Liver ultrasound scan

Ultrasound scans use high frequency sound waves to create a picture of a part of the body.

They can show up changes, including abnormal growths. You might have one to diagnose a cancer or find out if it has spread.

You usually have them in the hospital x-ray department.

Preparing for your scan

Check your appointment letter for any instructions about how to prepare for your scan.

You might need to stop eating for 6 hours beforehand. Let the scan team know if this will be a problem for any reason, for example if you are diabetic.

Take your medicines as normal unless your doctor tells you otherwise.

What to expect

When you arrive at the clinic you might need to take off your upper clothing and put on a hospital gown. You lie on a couch.

During the scan

The sonographer puts a cold lubricating gel over your tummy (abdomen). Then they put the handheld probe on your skin.

They move the probe over your skin. You might feel a little pressure at times. Tell them if it is uncomfortable.

The ultrasound scanner has a microphone that gives off sound waves. The sound waves bounce off the organs inside your body, and the microphone picks them up. The microphone links to a computer that turns the sound waves into a picture on the screen.

Ultrasound scans are completely painless. You usually have the scan in the hospital x-ray department by a sonographer. A sonographer is a trained professional who is specialised in ultrasound scanning.

What happens afterwards

You can eat and drink normally after the test. You can go straight home or back to work afterwards.

Possible risks

Ultrasound scans are a very safe procedure. It doesn’t involve radiation and there are usually no side effects.

Getting your results

You should get your results within 1 or 2 weeks at a follow up appointment.

Waiting for test results can be a worrying time. You can contact your specialist nurse if you’re finding it hard to cope. It can also help to talk to a close friend or relative about how you feel.
