The : The ultrasound dating now is remarkably accurate. There can be discrepancies in the dates that the patient has from the date of menstrual period, but the ultrasound dating is remarkably accurate based on the "crown rump length" of the fetus, which is the measurement of the baby from the crown of the head to the tip of its bottom, the development of the heart, and other vital organ which can already be identified by ultrasound dating.
