Does 3D myocardial strain quantification differ from 2D myocardial strain quantification in healthy fetuses?
Discrepancies between 2D and 3D fetal cardiac strain measurements are driven by out-of-plane motions and timing mismatches, highlighting inaccuracies in 2D strain and the need for standardization.
