What is a FibroScan® and why do I need it?
A FibroScan® is a type of ultrasound that can measure the degree of scarring in your liver. It is a simple, painless test that uses high frequency sound waves. Your doctor recommended that you have this test to help us understand the condition of your liver.
What are the benefits of this scan?
Having a FibroScan® will help determine how much scarring is in your liver. This will help him/her to plan your treatment. It does not have any potential complications or risks and is noninvasive, which means that it does not break the skin or enter your body.
Are there any alternatives to a FibroScan®?
Your doctor will explain any alternatives available to you in detail.
One option is to have a liver biopsy. This is where a small sample of liver tissue is removed with a needle. A liver biopsy has several disadvantages: for example, you need to stay in hospital for several hours after the procedure. It also carries several risks, such as internal bleeding after the biopsy.
Are there any special precautions?
You cannot have a FibroScan® if you are pregnant or have an implantable device, such as a pacemaker or defibrillator. Please speak to your doctor or nurse if you think this applies to you.
What do I need to do to prepare for the scan?
Please avoid drinking alcohol for two weeks prior and do not eat anything for three hours before your FibroScan®. If you need to, you can take small sips of water or clear fluid, but avoid drinking large amounts of fluid. You should continue taking any prescribed medication. You will not need to remove any clothing for the scan, but we will need to expose the right side of your abdomen (tummy). Therefore, we do not recommend that women wear a dress on the day of their test. You will not need to remove any jewelry near the site of the scan, such as a belly button piercing.
What happens before the FibroScan®?
You will need to check in with the receptionist and then take a seat in the waiting area. A Medical Assistant will call you into one of the consulting rooms, where you will be able to ask any questions you have about the FibroScan®. Once you have discussed the scan, and are agreeable to proceeding, you will have the test.
What happens during the scan?
You will be asked to lie on an examination couch and place your right arm above your head. The Medical Assistant will feel your abdomen to find the right place to perform the scan. He/she will place a probe on your abdomen and trigger the probe to start. The sound waves will be sent out from the probe. They will pass through your skin to your liver and bounce back. This will feel like a gentle flick against the side of your skin – it should not hurt.
The scanner measures the time it takes for the sound wave to bounce back. We will repeat this at least 10 times to make sure we get an accurate result. The mean (average) reading is then calculated by the scanner, which will show your doctor the degree of liver stiffness. The scan should take between 10 and 20 minutes to perform.
What happens after the scan?
As soon as the FibroScan® is finished you will be able to either go home or return to work. Your doctor will contact you with the result of your scan in 1 to 2 days.
