    • Fetal size in the second trimester is associated with the duration of pregnancy, small fetuses having longer pregnancies 

      Wilsgaard, Tom; Johnsen, Synnøve L.; Rasmussen, Svein; Hanson, Mark A.; Godfrey, Keith M.; Kiserud, Torvid (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-07-16)
      Background: Conventionally, the pregnancy duration is accepted to be 280–282 days. Fetuses determined by ultrasound biometry to be small in early pregnancy, have an increased risk of premature birth. We speculate that the higher rate of preterm delivery in such small fetuses represents a pathological outcome not applicable to physiological pregnancies. Here we test the hypothesis that in ...

    • Sex-specific reference ranges of cerebroplacental and umbilicocerebral ratios: A longitudinal study 

      Acharya, Ganesh; Ebbing, Cathrine; Karlsen, Henriette Odland; Kiserud, Torvid; Rasmussen, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-10)
      <p><i>Objectives - </i>The ratio of middle cerebral artery (MCA) pulsatility index (PI) to umbilical artery (UA) PI, i.e. cerebro‐placental ratio (CPR), has been suggested as a measure of fetal “brain sparing” phenomenon reflecting redistribution of fetal cardiac output as a response to placental insufficiency. Observational studies have shown that low CPR values predict increased risk of adverse ...
