Liver transient elastography (FibroScan) is a non-invasive ultrasound tool for assessing liver fibrosis or scarring by measuring liver stiffness (LSM). Compared with liver biopsy, FibroScan provides immediate results and is a painless, short (3 mins), simple procedure to perform. In some studies FibroScan reports have correlated well with liver biopsy results of fibrosis and cirrhosis, and with Ferriscan, ferritin and liver function tests.
