Fatty liver is the most common liver disease. An Estimated 30 Million Americans have fatty liver disease. Fatty liver is a diagnosis of exclusion which means we have to eliminate other types of liver disease.

Get an accurate diagnosis without a liver biopsy with our FibroScan

The gold standard for determining the extent of liver damage was through a liver biopsy. The procedure for a liver biopsy involves inserting a needle in between the ribs over the liver and extracting a small portion of the liver.  That piece is then reviewed under a microscope and the extent of liver injury is evaluated. This is known as Fibrosis which has 4 stages.  Stage 4 is cirrhosis or hardening of the liver. However, we have new technology that is able to place a probe over the liver. The stage of Fibrosis is determined without having to remove a piece of liver. This is non-invasive and causes no bodily harm to the patient. This technology is known as Fibro-Scan and uses transient elastography to measure liver stiffness. We have this technology at Pasadena Liver Center. The procedure takes about 15 minutes. The Patient needs to be fasting for 3 hours. This procedure is covered by most insurance and HMO’s.


We have a dedicated Physician Assistant who has completed over 300 FibroScans.  I believe that this diagnostic tool is more accurate and it causes no bodily harm.  You can schedule your FibroScan 3 times a week by appointment only.

Tuesday, Wednesday, Friday – 8:45am to 10:30am
Tuesday Afternoon – 1:00pm to 2:00pm (Outside referral or no follow up needed)
