<正>Objective: To evaluate the enhancement characteristics of the hepatic parenchyma during scanning with computed tomography （CT） during splenoportography （CTSP）. Methods: Thirty patients refferred for CTSP were included in the study. Attenuation was measured at different time after contrast medium injection

and time-attenuation curves were created. Enhancement characteristics were evaluated

and the parenchyma-to-tumor difference of attenuation were compared. Results: CTSP led to high parenchymal enhancement. The highest enhancement value in the left lobe was （218. 0±53. 2） Hu and （246. 0±60. 2） Hu in the right lobe. The difference between the right and left lobes was statistically significant （P<0. 05）; The parenchyma-to-tumor difference of （65. 3±25. 6） Hu was observed during scanning after injection. Conclusion: The high levels of liver parenchymal enhancement and parenchyma-to-lesion contrast can be achieved within the scanning time with CTSP.
