Cada máquina faz um strain diferente?

The clinical implications of these discrepancies are significant. Although ‘global longitudinal’ strain appears to be comparable, at the current stage of development, ‘global radial/circumferential’ and ‘regional’ strain calculations should not be considered to be transportable between vendors. Therefore, if strain is being used in longitudinal follow-up, baseline and follow-up images need to be obtained using the same system.
