FibroScan® is a noninvasive specialized ultrasound machine that measures fibrosis (scarring) and steatosis (fatty change) in your liver.  By sending a pulse of energy to your liver, it gives your medical practitioner information about your liver’s health. Like other ultrasound exams, FibroScan® is painless, easy, and quick. And, because it’s noninvasive, it doesn’t come with the same risks as an invasive biopsy.
