What is a liver ultrasound?

Here, highly experienced consultant radiologist, Dr Thaj Rehman, tells us all about liver ultrasounds, including when they are typically recommended for patients. 

What is a liver ultrasound?

A liver ultrasound is a non-invasive imaging technique used to examine the liver and its surrounding structures. This test, also known as an abdominal ultrasound, provides detailed images of the liver by using high-frequency sound waves. Liver ultrasounds are commonly used to detect liver diseases, assess abnormalities, and monitor existing conditions.

When are they recommended?

Liver ultrasounds are often recommended when patients exhibit symptoms of liver problems, such as abdominal pain, jaundice, or unexplained weight loss. It is also used in people with risk factors for liver disease, including those with a history of hepatitis, alcohol abuse, or fatty liver disease.

The procedure can detect a wide range of liver conditions, including liver cirrhosis, tumors, cysts, gallstones, fatty liver disease, and liver cancer. Additionally, liver ultrasounds can monitor changes in liver size or structure in chronic liver diseases, allowing for early intervention if conditions worsen.

The procedure

During the procedure, a technician applies gel to the patient’s abdomen and uses a transducer (a handheld device) to capture images of the liver. The transducer emits sound waves that bounce off the liver and create a visual image on a monitor.

The process is painless, and it typically takes less than 30 minutes to complete. The patient may be asked to fast before the exam to enhance the accuracy of the images, as an empty stomach can reduce gas in the abdomen, providing clearer visuals of the liver.

Advantages

One of the primary advantages of liver ultrasound is that it is non-invasive, safe, and does not use radiation, making it suitable for frequent use. Unlike CT scans or MRIs, it poses no risk of exposure to radiation, which is beneficial for patients who require regular monitoring of their liver health.

In conclusion, a liver ultrasound is an essential diagnostic tool that helps physicians assess liver function, detect early signs of liver disease, and make informed decisions about treatment. Regular liver monitoring, especially for individuals at risk, is critical to maintaining overall liver health and preventing complications.
