Overall, this model can correctly classify 94.9% of the groups. We determined threshold values for MGSD-CRL (≥10 mm) and P (≥25 ng/mL) to predict abortion, but not for FHR. Interestingly, 14 patients with FHR ≥ 175 beats/min did not abort.fetal pole may be identifiable on endovaginal ultrasound (1-2 mm) fetal heart rate ( FHR) should be ~100-115 bpm. gestational sac should be ~10 mm in diameter. 6.5 weeks. crown rump length ( CRL) should be ~5 mm. 7-8 weeks. CRL is between 11-16 mm. cephalad and caudal poles can be identified. 8-9 weeks.Furthermore, as we try to correlate early embryonic size with gestational age, we realize that the crown-rump measurement is not applicable in principle or in nomenclature when the embryo is less than 18 mm long. When first seen, the embryo is relatively straight; a measurement of its size is best described as "greatest length."
