Ultrasound
Ultrasound imaging or sonography is a safe exam that uses high-frequency sound waves to create real-time images of the body. It is most commonly known for its use during pregnancy.
Ultrasound imaging works by sending sound waves into the body. These waves are able to pass through softer tissue but are reflected by more dense tissue and bone. These reflected or echoed sound waves are used to create a live image of what is going on inside the body that includes details such as movement and even a fetal heartbeat.
Who are ultrasounds for?

- A light breakfast is allowed before afternoon appointments. This can include dry toast, black coffee, tea, or clear broth.
- Do not eat or drink any dairy product, fats, cream or oils before your ultrasound.

What is an ultrasound like?
During an ultrasound, a technologist will use lubricating gel on the area to be scanned; she will then place a handheld transducer over the gel and move as needed to produce a clear image on the nearby display. It is an extremely simple and pain-free process. An internal ultrasound requires placing the transducer in the vagina.
Is there a weight limit?
