Magnetic Resonance Imaging of Liver Lesions
SUMMARY ∑ With the introduction of breath-hold techniques, magnetic resonance (MR) imaging has become an excellent diagnostic tool for the detection and characterization of benign and malignant liver lesions. Dynamic, gadolinium postcontrast studies as well tissue-specific contrast media highly improve the characterization of liver lesions. Multisection breath-hold techniques enable imaging of the entire region of interest in a single suspended respiration. MR-cholangiopancreatography allows for simultaneous analysis of biliary tree and pancreatic duct. The ability of various MR pulse sequences to display differences between normal and pathologic tissues is the basis of detection and characterization of focal and diffuse liver changes.
