.06)	0.96 (0.04)
