Summary table for the sample of 11 dogs.

Estimated volumes of the segmented structures from operators 1 and 2 (O1/O2), expressed as the volume averaged across the considered subjects, their standard deviation, and CV. For the ventricles, we report the values obtained from the automatic segmentation, since this outperformed the manual approach. The Dice similarity index shows a good agreement between the two operators, corresponding to an average Dice index of 0.75.
