Table 2. Comparisons and Correlations between Arterial Flow Volume Measured by Phase-Contrast MRI and Stroke Volume Calculated from Ventricular Volumes.

Arterial Flow Volume (mL)		Ventricular Stroke Volume (mL)		Paired t Test	Pearson Correlation
Ascending aorta (n = 109)	62.2 ± 18.9	2D short-axis cine LV	70.9 ± 20.6	p < 0.001	r = 0.90, p < 0.0001
		3D whole-heart LV	62.2 ± 19.9	p = 0.982	r = 0.85, p < 0.0001
Pulmonary artery (n = 77)	102.7 ± 30.9	2D short-axis cine RV	102.3 ± 31.9	p = 0.83	r = 0.90, p < 0.0001
		3D whole-heart RV	80.0 ± 34.9	p < 0.001	r = 0.77, p < 0.0001
