T2-based MR oximetry might allow the assessment of fetal oxygen saturation non-invasively which is important for high risk pregnancies. However, for practical application of this method to detect fetuses at risk, measurements have to be more accurate. Therefore technical difficulties due to the fetal model have to be improved.
