An ultrasound scan uses high-frequency sound waves to create images of the inside of the body. It is suitable for use during pregnancy.

Ultrasound scans, or sonography, are safe because they use sound waves or echoes to make an image, instead of radiation.

Ultrasound scans are used to evaluate fetal development, and they can detect problems in the liver, heart, kidney, or abdomen. They may also assist in performing certain types of biopsy.

The image produced is called a sonogram.

The person who performs an ultrasound scan is called a sonographer, but the images are interpreted by radiologists, cardiologists, or other specialists.

The sonographer usually holds a transducer, a hand-held device, like a wand, which is placed on the patient’s skin.
