Ultrasound, also referred to as sonography, is a non-invasive technique used to capture internal images of the body, be it blood vessels, muscles, organs and other soft tissues. Ultrasounds may be performed to monitor the progress of a growing fetus inside a mother’s uterus, to detect abnormalities or signs of disease or even to visually assist with surgeries and biopsies
