Learn how ultrasound examinations work, common scan types and why preparation differs by examination. A practical patient guide. This guide explains the basics and helps you prepare sensible questions for your healthcare team.
What is an ultrasound scan?
Ultrasound uses high-frequency sound waves to form images of tissues and organs. A handheld transducer sends and receives sound waves, and a computer creates images. It does not use the ionising radiation used in X-ray imaging.
Individual circumstances differ. Always follow your referring clinician’s advice and confirm test-specific instructions with the centre before visiting.
What are the common types?
Abdominal ultrasound may examine organs such as the liver or kidneys. Pelvic ultrasound may assess structures in the pelvis. Pregnancy ultrasound is used when medically indicated during pregnancy. Vascular Doppler studies provide information about blood flow.
Individual circumstances differ. Always follow your referring clinician’s advice and confirm test-specific instructions with the centre before visiting.
How should you prepare?
Preparation depends on the body part and the clinical indication. Some abdominal examinations require fasting; some pelvic scans require a full bladder. Do not assume the same instructions apply to every ultrasound. Confirm with the imaging team.
Individual circumstances differ. Always follow your referring clinician’s advice and confirm test-specific instructions with the centre before visiting.
What happens during the scan?
A sonographer or medical professional applies gel and moves a transducer over the area. Some examinations may require repositioning or specialized techniques. Duration and reporting arrangements vary.
Individual circumstances differ. Always follow your referring clinician’s advice and confirm test-specific instructions with the centre before visiting.
When will results be available?
Ask the centre about report collection and whether you should return to the referring clinician. An ultrasound result should be interpreted with symptoms, medical history and other findings.
Individual circumstances differ. Always follow your referring clinician’s advice and confirm test-specific instructions with the centre before visiting.
