MVnet: automated time-resolved tracking of the mitral valve plane in CMR long-axis cine images with residual neural networks: a multi-center, multi-vendor study

Table 5 Automated and manual inter-observer spatial annotation agreement

Spatial agreement	n images	Euclidean distance error (mm)	Angular distance error (º)	MV displacement error (mm)
\({{\text{MVnet}}_{\text{Mixed}}}\)	5834	3.31 ± 2.55	3.69 ± 3.89	−0.10 ± 0.97
Inter-observer	2960	3.29 ± 2.90	4.05 ± 4.22	−0.15 ± 1.18

The mean error ± standard deviation are reported for Euclidean and angular distances, and mitral valve displacement error between ground-truth and automated (\({{\text{MVnet}}_{\text{Mixed}}}\)) or a pair of second observers manual annotations. MV mitral valve
