Ultrasound examinations use high-frequency sound waves that are reflected from different soft tissue, structures or organs in different ways, producing an image which is displayed on a screen.
Ultrasound is painless, and as it does not use radiation, it is very safe for the patient. It produces very detailed images, and can be carried out while there is movement, so it is particular useful for imaging of babies and children.
It is often used in pregnancy, to monitor how the foetus is developing in the womb, but is also employed to investigate a number of conditions in an adult patient. High resolution ultrasound can give useful information about how the blood flows through arteries and veins, can evaluate the musculoskeletal system, and examine lumps in areas like the breast, often eliminating the need for more invasive and expensive tests.
Ultrasound can also be used to guide the Radiologist when performing biopsies or pain management injections.
