MRI for hepatocellular carcinoma and the role of abbreviated MRI for surveillance of hepatocellular carcinoma

Abstract

IntroductionHepatocellular carcinoma (HCC) constitutes the majority of liver cancers and significantly impacts global cancer mortality. While ultrasound (US) with or without alpha‐fetoprotein is the mainstay for HCC surveillance, its limitations highlight the necessity for more effective surveillance tools. Therefore, this review explores evolving imaging modalities and abbreviated magnetic resonance imaging (MRI) (AMRI) protocols as promising alternatives, addressing challenges in HCC surveillance.Areas CoveredThis comprehensive review delves into the evaluation and challenges of HCC surveillance tools, focusing on non‐contrast abbreviated MRI (NC‐AMRI) and contrast‐enhanced abbreviated MRI protocols. It covers the implementation of AMRI for HCC surveillance, patient preferences, adherence, and strategies for optimizing cost‐effectiveness. Additionally, the article provides insights into prospects for HCC surveillance by summarizing meta‐analyses, prospective studies, and ongoing clinical trials evaluating AMRI protocols.Expert OpinionThe opinions underscore the transformative impact of AMRI on HCC surveillance, especially in overcoming US limitations. Promising results from NC‐AMRI protocols indicate its potential for high‐risk patient surveillance, though prospective studies in true surveillance settings are essential for validation. Future research should prioritize risk‐stratified AMRI protocols and address cost‐effectiveness for broader clinical implementation, alongside comparative analyses with US for optimal surveillance strategies.
