Imaging Tests

Ultrasound (US)

An ultrasound test uses sound waves to take pictures of organs and structures inside your body. It can show problems you can’t see with x-ray, magnetic resonance imaging (MRI), computed tomography (CT), or other imaging tests.

Ultrasounds can also be used to assist other procedures, this is called an interventional ultrasound.

How to get ready for your ultrasound test

Not all ultrasound tests need you to do anything special to get ready. Refer to the no preparation patient instructions if you’ve been told your ultrasound doesn’t need preparation.

Instructions may vary depending on the type of ultrasound test you’re having. The instructions below explain how to get ready for your ultrasound test so it can be done safely and correctly.

Follow the instructions for your specific ultrasound test carefully. If you have questions about the information on how to get ready for your test, call the imaging department where you are having your test.

Abdomen and pelvis

Bladder and kidney

Pregnancy and reproductive system

Rectum

Veins and arteries

Localization with ultrasound uses dye injected into your vein or an instrument of some kind to help your doctors find a specific area in your body. This is often done before a biopsy, surgery, or treatment and is called localization. If this applies to the ultrasound you’re having, read the localization patient instruction.

Radiofrequency ablation uses and electric current to create heat to treat harmful tissue, like a small growth or tumour. If you are having this treatment, read the radiofrequency ablation patient instructions.

Interventional ultrasound

An interventional ultrasound uses sound waves to let your doctor see inside your body while they treat a problem. It helps guide a small needle or tool to the right spot for things like taking a sample, draining fluid, or giving medicine. This method is safe, quick, and usually does not require surgery.
