Ultrasound
Ecografía
Also: Ultrasonido (regional variant)
What it means
An ultrasound is an imaging test that uses sound waves to make pictures, also known as a sonogram, of organs, tissues, and other structures inside the body. It allows a health care provider to see into the body without surgery. Ultrasound can help monitor the health and development of a fetus during pregnancy, diagnose the cause of a wide variety of medical conditions, and guide certain biopsy procedures. During most exams, a sonographer spreads a special gel on the skin and moves a wand-like device, called a transducer, across it. The device sends sound waves into the body, picks up the echoes, and turns them into images on a computer screen. Ultrasound doesn't use ionizing radiation like x-rays use. It is also called ultrasonography.
