Ultrasound: sound, not radiation

The short answer

Ultrasound uses high-frequency sound waves to create live images. A sonographer moves a small handheld probe over the skin with a little gel to see organs, vessels and soft tissue in real time.

There is no radiation involved, and most examinations are quick and painless.

The best scan is the one that answers your clinician’s question with the least burden on you.

What it means for your visit

Preparation depends on the examination. For Ultrasound, the most important things are:

• Abdominal scans often need a few hours of fasting

• Pelvic scans often need a comfortably full bladder

• Wear two-piece clothing

Questions worth asking

• What is this examination looking for?

• Is there anything I should do — or avoid — beforehand?

• How will I receive the results, and who will explain them?
