摘要
目的 介绍 1995年国际肝病工作组关于肝硬变结节的分类标准 ,总结与病理学特征相关的各种肝结节的影像学表现 ,并探讨各种影像学检查方法的诊断价值。方法 用超声、CT、MRI、血管造影性CT等各种影像学检查方法。结果 在肝硬变背景基础上肝癌的发生、发展 ,沿循从再生结节、低度非典型性结节、高度非典型性结节到小肝癌 (SHCC)、大肝癌的逐步演进过程 ,在此过程中同时伴有结节内血流供应和灌注的相应变化。结论 现代影像学检查技术的发展为肝内各种结节的检出、定性和鉴别诊断提供了多种十分有效的方法 ,为各类肝结节 ,特别是早期小肝癌结节的诊断、治疗创造了有利条件。
Objective To introduce the new nomenclature scheme of the International Working Group (1995) on hepatic nodules, and summarize the imaging features of various hepatic nodules in light of their pathological characteristics, and evaluate the diagnostic values of various imaging facilities.Methods Ultrasound, computed tomography(CT), magnetic resonance imaging(MRI), and angiographic CT were reviewed and introduced.Results Many of these types of hepatic nodules play a role in the de novo and stepwise carcinogenesis of hepatocellular carcinoma(HCC) in the following steps: regenerative nodule, low grade dysplastic nodule, high grade dysplastic nodule, small HCC, and large HCC. Accompanying such transformations, there are significant alterations in the blood supply and perfusion of these hepatic nodules.Conclusion Modern state of the art medical imaging facilities can not only delineate and depict these hepatic nodules, but also provide important clues for the characterization of focal hepatic lesions in most cases, thus facilitating the early detection, diagnosis and management of HCC in its early stage.
