【 摘 要 】

rho=0.359, all P<0.0001). HS and SS values (>4.81kPa and >7.60kPa) showed better performance than spleen length in predicting the presence of esophageal varices (P=0.0306 and P=0.0064). Diagnostic performances of HS and SS in prediction of high risk varices were comparable to those of DCE-MRI (P=0.1282 and P=0.1371) and the sensitivity was improved when both MRE and DCE-MRI were considered. MRE was highly reproducible with ICC over 0.9.Conclusions: HS and SS are associated with the esophageal varices and showed better performance than spleen length in predicting the presence of esophageal varices, and the diagnostic performance of MRE is comparable to DCE-MRI in prediction of presence of esophageal varices and high risk varices.
