摘要目的应用扩散加权成像(DWI)的表观扩散系数(ADC)值,磁敏感加权成像(SWI)的信号强度(SI),钆对比剂增强后的T1加权序列MRI影像评估肝实质期肝纤维化分期的诊断价值。材料与方法 77例病人行3.0 T MRI检查,包括DWI/SWI序列和钆对比剂增强后的T1加权序列。肝纤维化根据活检分期,使用Metavir评分分期:F0(n=21,27.3%);F1
Abstract Objective To assess the value of apparent diffusion coefficient (ADC), signal intensity (SI) of magnetic resonance weighted imaging (SWI) and MRI weighted T1 weighted images of gadolinium contrast agent The diagnostic value of staging. MATERIALS AND METHODS 77 patients underwent 3.0T MRI examination, including DWI / SWI sequence and enhanced T1-weighted sequence of gadolinium contrast agent. Liver fibrosis was based on biopsy staging using the Metavir score staging: F0 (n = 21, 27.3%); F1
