Ultrasound

Ultrasound (US) imaging is a method of obtaining images from inside the human body through the use of high frequency sound waves. The reflected sound wave echoes are recorded and displayed as a real-time visual image. No ionizing radiation (x-ray) is involved in ultrasound imaging. Obstetric ultrasound refers to the specialized use of sound waves to visualize and thus determine the condition of a pregnant woman and her embryo or fetus.

Ultrasound is a useful way of examining many of the body's internal organs, including the liver, gallbladder, spleen, pancreas, kidneys, and bladder. It’s also very useful in vascular imaging. Because ultrasound images are captured in real-time, they can show the movement of internal tissues and organs, and enable physicians to see blood flow.
