Non‐invasive evaluation of blood oxygen saturation and hematocrit from <i>T</i>_<i>1</i> and <i>T</i>_<i>2</i> relaxation times: In‐vitro validation in fetal blood

Results demonstrate accurate quantification of Hct and sO₂ from T₁ and T₂ . This method is applicable to noninvasive fetal vessel oximetry-an application where existing oximetry devices are unusable or require risky blood-sampling procedures.
