Abstract：Objective: Discuss clinical value of magnetic resonance imaging(MRI) of liver dynamic contrast-enhancement and hepatic portal venography in one station examination. Methods: MRI data of 200 hospitalized patients were collected. One hundred and fifty of them undertake one station examination as the experimental group, while the other 50 patients undertake both contrast-enhanced portal vein angiography and liver dynamic contrast-enhancement as the control group. Compare the image quality of the hepatic portal vein, the average waiting time, the total time for MRI, and the total cost. Check the MRI imaging diagnosis of liver cancer, portal vein tumor thrombus, varicose veins in portal hypertension syndrome with surgical and pathological findings and other auxiliary examination results. Results: Compared with the control group, the average waiting time of the experimental group was shortened by 66.67%(P<0.01), the total time for MRI was shortened by 43.84%(P<0.01), and the total cost was lowered by 34.58%. The detection capabilities of the control group were better than those of the experimental group in both inferior mesenteric vein and intra-hepatic branches of hepatic portal vein(P<0.05). There was no statistical difference about the match rate of MRI diagnosis and surgical finding or other auxiliary examination results between experimental group and control group. Conclusion: MRI of liver dynamic contrast-enhancement and hepatic portal vein in one station examination can get the information about liver parenchyma and hepatic portal venous anatomy. It can also lowered the economic burden and time cost.
