Sonography

Medical ultrasound (also known as diagnostic sonography or ultrasonography) is a diagnostic imaging technique based on the application of ultrasound. It is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs. Its aim is often to find a source of a disease or to exclude pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and was an early development and application of clinical ultrasonography. Ultrasound refers to sound waves with frequencies which are higher than those audible to humans (>20,000 Hz).

Ultrasonic images, also known as sonograms, are made by sending pulses of ultrasound into tissue using a probe. The ultrasound pulses echo off tissues with different reflection properties and are recorded and displayed as an image.

Ultrasound imaging uses sound waves to produce pictures of the inside of the body. It is used to help diagnose the causes of pain, swelling and infection in the body’s internal organs and to examine a baby in pregnant women and the brain and hips in infants. Ultrasound is a useful way of examining many of the body’s internal organs, including but not limited to the heart and blood vessels, including the abdominal aorta and its major branches liver gallbladder spleen pancreas kidneys bladder uterus, varies, and unborn child (fetus) in pregnant patients eyes thyroid and parathyroid glands scrotum (testicles) brain in infants hips in infants spine in infants.
