8Can gadoxetic acid–enhanced magnetic resonance imaging be used to avoid liver biopsy in patients with nonalcoholic fatty liver disease?显示文摘BACKGROUND Nonalcoholic fatty liver disease(NAFLD)is a major cause of liver disease worldwide.The diagnosis of nonalcoholic steatohepatitis(NASH),the most severe form of NAFLD,is crucial and has prognostic and therapeutic implications.However,currently this diagnosis is based on liver biopsy and has several limitations.AIM To evaluate the performance of gadoxetic acid–enhanced magnetic resonance imaging(GA-MRI)in differentiating isolated steatosis from NASH in patients with NAFLD.METHODS In this prospective study,56 patients with NAFLD(18 with isolated steatosis and 38 with NASH)underwent GA-MRI.The contrast enhancement index(CEI)was calculated as the rate of increase of the liver-to-muscle signal intensity ratio from before and 20 min after intravenous GA administration.Between-group differences in mean CEI were examined using Student's t test.The area under the receiver operator characteristic curve and the diagnostic performance of gadoxetic acid–enhanced magnetic resonance imaging were evaluated.RESULTS The mean CEI for all subjects was 1.82±0.19.The mean CEI was significantly lower in patients with NASH than in those with isolated steatosis(P=0.008).Two CEI cut-off points were used:<1.66(94%specificity)to characterize NASH and>2.00(89%sensitivity)to characterize isolated steatosis.CEI values between 1.66 and 2.00 indicated liver biopsy,and the procedure could be avoided in 40%of patients with NAFLD.CONCLUSION GA-MRI is an effective noninvasive method that may be useful for the differentiation of NASH from isolated steatosis,and could help to avoid liver biopsy in patients with NAFLD.Viviane Brandão Amorim Daniella Braz Parente Fernando Fernandes Paiva Jaime Araújo Oliveira Neto Amanda Almeida Miranda Cláudia Cravo Moreira Flávia Ferreira Fernandes Carlos Frederico FerreiraCampos Nathalie Carvalho Leite Renata de Mello Perez Rosana Souza Rodrigues 2020World Journal of Hepatology2020,12,9:0
