Fetal heart beat can be detected as early as 34 days (just under 6 weeks) gestation on good quality, high frequency transvaginal ultrasound, as a crown rump length (CRL) of as little as 1-2 mm. If a fetal heartbeat cannot be identified with a CRL ≥7 mm using transvaginal scanning, then embryonal demise can be diagnosed 3,4. Demise can be ...The fetal pole is usually identified at ~6.5 weeks with transabdominal ultrasound imaging and at ~6 weeks 2 with transvaginal ultrasound imaging, although it may not be seen until ~9 weeks in some cases. a fetal pole should be seen when MSD ≥16 mm on TVS (by RCOG criteria), or MSD ≥25 mm on TAS. pregnancy failure is not diagnosed …CRL (short for Crown Rump Length) is an index measured in mm, showing the length of the fetus from head to bottom. The doctor will use this index to assess the growth rate of the fetus in the mother's womb through ultrasound processes.

Weekly crown-rump length (CRL) measurements were taken between 7 and 14 weeks of gestation; the biparietal diameter (BPD) of the fetal head was measured once every 2-4 weeks from 13 to 30 weeks of gestation. Data were compared to those of a control group and to control data published in the literature.The normal crown-rump length of a fetus is 15mm. The CRL can also help identify growth retardation. A decrease in CRL Mean in Pregnancy may signal chromosomal abnormalities or growth restriction. In all fetuses the crown-rump length (CRL) was measured and the genital area of the fetus was examined in the mid-sagittal plane. The result of ultrasound examination was compared to the phenotypic sex of the newborn after delivery. Results: The feasibility as well as accuracy in determining gender increased with growing fetal CRL. At CRL < 50 ...
