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.
How Should You Prepare for Ultrasound?
Your preparation instruction will vary based on the type of ultrasound you are having:
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.
