Human observer assessment of motion extent (%) on 200 T1 maps before motion correction, and after the baseline and proposed method (MOCOnet) for motion correction.

	All data (N = 200)	Group 1 (N = 50) Severe motion	Group 2 (N = 100) Moderate motion	Group 3 (N = 50) Mild to no motion
Before MOCO	37.1 ± 21.5	55.8 ± 18.7 (99.3)	35.5 ± 18.9 (80.5)	21.7 ± 13.8 (62.1)
Baseline method	15.8 ± 15.6	25.8 ± 19.8 (93.4)	14.7 ± 13.9 (65.7)	8.1 ± 6.5 (34.2)
MOCOnet	13.3 ± 10.5	18.6 ± 14.3 (86.9)	12.7 ± 9.2 (46.4)	9.4 ± 6.4 (19.8)

The quality scores are inverse variance-weighted scores of three human observers and reported in mean ± SD (maximum value). The best results are highlighted in bold.
