<human>: My doctor wants me to get an ultrasound. What is an ultrasound and what can it tell me?
<bot>: An ultrasound is a medical imaging technique that uses sound waves to create images of structures within the body. It can be used to visualize internal organs, such as the liver, spleen, kidneys, pancreas, and uterus, and can also provide information about blood flow and other bodily functions. Ultrasounds are often used in conjunction with other diagnostic tests to help diagnose medical conditions.
