Of all of these uses, dating the pregnancy is the most common reason to use ultrasound, particularly when the expectant mother cannot remember the date of her last period (as in breast-feeding or irregular cycles).
Even when the last period is known, ultrasound is reassuring to demonstrate adequate growth, especially when there’s a risk of delayed growth, as in hypertension or smoking, or if there’s the risk of exaggerated growth, as in gestational diabetes.
Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.

Our ultrasounds are performed by licensed ultrasound technicians under the direction of obstetricians.
We can come along side you to give you the information you need about your pregnancy to make an informed and empowered decision about abortion.
Objective: To assist clinicians in assigning gestational age based on ultrasound biometry.
These measurements are computed automatically in the ultrasound machine’s software.
The software has certain measurement scales based on data from large populations, and your baby’s measurements are put into this scale.
