How Does an Ultrasound Work?

If you’ve never had an ultrasound before, you may be wondering what actually happens during the exam. How does it create an image of your pregnancy, and what can you expect when you have one?

An ultrasound uses sound waves to create images of structures inside the body. This technology can help you gather important information about how the pregnancy is developing.

At The Cline Center, we provide free, confidential pregnancy testing and limited ultrasounds to help you get the information you need. Whether you’ve only just found out you are pregnant or are considering your next steps, we are here to help you.

Contact us to make your appointment, and read on to understand how an ultrasound works and what to expect when you come in for one at our center. 

Ultrasound Technology Explained

An ultrasound uses a device called a transducer to send high-frequency sound waves into the body. When the waves encounter different tissues and structures, they bounce back as echoes.

The transducer receives these echoes and sends information to a computer, which creates an image that can be viewed on a screen.

Unlike an X-ray, an ultrasound does not use radiation. During pregnancy, ultrasound can be used to look at the uterus and developing pregnancy and gather information about the gestational age, pregnancy location, and signs of viability. 

The Different Kinds of Ultrasounds

The type of ultrasound performed depends on what information is needed and the stage of pregnancy. 

The two common types of ultrasounds are:

• An abdominal ultrasound, which uses a handheld transducer that moves across the abdomen. A clear gel is placed on the skin to help the transducer send and receive sound waves.
• A transvaginal ultrasound uses a specially designed transducer that is gently inserted into the vagina. This approach can provide clearer images in early pregnancy because the transducer is closer to the uterus.

What an Ultrasound Can Show You

A positive pregnancy test result shows that hCG is in your body, but the test cannot tell you how far along you are, where the pregnancy has implanted, or whether the pregnancy is developing.

A limited ultrasound can provide these details and may identify concerns such as an ectopic pregnancy or signs that a miscarriage has occurred.

Limited ultrasounds at our center are performed by our nurses and sonographers who will walk you through each step, explain what you’re seeing, and answer your questions along the way.
