What is the difference between a sonogram and an ultrasound?

An ultrasound and a sonogram are related, though they are different.

Ultrasound is a type of medical imaging that uses high-frequency sound waves to create images of internal organs and structures in the body. An ultrasound machine emits sound waves that bounce off the tissues and organs inside the body, creating echoes that are recorded and processed into images. Ultrasound imaging can visualize the structure and function of various organs, such as the heart, liver, kidneys, and reproductive organs.

On the other hand, a sonogram is the resulting image produced by ultrasound. It visually represents the internal structures imaged with the ultrasound machine. The term "sonogram" is often used interchangeably with "ultrasound," but technically, a sonogram is the resulting image or picture, while an ultrasound is the actual procedure that produces the image.
