Characterization of liver masses detected by imaging studies plays a vital role in planning initial management and follow up in patients. Magnetic resonance imaging (MRI) of the liver has evolved significantly over the last several years, in large part due to improved gradients, fast imaging techniques, and better understanding of optimal use of contrast agents. MRI has become the modality of choice for accurate characterization of focal liver lesions. Further, MRI rivals and may soon surpass the sensitivity of intraoperative ultrasound and computed tomographic arterial portography (CTAP) for detection of liver abnormalities. This paper will discuss the current techniques used in liver MRI as well as the role of liver- specific contrast agents. In addition, the MR imaging features of the most common liver lesions are reviewed to allow the reader to accurately and confidently diagnosis focal liver lesions.Wednesday, 16 Jan 2002 23:40:10 GMT
