"A sonogram, also known as an ultrasound, is a non-invasive medical imaging technique that uses high-frequency sound waves to create images of internal structures in the body. It is commonly used during pregnancy to monitor fetal development but can also be used to diagnose medical conditions in other parts of the body. During a sonogram, a technician applies a special gel to the skin and uses a handheld device to capture the sound waves as they bounce off internal organs or tissues. "
