Ultrasound imaging, or sonography, is a method of seeing inside the human body through the use of high-frequency sound waves. Ultrasound is a useful way of examining many of the body’s internal organs, including the heart, liver, gallbladder, spleen, pancreas, kidneys and bladder. Because ultrasound images are captured in real-time, they can show movement of internal tissues and organs. Many parents see the first picture of their unborn child with ultrasound examinations of the fetus.
Physicians also use ultrasound to evaluate breast abnormalities. Ultrasound helps detect some breast masses and is the best way to determine whether a cyst is present without drawing fluid from the area of concern.
