Perfusion and apparent oxygenation in the human placenta (PERFOX).

A strength of the joint sequence is that it provides truly simultaneous and co-registered estimates of local and perfusion, however, to achieve this, the time per slice is prolonged compared to a perfusion only scan which can potentially limit coverage. The achieved interlocking can be particularly useful when quantifying transient physiological effects such as uterine contractions. PERFOX opens a new avenue to elucidate the relationship between maternal supply and oxygen uptake, both of which are central to placental function and dysfunction.
