Ultrasound
What is ultrasound?
Ultrasound is the use of high frequency sound waves to create an image of the inside of the body. This is done by using a small hand sensor and gel, which is moved over the surface of the skin and uses the sound waves to create a picture.
What happens during an ultrasound?
A small hand held device called a transducer is gently moved over your skin to examine the area indicated.
This is completely pain free.
A clear gel is used between the transducer and your skin. You may be asked to roll on to one side, to take a deep breath or to hold your breath to help get clearer images.
An ultrasound scan may take between 10 and 30 minutes depending on the information required by your doctor.
Preparation for the scan
Depending on the area been examined and information required some scans do not require preparation but for others it is important to follow the instructions in the letter.
Please check your appointment letter for the department your scan is being performed in and any preparation required for your scan.
