Preliminary Clinical Study of MRI in Primary Hepatic Cancer with Different Differentiation / 现代生物医学进展

ABSTRACT

Objective:To study parameters of MRI image in different tissue differentiation,cell type of primary liver cancer.Methods:The pathological results and MRI data of regeneration nodules (27),hepatocellular carcinoma (HCC) (81 total;15,highly differentiated;40,moderately differentiated;26,low-grade differentiation),intrahepatic cholangiocarcinoma (ICC) (20) were retrospectively analyzed and compared To compare the difference of ADC values,strengthen degree among the regeneration nodules,HCC and ICC,and among HCC tissue differentiation.Results:Most cases of primary liver cancer can be accurately diagnosed by conventional MRI combined with LAVA.there are statistically significant differences of ADC values among regenerative nodules,HCC,ICC (P＜0.01),and among highly,moderately,poorly differentiated HCC groups (P＜0.01).But there is not actual clinical significance of the ADC values between moderately and poorly HCC.there is no statistically significant difference of the ADC values between highly differentiated HCC and ICC (P=0.27).Conclusion:Conventional MRI combining with DWI,LAVA can help distinguish the primary liver cancer differentiation degree and the cell type.
