Ultrasound of Hepatic - Liver Steatosis

What Is a Liver Steatosis Ultrasound?

A liver steatosis ultrasound is a non-invasive imaging test that uses high-frequency sound waves to generate real-time, detailed images of your liver, the largest organ in your gastrointestinal system. The test is specifically designed to detect and quantify excess fat buildup in liver cells, a condition called hepatic steatosis, which can range from mild to severe and may lead to long-term liver damage if left unmanaged. Unlike other imaging tests, this exam does not use ionizing radiation or intravenous contrast dye, so it carries no radiation exposure risk and is safe for patients of all ages, including those who are pregnant or have reduced kidney function.

Clinical Uses for Gastrointestinal System Evaluation

Your healthcare provider may order this exam to evaluate abnormal liver function test results that may indicate liver stress or damage, diagnose non-alcoholic fatty liver disease (NAFLD), alcoholic fatty liver disease, or other forms of hepatic steatosis, and monitor the progression of known fatty liver disease over time. It is also used to assess liver health in patients with gastrointestinal system risk factors including obesity, type 2 diabetes, high cholesterol, metabolic syndrome, or a history of heavy alcohol use, and to rule out other liver abnormalities that may be causing gastrointestinal symptoms such as upper right abdominal pain, bloating, fatigue, or nausea.

How to Prepare for Your Exam

You will need to fast for 6 full hours before your scheduled appointment, which means you cannot eat any food, drink any liquids (including water, coffee, tea, or sugary beverages), or chew gum during this window. Fasting ensures your stomach and gallbladder are completely empty, which eliminates obstructions that could block clear views of your liver during imaging. Wear loose, comfortable clothing that is easy to move, and avoid wearing jewelry or clothing with metal fasteners around your upper abdomen to ensure the technologist can easily access the area being imaged.

What to Expect During the Exam

The exam takes approximately 30 minutes to complete, and there is no claustrophobia risk, as you will not be enclosed in a narrow, enclosed machine at any point during the test. You will lie flat on a padded exam table while a water-based, hypoallergenic gel is applied to your upper abdomen; this gel helps the small handheld ultrasound transducer glide smoothly over your skin and captures clear sound wave signals to produce images of your liver. The technologist will press the transducer gently against different areas of your upper abdomen to capture multiple views of your liver; you may feel mild, temporary pressure, but the exam is completely painless and does not require any needles or incisions.

After Your Exam

There are no post-exam restrictions, so you can eat, drink, and resume all of your normal activities immediately after the test is complete. A board-certified radiologist will review all of your ultrasound images and write a detailed report that will be sent to your ordering healthcare provider, typically within a few business days. Your provider will discuss the results with you at a follow-up appointment, and if hepatic steatosis is confirmed, they will work with you to develop a care plan that may include lifestyle changes, additional testing, or treatment to protect your liver health.
