Liver imaging: it is time to adopt standardized terminology

Area of Science:

• Radiology
• Hepatology
• Medical Imaging

Background:

• Inconsistent terminology in liver imaging research hinders progress in hepatocellular carcinoma (HCC) management.
• A unified lexicon is needed to standardize communication among researchers, educators, and clinicians.
• The American College of Radiology (ACR) Liver Imaging Reporting And Data System (LI-RADS) aims to address this challenge.

Purpose of the Study:

• To establish a single, universal liver imaging lexicon.
• To promote standardized terminology for research, education, and clinical care in HCC risk assessment.
• To facilitate consistent communication and improve patient management.

Main Methods:

• Development of a consensus document by the ACR LI-RADS Steering Committee, LI-RADS Lexicon Writing Group, and LI-RADS International Working Group.
• Creation of a standardized lexicon for liver imaging.
• Guidelines for adoption in research, education, and clinical practice.

Main Results:

• A universal liver imaging lexicon has been established.
• The lexicon is intended for use in both the LI-RADS population (at risk for HCC) and the general population.
• Anticipated benefits include improved research, education, and clinical care.

Conclusions:

• Universal adoption of the LI-RADS lexicon will standardize liver imaging terminology.
• Encourages authors, reviewers, and radiologists to utilize the LI-RADS lexicon for consistency.
• Aims to enhance the quality and reliability of liver imaging interpretation and reporting.
