Table 4 Manual inter-observer clinical metric accuracy of mitral valve derived parameters

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

Clinical agreement n subjects Manual measures Observer 2 measures Error measures ICC (CI 95%)
MAPSE (mm) 50 11.1 ± 3.8 10.8 ± 3.9 −0.3 ± 1.2 0.95 (0.91–0.97)
