Every day, doctors use ultrasound, CT scans and MRIs to see inside the body without making an incision. Such tests show size and structure, but they don't show important physical properties such as tissue stiffness, which, for example, is a sign of fibrosis in the liver. But researchers at Mayo Clinic have developed technology that uses sound waves to see if a patient's liver is harder than it should be - if it's developing fibrosis. It's called Magnetic Resonance Elastography (MRE), and it offers a noninvasive alternative to liver biopsy. In this, the first of two podcasts on the subject, Richard Ehman, M.D., a Mayo Clinic Radiologist discusses the MRE and its potential in health care.
