What is an Ultrasound?
Ultrasound is an imaging technique using high frequency sound (high enough that it is not audible and is able to pass through the body) to produce anatomical images of the body. First gel is applied to the region of the body being scanned – this facilitates the transmission of sound waves into the body. Then sound waves then enter the body via a probe placed on the skin in a completely painless way. The sound is reflected or absorbed by tissues in the body differently (similar to sonar in a submarine) and its frequency changes as a result. The altered frequency of the reflected sound is recorded by the probe as an echo and an image is then generated which reflects the different parts of the anatomy.
Ultrasound involves no ionising radiation (unlike CT and radiographs) and can be used completely safely in pregnancy and young children. It has the advantage of providing live, real-time images allowing body parts to be assessed dynamically as they move/function.
When would we use an Ultrasound?
Ultrasound is used for diagnosis of a suspected problem either on its own, or as a complement to other imaging techniques. It can also be used to guide interventional procedures such as injections, nerve blocks, biopsies and more invasive surgery and ultrasound guidance provides a safer way to perform these procedures with a higher chance of success and less risk of complication. As there is no associated ionising radiation, it can be safely used in pregnancy.
What makes our Ultrasound beyond better?
At OneWelbeck, we use the latest state of the art ultrasound machines which allow high resolution, real-time imaging of the body allowing the most accurate diagnoses. Images can be saved as stills or video and are transferred to our digital Picture Archiving Communication System (PACS) allowing the images to be reviewed at the highest quality by anyone looking after you at any time.
