Ultrasound imaging, also called ultrasound scanning or sonography, is a method of obtaining images from inside the human body using high-frequency sound waves. The reflected sound wave echoes are recorded and displayed as a real-time visual image on a computer screen. No ionizing radiation (X-ray) is involved in ultrasound imaging. Obstetric ultrasound refers to the specialized use of sound waves to visualize and determine the condition of a pregnant woman and her fetus.
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, and enable physicians to see blood flow and heart valve functions. This can help us diagnose a variety of heart conditions and assess damage after a heart attack or other illness.
