Ultrasound Scanning, also called “ultrasound imaging” or “sonography” uses high frequency radio waves to produce images of the body. Ultrasound does not use ionizing radiation. Ultrasound images are captured in real time and show the structure and movement of the body’s internal organs, as well as blood flowing through arteries and veins. Ultrasound imaging helps physicians diagnose medical conditions such as those involving the liver, gallbladder, pancreas, spleen, kidneys, bladder, uterus, ovaries and testicles.
