Abstract: Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver.The incidence and mortality rates were ranked the sixth and three respectively in all kinds of tumors.Liver resection and liver transplantation has achieved remarkable curative effect in the treatment of early of HCC,but the recurrence is still an important problem to be solved.In HCC patients,local resection and liver transplantation after 5 years,the recurrence rate wasere 70％ and 35％,respectively.The invasiveness of tumor is different,and the recurrence rate is also different.Microvascular invasion (MVI) as a marker of tumor invasion has been widely used in the diagnosis of HCC.Some scholars believe that MVI imay bes the first step in the liver or systemic metastasis of liver cancer,if we can predicted the MVI before surgery,it will play a positive role in making treatment programs,because in order to reduce the recurrence rate,anatomic resection of and extended resection range is recommended.Advances in magic radiological technology have made made it possible to diagnose MVI before surgery.In this paper,CT,MRI,PET and ultrasound in the diagnosis of MVI would be introduced.
