An ultrasound is a test that uses sound waves to take pictures of organs and structures inside the body. It can show problems you can’t see with an 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 prepare for an ultrasound test

Instructions may vary depending on the type of ultrasound test you are having. The instructions below explain how to get ready for your ultrasound test so it can be done safely and correctly. Please read the instructions for your specific ultrasound test and follow them before your appointment.

Not all ultrasound tests require preparation. Refer to the no preparation patient instructions if you do not require preparation for your ultrasound test.

Some procedures use localization to help doctors find a specific area in your body before a biopsy, surgery, or treatment. If this applies to you, read the localization patient instruction.

Radiofrequency ablation uses heat to treat harmful tissue, like a small tumor. If you are having this treatment, read the radiofrequency ablation patient instructions.

Interventional ultrasound

An interventional ultrasound uses sound waves to let doctors see inside the 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.
