Standardisation of crown-rump length measurement.
Correct estimation of gestational age is essential for any study of ultrasound biometry and for everyday clinical practice. However, inconsistency in pregnancy dating may occur through differences in measurement methods or errors during measurement. In the INTERGROWTH-21(st) Project, pregnancies are dated by the last menstrual period, provided that it is certain and associated with a regular me...
متن کاملAutomatic Gestational Age Estimation Based on Crown Rump Length and Gestational Sac
The development of ultrasound technology allows us to see the structure and development of the fetus directly. Crown-Rump Length (CRL) and mean diameter of gestational sac (MSD) can be used to determine the age of the fetus. Both parameters are useful for measuring different aspects of the first trimester of pregnancy. This study proposes a method to obtain those parameter values automatically ...
متن کاملCorrelation between the Fetal Liver Length and Crown- Rump Length During the First Trimester Screening

متن کاملNew first-trimester crown-rump length equations from a French general population.
INTRODUCTION The purpose of this study was to obtain precise knowledge of fetal biometric measurements, in particular crown-rump length (CRL). Our results have been carefully compared to equations found in the literature. MATERIALS AND METHODS Single-operator measurements of 2,123 spontaneous pregnancies from a general French population provided new statistical relationships between fetal age...
متن کاملTeratological Effects of Chlorpyrifos on Crown Rump Length and Weight of Developing Mice
An organophosphorus insecticide, chlorpyrifos was tested for the embryotoxicity and teratogenecity in mice. Different sublethal doses of the insecticide i.e. 20, 40, 60 and 80ug/gm body weight were prepared by dissolving it in corn oil in such a way that each 0.1ml of the solution contains desired concentration. The doses were given orally on day 6 of gestation to different experimental groups....
