Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing part of the body to high-frequency sound waves to produce images of organs within the body. As the name suggests, ultrasound scanning uses the principle of Sound Waves to produce images of the organs, thus no ionizing radiation (as is used in X-rays) is involved. Ultrasound images are captured in real-time, and they can show the structures and movement of the body’s internal organs, as well as blood flowing through blood vessels. Ultrasound imaging is a non-invasive medical test that helps physicians in the diagnosis and treatment of medical conditions.
Advancement in ultrasound technology has enabled a three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images as what is available in IJN. A Doppler ultrasound study may be part of an ultrasound examination to evaluate blood as it flows through a blood vessel, including the body’s major arteries and veins in the abdomen, arms, legs and neck.
