OBJECTIVES: To assess whether gadoxetic acid-enhanced MRI could be used as a prognostic factor for intrahepatic mass-forming @entity201 (IMCCs). METHODS: Forty-one @entity1 with pathologically proven IMCCs who underwent preoperative gadoxetic acid-enhanced MRI were included. The signal intensity of the IMCCs on @entity2763 ( @entity2763 ) MRI was qualitatively analyzed by two radiologists, and categorized into intermediate or hypointense groups. Analysis of clinicopathological prognostic factors and correlations of imaging and histology were also performed. Survival time and time to recurrence (TTR) were analyzed. RESULTS: Of the 41 IMCCs, 23 were in the intermediate group and 18 were in the hypointense group on @entity2763 MRI. IMCCs in the intermediate group were associated with shorter survival time (P   =   0.048) and TTR (P   =   0.002) than the IMCCs of the hypointense group. Only the intermediate group on @entity2763 MRI had a significantly shorter TTR on multivariate analysis (P   =   0.012). The IMCCs of the intermediate group showed a tendency for more @entity5 fibrous stroma than those of the hypointense group (P   =   0.027). CONCLUSIONS: The enhancement of IMCCs on @entity2763 gadoxetic acid-enhanced MRI appears to correlate with @entity5 and outcomes due to the @entity5 fibrous stromal component. Thus, @entity2763 images could be a useful prognostic factor for IMCCs after surgery. KEY POINTS:     The enhancement of IMCCs on @entity2763 correlates with the @entity5 fibrous stroma.     The enhancement of IMCCs on @entity2763 MRI appears to correlate with prognosis.     Gadoxetic acid-enhanced MRI is helpful for predicting prognosis of IMCCs after surgery.
