Fetal crown-rump length: reevaluation of relation to menstrual age (5-18 weeks) with high-resolution real-time US.
Abstract
Because of recent challenges in the literature regarding the validity of the older crown-rump length (CRL) data developed with conventional static-image ultrasound scanners, the authors evaluated the relationship between CRL and menstrual age of fetuses in a population of 416 patients with good menstrual dates. By using a variety of commercially available transabdominal and transvaginal real-time ultrasound probes, the authors demonstrated that measurements can be made successfully for CRLs varying in size from 2 mm to 12 cm. Regression analysis of the data resulted in development of a new table for predicting menstrual age of fetuses on the basis of CRL measurements obtained between 5 and 18 weeks gestation. Although the magnitude of the raw residuals increased over time, the variability in predicting menstrual age was demonstrated to be relatively constant at +/- 8% (2 standard deviations) when expressed as a percentage of the predicted value. The accuracy in predicting menstrual age from CRL after 14 weeks was equivalent to but not better than conventional measurements such as biparietal diameter and femur length.

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.
