First-Trimester & Dating Scans
Early viability and gestational dating ultrasound confirming intrauterine pregnancy, fetal heartbeat, and accurate due date.
The First-Trimester Dating Scan—performed between 6 and 9 weeks of gestation—is the most reassuring initial milestone of your pregnancy. It serves to confirm that the embryo is safely implanted within the uterine cavity, rule out ectopic pregnancy, and check for the presence of a healthy fetal heartbeat.
By measuring the Crown-Rump Length (CRL), this scan offers the most accurate determination of gestational age and your Estimated Due Date (EDD). It also verifies whether you are carrying a single embryo or twins, establishing vital baseline information for all future clinical care.
