Abstract:
Objective To explore the value of MR elastography (MRE) and dynamic contrast-enhanced imaging (DCE-MRI) in diagnosis of gastroesophageal varices (GEV) in patients with liver cirrhosis.Methods Totally 59 patients with liver cirrhosis underwent MRE and DCE-MRI.Taking endoscopic examination as the standard,platelet (PLT) count,hepatic stiffness (HS),spleen stiffness (SS) and MR visual score (MR VS) were measured.Values of related parameters in diagnosis of liver cirrhosis GEV were compared with area under the curve (AUC).Results PLT,HS,SS and MR VS were significantly correlated with the grades of GEV with liver cirrhosis (rs =-0.317,0.436,0.682,0.703,all P＜0.05).In the diagnosis of with or without GEV,AUC of SS was higher than that of MR VS,HS,and PLT (AUC=0.880,0.795,0.744,0.635,respectively),and the AUC of SS and PLT had statistically difference (P=0.002).In diagnois of moderate or severe GEV,the AUC of MR VS was higher than that of SS,HS and PLT (AUC=0.893,0.816,0.713,0.665,respectively),and statistical differences of AUC were found between MR VS and HS,as well as between MR VS and PLT (P=0.018,0.002).Sensitivities of MR VS combined with SS in differential diagnosis of liver cirrhosis with or without GEV,liver cirrhosis with moderate or severe GEV were 94.16 ％ and 96.83 ％,respectively.Conclusion MRE is effective in the prediction of GEV with severity and diagnostic value equivalent to DCE-MR.
