May support PC-MRI as noninvasive Qp/Qs alternative in pediatric CHD; leaves open prospective validation for clinical precision.
Does phase-contrast cine MRI accurately quantify left-to-right shunt (Qp/Qs) compared to oximetry in pediatric patients with congenital heart disease?
Phase-contrast cine MRI is a reliable and noninvasive alternative to oximetry for quantifying Qp/Qs in children with congenital heart disease, although direct through-plane measurement of atrial septal defects is inaccurate.
Beerbaum et al. (2001) studied this question.
