Abstract PDF: Magnetic resonance imaging (MRI) has a strongpoint in the detection and characterization of hepatic tumor as it provides multiparametric information. With active implementation of a surveillance program for high-risk hepatocellular carcinoma patients, early hepatocellular carcinoma or cholangiocarcinoma with atypical vascular pattern is being detected with increasing frequency. Therefore, in daily practice, it is challenging to differentiate atypical HCC from dysplastic nodule, hypervascular cholangiocarcinoma and focal nodular hyperplasia-like nodules. Gadoxetic acid and diffusion-weighted imaging has opened new horizons for liver MRI with promising results for liver lesion detection and characterization. Combined both has the potential to be robust liver MR protocol in that it is targeting three processes of hepatic carcinogenesis-hemodynamic changes, hepatocyte function, and tissue diffusivity. In that sense, liver MRI has the potency to fulfill the above two-fold requirement in a more satisfactorily than other liver imaging modalities.

Imaging Technique of Liver MRI: Young Kon Kim; Journal of the Korean Liver Cancer Study Group. 2012;12(1):1-4. Published online February 28, 2012

Abstract PDF: Magnetic resonance (MR) imaging provides exquisite, versatile, and unique soft tissue contrast, which allows for an effective evaluation of a wide range of liver disorders. A careful selection of imaging strategies can yield a comprehensive assessment of the liver in a reasonable examination time. Recent advances in MR hardware and software allow for rapid acquisition times that can reduce many of motion artifacts that previously posed limitations to abdominal MR imaging. The ability to obtain artifact-free images with sufficient contrast-to-noise ratios across a broad range of techniques is now feasible with rapid scanning. Recently, the use of 3T in liver imaging allows further improvement in image quality.
