Abnormal Liver Enzymes or Imaging
If earlier liver function tests or an ultrasound showed unexpected results, Velacur can help clarify whether scarring or fat buildup is present and how severe it may be.
AI Summary Velacur is a painless ultrasound scan that measures liver stiffness (fibrosis) and liver fat (steatosis) together. Doctors use it to screen for liver damage and to track conditions such as NAFLD/NASH, especially with abnormal results or metabolic risks. It works like FibroScan, with added automated quality checks. The scan takes about 5 to 10 minutes, with results right away. Abnormal results lead to follow-up with blood work, imaging, or biopsy, not an automatic diagnosis.

Velacur (Ultrasound-Based Elastography)
Medically Reviewed.
Velacur is a non-invasive, ultrasound-based elastography test that measures liver stiffness (fibrosis) and fat content (steatosis). It works on the same shear-wave principle as FibroScan, but adds more detailed imaging and automated quality checks that can make results more reliable and less dependent on the person doing the scan.
Velacur does not replace blood tests or a liver biopsy, but it offers a quick, painless way to screen for liver damage and monitor it over time. Results are read together with liver function tests, other blood work, and your medical history.

Liver Stiffness and Fat Test
What Is Velacur?
Velacur is an imaging-based, non-invasive test used to evaluate liver health. It measures two things at once: liver stiffness, which reflects fibrosis (scarring), and liver fat content, which reflects steatosis (fat buildup). Together these help show both the presence and the severity of fatty liver disease.
The test uses ultrasound-based shear-wave technology combined with an external vibration source and a scanning probe. The device sends mechanical waves through the liver and analyzes how they travel through the tissue — stiffer liver tissue means more fibrosis, while how much the waves are absorbed (attenuation) reflects how much fat is present.
Velacur works on the same underlying principle as transient elastography (the technology behind FibroScan), but it adds more detailed imaging and automated quality checks. This can make results more consistent and less dependent on who is operating the device. Velacur can be used both for initial screening in people who have never been diagnosed and for ongoing monitoring of people already living with NAFLD or NASH.
Velacur at a Glance
- Measures two things at once: liver stiffness (fibrosis) and liver fat content (steatosis).
- Painless and quick — the scan itself takes about 5 to 10 minutes, with results available right away.
- Uses ultrasound-based shear-wave elastography with automated quality checks, similar in principle to FibroScan.
- Suitable for first-time screening and for tracking known NAFLD/NASH, hepatitis B or C, alcohol-related liver disease, or autoimmune hepatitis over time.
- An abnormal result is a reason for follow-up, not an automatic diagnosis — your doctor will interpret it alongside blood work, imaging, or biopsy.
Velacur does not replace blood tests or a liver biopsy; it is a monitoring and screening tool used alongside them.
Reasons for Elastography Testing
Why You Might Be Asked to Take a Velacur Test
Doctors order Velacur to check for liver scarring or fat buildup, often before considering a more invasive test like a biopsy.
Monitoring a Known Liver Condition
People being followed for hepatitis B or C, fatty liver disease (NAFLD/NASH), alcohol-related liver disease, or autoimmune hepatitis may have repeat Velacur scans to track change over time.
Metabolic Risk Factors
Obesity, type 2 diabetes, and high cholesterol raise the risk of fatty liver disease, and Velacur is a painless way to check for early liver changes in people with these risks.
Long-Term Medications That Can Affect the Liver
If you take medication known to affect the liver over the long term, your doctor may use Velacur to monitor for developing fibrosis or steatosis.
Stiffness and Fat Measurements
Understanding Elasticity and Attenuation
Elasticity (Liver Stiffness)
Elasticity measures how stiff your liver tissue is and is used to assess fibrosis. The vibrating pad sends mechanical waves into the liver, and stiffer tissue means the waves travel differently, which points to more scarring.
Attenuation (Fat Content)
Attenuation measures how much the ultrasound waves are absorbed as they pass through the liver. More absorption reflects more fat in the liver tissue, which is used to estimate steatosis.
How Velacur Compares to FibroScan
Velacur and FibroScan both use shear-wave elastography to estimate liver stiffness and fat, and neither test diagnoses a specific disease on its own. Velacur adds more detailed imaging and automated quality checks, which can make results more consistent and less dependent on the person performing the scan.
Velacur Scan Procedure
What to Expect During a Velacur Scan
How the Scan Works
You lie on your back, and a small probe with a vibrating pad is placed under the right side of your back or over your ribs. The device sends painless mechanical waves through the liver and scans it. The entire procedure typically takes about 5 to 10 minutes and needs no sedation, needles, or radiation.
Where It's Done and When You Get Results
The test is usually done in a doctor's office or hospital clinic. Results are generated immediately, so your doctor can often discuss them with you the same day.
A Note on Right Upper Quadrant (RUQ) Pain
Right upper quadrant (RUQ) pain — discomfort felt just below the ribs on the right side, near the liver and gallbladder — is sometimes evaluated using liver imaging like Velacur, though RUQ pain is not a common symptom in early fatty liver disease.

Common Questions
Answers to Common Velacur Questions
What is Velacur?
Velacur is an imaging-based, non-invasive test that measures liver fibrosis (scarring) and steatosis (fat buildup) using ultrasound-based shear-wave technology. It is used to evaluate liver health in people with, or suspected of having, fatty liver disease (NAFLD/NASH).
What are elasticity and attenuation in Velacur results?
Elasticity measures liver stiffness, which is used to assess fibrosis. Attenuation measures how much the ultrasound waves are absorbed, which is used to estimate fat in the liver. Together, they show both scarring and fat accumulation.
How is Velacur different from FibroScan?
Velacur and FibroScan both use shear-wave elastography to measure liver stiffness and fat. Velacur incorporates more detailed imaging and automated quality checks, which can make results more reliable and less dependent on who performs the scan. Neither test replaces blood work or a biopsy.
Does an abnormal Velacur result mean I have severe liver disease?
No. Abnormal results are a reason for follow-up, not an automatic diagnosis. Your doctor may repeat the test or order blood work, imaging, or a biopsy to get a clearer picture before deciding on next steps.
Is the Velacur test painful, and how long does it take?
The scan itself is painless and usually takes about 5 to 10 minutes. You lie on your back while a small probe with a vibrating pad is placed over your liver, and results are available immediately.
