Abstract:
Objective To explore MRI features and diagnostic value of primary hepatocellular carcinoma(PHCC).Methods Onehundred and seventy-four patients which were diagnosed as PHCC by MRI were analyzed retrospectively,including signal intensity ofPHCC,pseudocapsules,the sign out of PHCC(such as the tumor thrombi in portal or hepatic vein,lymph nodule in abdomen),and therelationship between them and tumor patterns.The accurate and misdiagnostic rate of MRI in the cases of PHCC proved by pathology were analysed.Results The signal intensity of PHCC was mainly hypointense or slightly hypointense on T_1WI and slightly hyperintense on T_2WI.The accurate rate of MRI in diagnosis of PHCC was 91.42%.The appeared rate of unhomogeneous signal intense of PHCC on T_2WI,thetumor thrombi in portal or hepatic veins and the peudocapsules was of significance in statistics between different type of PHCC.Pseudocapsules were shown better on T_1WI than on T_2WI and fat suppression.Conclusion MRI signal intensity of PHCC is socharacteristic that it has improtant value in diagnosing PHCC.
