Abdominal ultrasound is an type of imaging test. It is used to examine organs in the abdomen including the liver, gallbladder, spleen, pancreas, and kidneys. The blood vessels that lead to some of these organs can also be looked at with ultrasound.

Alternative Names

Ultrasound – abdomen; Abdominal sonogram

How the test is performed

An ultrasound machine makes images of organs and structures inside the body.  The machine sends out high-frequency sound waves that reflect off body structures.  A computer receives these waves and uses them to create a picture. Unlike with x-rays or CT scans, this test does not expose you to ionizing radiation.

You will be lying down for the procedure. A clear, water-based conducting gel is applied to the skin over the abdomen. This helps with the transmission of the sound waves. A handheld probe called a transducer is then moved over the abdomen.

You may need to change position so that the healthcare provider can look at different areas. You may also need to hold your breath for short periods during the exam.

Most of the time, the test takes less than 30 minutes.

How to prepare for the test

Preparation steps vary depending on the problem. Most of the time, people are asked not to eat or drink for several hours before the exam. Your healthcare provider will go over what you need to do. 

How the test will feel

There is little discomfort. The conducting gel may feel a little cold and wet.
