Figure 2From: Automatic multi-vessel volume flow calculation with 4D flow CMRRegression analysis of (A) manual vs. automatic volume flows in the proximal ascending aorta, and (B) automatically measured volume flows in the pulmonary trunk vs. proximal ascending aorta (Qp/Qs). Both comparisons yielded very strong correlation: R2 = 0.927 and R2 = 0.972, respectively (p < 0.001 in both cases).Back to article page
