FibroScan is a non-invasive diagnostic device used to measure liver scarring or fibrosis caused by a number of liver diseases. It is a type of liver elastography that measures liver stiffness and fatty changes in the liver. The FibroScan is a special ultrasound technology that measures the speed of a shear wave as it travels through the liver, which can be used as an aid to clinical management of liver disease. The procedure is quick, painless, and easy, and provides a non-surgical alternative to the traditional liver biopsy to assess liver damage. FibroScan is used to help diagnose or monitor the progression of diseases affecting the liver, such as cirrhosis or Hepatitis C. The exam is performed on an empty stomach, and the patient should not eat anything for at least three hours prior to the examination. The results are immediate and can be interpreted by a physician according to the patients history and underlying disease. FibroScan is a helpful technology that allows patients and doctors to find out the state of liver health quickly and easily.
