BACKGROUND Chronic hepatitis C(CHC)is a health burden with consequent morbidity and *** biopsy is the gold standard for evaluating fibrosis and assessing disease severity and prognostic purposes *** altern-atives for liver biopsy such as transient elastography(TE)and diffusion-weighted magnetic resonance imaging(DW-MRI)are critical *** To evaluate TE and DW-MRI as noninvasive tools for predicting liver fibrosis in children with *** This prospective cross-sectional study initially recruited 100 children with CHC virus ***-four children completed the full set of investigations including liver stiffness measurement(LSM)using TE and measurement of apparent diffusion coefficient(ADC)of the liver and spleen using *** biopsies were evaluated for fibrosis using Ishak scoring *** and liver and spleen ADC were compared in different fibrosis stages and correlation analysis was performed with histopathological findings and other laboratory *** Most patients had moderate fibrosis(73.5%)while 26.5%had mild *** had severe fibrosis or *** majority(68.8%)had mild activity,while only 7.8%had moderate *** scores had a significant direct correlation with LSM(P=0.008)and were negatively correlated with both liver and spleen ADC but with no statistical significance(P=0.086 and P=0.145,respectively).Similarly,histopatho-logical activity correlated significantly with LSM(P=0.002)but not with liver or spleen ADC(P=0.84 and 0.98 respectively).LSM and liver ADC were able to significantly discriminate F3 from lower fibrosis stages(area under the curve=0.700 and 0.747,respectively)with a better performance of liver *** TE and liver ADC were helpful in predicting significant fibrosis in children with chronic hepatitis C virus infection with a better performance of liver ADC.
