Evaluation of right ventricular volume and systolic function in normal fetuses using intelligent spatiotemporal image correlation

Table 1 The relationship between normal fetal right ventricular end-diastolic volume, right ventricular end-systolic volume, right stroke volume, right cardiac output, and right ejection fraction with gestational ages from 22 to 35⁺⁶ wk

Gestational age	REDV	RESV	RSV	RCO	REF
r	0.903	0.874	0.866	0.865	0.120
P	< 0.001	< 0.001	< 0.001	< 0.001	0.187

REDV: Right ventricular end-diastolic volume; RESV: Right ventricular end-systolic volume; RSV: Right stroke volume; RCO: Right cardiac output; REF: Right ejection fraction.
