The crown-rump length (CRL) is a measurement of the embryo, usually identified at 6 to 7 weeks' gestation. 17, 48 The embryo is measured along its longest axis to obtain the CRL measurement (Fig. 2). Crown-rump length may be used to accurately date pregnancy between 7 and 13 weeks' gestation.

The CRL was measured to the nearest mm in a sagittal plane with the fetal head in a neutral position.Crown-rump length. Gestational age = 6 weeks plus (CRL x days). This relies on the growth of the normal fetus of 1 mm per day after the 6th week of gestation. For example, a CRL of 16 mm would correspond to a gestational age of 8 weeks and two days (6 weeks plus 16 days = 8 weeks and 2 days).Result(s): First-trimester pregnancy loss rates were significantly higher in pregnancies with mGSD - CRL <5 mm (43.7%) compared with 5-9.99 mm (15.8%), 10-14.99 mm (9.9%), and ≥15 mm (7.1%). No correlations were found with infant birth weight, gestational age at delivery, or other pregnancy complications. mGSD - CRL was not a better predictor ...The aim of this study was to evaluate the accuracy of gender assignment by transabdominal ultrasound in a large number of fetuses at 12-14 weeks' gestation, and to identify the crown-rump length (CRL) at which the accuracy level is high enough to make a definitive decision regarding invasive procedures in a fetus identified as female. MethodsA crown-rump length of 5 mm was widely recommended as a positivity criterion for diagnosing failed pregnancy when no cardiac activity is seen. Recent studies have shown that a 5-6 mm cutoff can result in a false positive diagnosis of pregnancy failure. It is now recommended that we use a 7 mm (rather than 5 mm) cut-off for diagnosing failed ...Getting the right fit for your shoes is essential for comfort and support when you’re on your feet.
