12 week pregnancy dating scan: here’s what to expect

What to Expect During an Ultrasound Many people who hear the term ” ultrasound ” likely picture a pregnant woman in her doctor’s office getting a sneak peek of the baby growing inside her womb — perhaps even finding out whether she should paint the nursery pink or blue. But while fetal imaging is one of the most common uses of ultrasounds, this diagnostic tool actually has many applications. How Ultrasound Imaging Works Ultrasound, also called sonography, uses sound waves to develop ultrasound images of what’s going on inside the body. An instrument called a transducer emits high-frequency sound, inaudible to human ears, and then records the echoes as the sound waves bounce back to determine the size, shape, and consistency of soft tissues and organs. This information is relayed in real time to produce images on a computer screen. Ultrasound technicians, or sonographers, have special training in how to perform the test. Then a radiologist or your doctor will interpret the ultrasound images. This technology can help diagnose and treat certain conditions. Uses of Ultrasound Tests Ultrasound imaging has many uses in medicine, from confirming and dating a pregnancy to diagnosing certain conditions and guiding doctors through precise medical procedures.

Back to Health A-Z Ultrasound scan An ultrasound scan, sometimes called a sonogram, is a procedure that uses high-frequency sound waves to create an image of part of the inside of the body. You can’t hear these sound waves, but when they bounce off different parts of the body, they create “echoes” that are picked up by the probe and turned into a moving image. This image is displayed on a monitor while the scan is carried out.

Preparing for an ultrasound scan Before having some types of ultrasound scan, you may be asked to follow certain instructions to help improve the quality of the images produced. For example, you may be advised to: In some cases, you may also be given an injection of a harmless substance called a contrast agent before the scan, as this can make the images clearer.
