The cerebroplacental Doppler ratio revisited
Open accessAbstract
Objective: To evaluate the distribution of Doppler pulsatility index (PI) measurements of the umbilical and middle cerebral arteries in singleton fetuses of women with normal uterine artery blood flow and to construct reference ranges for the cerebroplacental PI Doppler ratio. Methods: The PI was determined in the mid‐portion of the umbilical artery and the mid‐ or distal segment of the middle cerebral artery in 306 normal singleton fetuses. The cerebroplacental Doppler ratio (CPR) was determined from paired measurements. After determination of the best fit, reference ranges were constructed for each parameter against gestational age (GA). Results: The PI for the umbilical artery had a linear relationship with GA (umbilical artery PI = − 0.0246 × GA + 1.7791, r2 = 0.4025, P < 0.001). The middle cerebral artery PI and the CPR both showed a quadratic relationship with GA (middle cerebral artery PI = − 0.0058 × GA 2 + 0.3335 × GA − 2.7317, r2 = 0.2365, P < 0.01), (CPR = − 0.0059 × GA 2 + 0.383 × GA − 4.0636, r2 = 0.2788, P < 0.001). Conclusion: The CPR is not constant throughout gestation. Reference ranges constructed by a standardized Doppler technique may be of benefit in the monitoring of high‐risk pregnancies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
