摘要:
磁共振扩散加权成像是一种可反映活体内水分子扩散特征的功能成像方法,能间接反映细胞的密度和细胞膜的完整性及毛细血管灌注情况。介绍了该技术在肝脏病变中的主要应用,并重点介绍其在肝细胞癌、肝纤维化的分期及肿瘤疗效监测中的应用。指出这种无需注射对比剂的技术虽仍有不足,但随着软、硬件的发展,将有广阔的应用前景。
Abstract:Liver failure is a clinical syndrome with severe disorders of liver cells for biosynthesis,detoxication,excretion,and biological transformation,which presents with coagulation disorders,jaundice,hepatic encephalopathy,and ascites.Liver failure progresses rapidly,so the prediction of clinical outcome is significant for the diagnosis and treatment.In recent years,there have been numerous reports on the prediction of clinical outcome in patients with liver failure.The study and application of serological and comprehensive models are reviewed,which provides a reference for the rational therapy for liver failure patients.
