An Ultrasound (US) scan is a painless, radiation-free, medical examination which takes images of the body’s internal structures using high-frequency sound waves.
This technique has evolved substantially over recent years and modern equipment is capable of delivering very high standards of diagnostic imaging.
Medical ultrasound (also known as diagnostic sonography or ultrasonography) is a diagnostic imaging technique based on the application of ultrasound. It is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs. Its aim is often to find a source of a disease or to exclude pathology.
The advantages of US over other medical imaging are that it provides images in real-time, is portable and can be brought to the bedside. It is substantially lower in cost than other imaging modalities and does not use harmful ionizing radiation.
Ultrasound refers to sound waves with frequencies which are higher than those audible to humans (>20,000 Hz). Ultrasonic images, also known as sonograms, are made by sending pulses of ultrasound into tissue using a probe. Copies of these images can be made available to the client.
Many different types of images exist which can display blood flow, motion of tissue over time, the location of blood, the presence of specific molecules, the stiffness of tissue, or the anatomy of a three-dimensional region.
