除了经皮活检取得组织学标本检查外,人们已试图应用无创性的影像学检查手段包括磁共振成像(MRI)检查进行肝硬变的诊断。这些检查诊断肝硬变的依据是脾肿大、腹水、静脉曲张、肝脏形态学变化、肝脏结节状外观,超声检查中肝回声不均以及MRI图像上肝信号不均等。本文对持续性肝炎的系列MRI图像进行研究以确定肝炎临床表现加重的指证。 In addition to obtaining histological specimens for percutaneous biopsy, attempts have been made to diagnose cirrhosis using noninvasive imaging techniques including magnetic resonance imaging (MRI). These tests are based on the diagnosis of cirrhosis splenomegaly, ascites, varicose veins, changes in liver morphology, liver nodular appearance, echographic heterogeneity of the liver echo and unequal liver signals on MRI images. In this paper, a series of MRI images of persistent hepatitis were studied to determine the evidence of increased clinical manifestations of hepatitis.
