Fig. 2From: Whole-heart four-dimensional flow can be acquired with preserved quality without respiratory gating, facilitating clinical use: a head-to-head comparisonStability of stroke volume (SV) over the experiment in healthy volunteers. The scatter plot (left) shows SV (ml) from 2D flow acquired before and after 4D flow acquisitions. The Bland-Altman analysis (right) shows bias (solid line) ±1.96SD (dashed lines). The SV did not vary significantly over the experimentBack to article page
