Determination of Qp/Qs using MRvenc in infants and children suffering from VSDs is quick, safe and reliable compared with invasive oximetry. MRvenc under free breathing conditions generates more physiological data as compared with breath holding. Even in small children with high respiratory frequencies motion artefacts were not detectable.
