Liver Masses: What Physicians Need to Know About Ordering and Interpreting Liver Imaging

Purpose of Review This paper reviews diagnostic imaging techniques used to characterize liver masses and the imaging characteristics of the most common liver masses. Recent Findings The role of recently adopted ultrasound and magnetic resonance imaging contrast agents will be emphasized. Summary Contrast-enhanced ultrasound is an inexpensive exam which can confirm benignity of certain liver masses without ionizing radiation. Magnetic resonance imaging using hepatocyte-specific gadolinium-based contrast agents can help confirm or narrow the differential diagnosis of liver masses.
