Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver. MRI has become an important imaging method for non-invasive diagnosis and evaluation of HCC in clinics because of its advantageous aspects, such as its non-radiative nature, superior detection, and qualitative accuracy over CT and ultrasound. Various MRI techniques, including hepatobiliary-specific contrast agents, magnetic resonance elastography, diffusion-weighted imaging, and others, can diagnose HCC or evaluate its malignant biological behavior from different dimensions such as blood supply, cell function, tissue hardness, and water molecule diffusion. This article introduces the current status and prospects of various MRI techniques for HCC diagnosis and evaluation.
肝细胞癌（HCC）是肝脏最常见的原发恶性肿瘤。MRI因其无辐射性以及检出、定性准确性优于CT、超声等多方面优势，已成为当前临床无创性诊断及评估HCC的重要影像手段。多种MRI技术包括肝胆特异性对比剂增强、磁共振弹性成像、扩散加权成像等可从血供、细胞功能、组织硬度、水分子扩散等多维度诊断HCC或评估其恶性生物学行为。现就各种MRI技术在HCC诊断及评估中的应用现状及展望进行介绍。.
