An Ultrasound Scan (also known as a Sonogram) is a Clinical Investigation.

An Ultrasound Scan is a procedure that uses high frequency sound waves to create an image of part of the inside of the body, such as the heart.

Ultrasound Scans can be used:

• to help doctors make a diagnosis or to assess the effects of a treatment;
• to study blood flow and to detect any narrowing or blocking of blood vessels;
• during a Pregnancy Episode to produce images of the baby in the womb.
