Your guide to Ultrasound
Real time views of organs and soft tissues. What to expect, how to prepare and what to ask before booking.
Last reviewed 7 Oct 2026 · Information onlyWhat is it?
Ultrasound uses sound waves to create moving images. It does not use ionising radiation.
What is it used for?
It can examine abdominal and pelvic organs, some joints, blood flow and other soft tissues. It cannot see every structure clearly, and suitability depends on the clinical question.
How does it feel and how long does it take?
Gel is placed on the skin and a small probe is moved over the area. Most scans take 15 to 45 minutes. Some pelvic scans use an internal probe, with your consent.
How should I prepare?
Some scans need a full bladder; others need fasting. Ask for instructions for your scan. You can ask about a chaperone for an intimate examination.
Who needs extra safety checks?
External ultrasound has no known risks from the sound waves used. Internal examinations may be uncomfortable and are optional. Tell the team about latex allergies or discomfort.
A scan is not a substitute for clinical assessment. A normal result does not rule out every condition. Partner clinics include a clinician or GP call before the scan to confirm the right test.
