Table 3 Automated 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 Automated measures Error measures ICC (CI 95%)
MAPSE (mm) 143 12.3 ± 4.0 12.1 ± 3.9 −0.2 ± 1.3 0.94 (0.92–0.96)
