Table 5 Automated and manual inter-observer spatial annotation agreement

From: 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

Spatial agreement n images Euclidean distance error (mm) Angular distance error (º) MV displacement error (mm)
