Liver Imaging Reporting and Data System: an expert consensus statement

Khaled M Elsayes et al. J Hepatocell Carcinoma. .

Abstract

The increasing incidence and high morbidity and mortality of hepatocellular carcinoma (HCC) have inspired the creation of the Liver Imaging Reporting and Data System (LI-RADS). LI-RADS aims to reduce variability in exam interpretation, improve communication, facilitate clinical therapeutic decisions, reduce omission of pertinent information, and facilitate the monitoring of outcomes. LI-RADS is a dynamic process, which is updated frequently. In this article, we describe the LI-RADS 2014 version (v2014), which marks the second update since the initial version in 2011.

Keywords: cirrhosis; hepatocellular carcinoma; hyperenhancement washout; imaging; reporting.

HCC in a 57-year-old man with chronic HCV. Notes: Axial post-contrast T1-weighted MR images in arterial (A) and delayed phase (B) demonstrate a well-circumscribed oval lesion measuring 2.5 cm in maximal dimension exhibiting homogeneous hyperenhancement in the arterial phase (arrow) with washout and enhancing capsule in the delayed phase (arrow). This lesion is category LR-5. See Table 2 for LI-RADS classifications. Abbreviations: HCC, hepatocellular carcinoma; HCV, hepatitis C virus; MR, magnetic resonance.

HCC in a 67-year-old man with alcoholic cirrhosis. Notes: Axial post-contrast T1-weighted MR images in arterial (A), delayed phase (B), axial T2-weighted (C), and diffusion weighted (D) MR images demonstrate an infiltrative mass (asterisk) with ill-defined margins, exhibiting heterogeneous enhancement in the arterial phase, washout in the delayed phase with moderately increased signal intensity on T2-weighted and diffusion restriction on diffusion-weighted images. There is soft tissue noted within the left portal vein (arrow) exhibiting all signal characteristics and contrast enhancement similar to the tumor, representing LR-5V. See Table 2 for LI-RADS classifications. Abbreviations: HCC, hepatocellular carcinoma; MR, magnetic resonance.
