My doctor wants me to get an ultrasound. What is an ultrasound and what can it tell me?

An ultrasound is a diagnostic imaging technique that uses high-frequency sound waves to create images of the internal organs and structures of the body. It can be used to visualize the size, shape, and position of various parts of the body, as well as detect any abnormalities or disease processes. Ultrasounds are often used in conjunction with other medical tests to provide more detailed information about the patient's condition.
