Liver Awareness Month: What a FibroScan Can Show
How this noninvasive liver test measures stiffness and fat and helps doctors learn more about liver health.
October is National Liver Awareness Month, making it a good time to learn a little more about an organ most of us rarely think about until something goes wrong. The liver helps process nutrients, remove substances from the blood, store energy, and perform many other essential jobs.
One challenge with liver health is that chronic liver disease can sometimes progress without obvious symptoms. That makes the information gathered through medical history, blood work, imaging, and other testing especially important when a doctor has reason to look more closely.
One test you may hear about is FibroScan. This noninvasive exam gives doctors information about two important aspects of liver health: stiffness and fat buildup.
What Is a FibroScan?
FibroScan is a type of liver elastography. It uses ultrasound-based technology to measure physical properties of liver tissue without surgery, needles, or sedation.
The test provides information about:
- Liver stiffness, which can be associated with fibrosis or scarring
- Fat buildup in the liver, also called steatosis
Those measurements give your healthcare provider another piece of information to consider when evaluating liver health.
What Does Liver Stiffness Mean?
When the liver is injured repeatedly or over a long period of time, scar tissue can develop. This process is called fibrosis.
As fibrosis becomes more advanced, liver tissue may become stiffer. FibroScan measures that stiffness so your doctor can better understand whether scarring may be present and how significant it could be.
The measurement does not stand on its own. Liver stiffness can be affected by the underlying liver condition and other factors, so your healthcare provider interprets the result alongside the rest of your medical information.
What Can FibroScan Tell Doctors About Liver Fat?
FibroScan can also provide information about fat within the liver using a measurement known as the Controlled Attenuation Parameter, or CAP.
Too much fat in the liver is known as steatosis. You may also hear the broader term steatotic liver disease. One common form is metabolic dysfunction-associated steatotic liver disease, or MASLD, which is the newer name for what was previously called nonalcoholic fatty liver disease.
You do not need to memorize CAP numbers or try to interpret the result yourself. Your provider can explain what the measurement means in the context of your health and why it matters.
Why Might Your Doctor Recommend a FibroScan?
A FibroScan may be recommended when your doctor wants more information about possible liver fibrosis or fat buildup.
ImageCare notes that liver elastography may be used in the evaluation of chronic liver conditions including:
- Hepatitis B
- Hepatitis C
- Cirrhosis
- Autoimmune hepatitis
- Alcohol-associated liver disease
Certain inherited liver disorders, including hemochromatosis and Wilson disease
Steatotic liver disease and related liver inflammation
The reason for testing will depend on your medical history, laboratory results, symptoms, and other risk factors.
Can FibroScan Diagnose Liver Disease?
FibroScan can provide valuable information, but it does not diagnose every liver condition by itself.
Your doctor may also consider blood tests, medical history, other imaging exams, physical findings, and sometimes additional procedures. FibroScan measurements are meant to be interpreted within that larger clinical picture.
This matters because two people with similar measurements may not necessarily have the same underlying liver condition or need the same next steps.
Is FibroScan the Same as a Liver Ultrasound?
They are related, but they answer different questions.
A conventional liver ultrasound creates images that allow doctors to look at the liver’s appearance and surrounding structures.
FibroScan uses specialized elastography technology to measure properties of the liver tissue, particularly stiffness and fat. It does not simply provide the same type of pictures as a standard abdominal ultrasound.
Your provider may recommend one or both depending on what they are trying to learn.
Can FibroScan Replace a Liver Biopsy?
FibroScan has reduced the need for liver biopsy in some situations because it can provide information about fibrosis without removing a tissue sample. ImageCare describes the exam as a nonsurgical option for assessing liver damage.
That does not mean biopsy is never necessary. There are situations where a tissue sample may still provide information that FibroScan or other noninvasive tests cannot.
Your healthcare provider decides which approach makes sense based on the clinical question and the information already available.
What Happens During a FibroScan?
The exam itself is fairly simple.
At ImageCare, patients lie on their back with the right arm raised so the liver area can be accessed. A provider places water-based gel on the skin and holds a noninvasive probe over the liver. You may notice a slight vibration at the tip of the probe while measurements are collected. No sedation is required.
ImageCare also recommends wearing loose-fitting clothing and bringing your identification, insurance information, and a current medication list. Follow any instructions you receive for your specific appointment.
What Do FibroScan Results Mean?
Your FibroScan report typically gives your provider information about two areas.
The liver stiffness measurement helps assess possible fibrosis. The CAP measurement provides information about fat in the liver.
It can be tempting to search for a chart online and compare your numbers, but liver stiffness ranges are not interpreted exactly the same way for every liver disease. Other health factors can also affect the results. Your physician is in the best position to explain what your measurements mean for you.
What Happens If the Results Are Abnormal?
An abnormal FibroScan result usually gives your provider a reason to look at the findings in context rather than drawing an immediate conclusion.
Depending on your situation, your doctor may review laboratory results, compare the findings with previous testing, recommend additional imaging, adjust treatment, or continue monitoring over time.
The next step depends on the cause of the liver changes and how the FibroScan findings fit with the rest of your health information.
FibroScan at ImageCare Radiology
ImageCare Radiology offers FibroScan liver elastography as a noninvasive way to assess liver stiffness and fibrosis associated with several chronic liver conditions. The test can provide useful information for referring physicians without requiring sedation or a surgical procedure.
A Clearer Look at Liver Health
Liver Awareness Month is a useful reminder that you do not need to wait for obvious symptoms before taking liver health seriously.
If your doctor recommends a FibroScan, understanding what the test measures can make the appointment feel much less unfamiliar. The results can provide useful information about liver stiffness and fat while helping your healthcare provider decide whether monitoring, treatment, or further evaluation may be appropriate.
The most useful question to ask afterward is simple: what do these results mean in the context of my overall liver health?
