What is the Primary Source of Discordance in Strain Measurement Between Vendors: Imaging or Analysis?

Abstract Strain imaging quantifies myocardial deformation in both overt and subclinical myocardial diseases. Strain values have been shown to vary between vendors. The aim of this study was to investigate whether this variation reflects differences of image characteristics or analysis software. We e...
