Appearance and MRI findings of hepatic perivascular lucency in different liver diseases
Objective To describe the pathological mechanism and MRI findings of PVL,discuss its association with the occurrence of the same liver diseases,and evaluate the clinical significance of PVL.Methods A total of 197 patients with liver-related diseases admitted to the Third People's Hospital of Jiujiang from January 2019 to January 2020 were retro-spectively analyzed,and according to the disease type,they were divided into chronic hepatitis B group(111 cases),cirrhosis group(57 cases),and liver tumor group(29 cases).The MRI manifestations of PVL in the three groups were observed,and the MRI plain scan and enhanced image data of the upper abdomen of the patients were studied,and different liver diseases and different levels of PVL were analyzed.Results The PVL detection rate was 32.4％in patients with chronic hepatitis B,31.0％in patients with liver tumor,and 40.4％in patients with cirrhosis.The incidence of PVL in patients with cirrhosis did not change with the increase of cirrhosis grading score(P＞0.05).The incidence of PVL in patients with hilar obstruction was higher than that in patients with uninvaded hilar area,and the difference was statistically significant(P＜0.05).Con-clusion The MRI distribution and manifestations of PVL in different liver diseases have corresponding characteristics,which has reference value for the evaluation of the severity and prognosis of chronic hepatitis B disease,as well as the diagnosis of liver tumor invading the hepatic portal region.
