The typical histological features of chronic hepatitis and cirrhosis are variable degrees of hepatocellular necrosis and inflammation (activity or grade of disease), fibrosis (stage of disease), and associated fat and iron deposition. These features influence the liver's appearance and must be assessed separately by imaging biomarkers in order to be clinically useful. Hepatic morphologic alterations and features of portal hypertension identify most cases of established cirrhosis. Nowadays, research is focused on developing ways to improve detection of early and intermediate stages of fibrosis as well as hepatocyte dysfunction. Even more, most imaging-related measurements are subject to complex interactions and are influenced by different pathologic processes, such as fatty infiltration, edema, necrosis and iron accumulation. METHODS AND RESULTS: MR experience throughout the last 15 years at the Dr Peset University Hospital is reviewed. CONCLUSION: Nowadays, several biomarkers have been developed to grade the liver status in cirrhosis. This review will focus on these topics.
慢性肝炎和肝硬化的典型组织学特征包括不同程度的肝细胞坏死和炎症(疾病活动度或分级)、纤维化(疾病分期)以及相关的脂肪和铁沉积。这些特征会影响肝脏的外观,为了具有临床实用性,必须通过成像生物标志物分别进行评估。肝脏形态学改变和门静脉高压特征可识别大多数已确诊的肝硬化病例。如今,研究集中在开发改善早期和中期纤维化以及肝细胞功能障碍检测的方法。此外,大多数与成像相关的测量都受到复杂相互作用的影响,并受到不同病理过程的影响,如脂肪浸润、水肿、坏死和铁蓄积。
回顾了佩塞特大学医院过去15年的磁共振成像经验。
如今,已开发出多种生物标志物来对肝硬化的肝脏状态进行分级。本综述将聚焦于这些主题。
