Abstract:
Objective To discuss the MRI manifestations of primary biliary cirrhosis in order to improve the diagnosis.Methods The MRI manifestations of primary biliary cirrhosis proved by pathology and clinical diagnosis in 5 patients were analyzed retrospectively.The patients underwent plain T1 WI,T2 WI,DWI (b=0,800 s/mm2 )and magnetic resonance cholangiopancreatography.Results MRI showed the thickening and smooth portal vein wall with hyperintensity on T2 WI in 3 patients.Theperiportal halosign with hypointensity on T1 WI and hyperintensity on T2 WI was observed around portal venous branches in 3 patients.Unclear 2-3 grades of intrahepatic bile ducts were found in 4,and narrow lumens of intrahepatic and extrahepatic bile ducts were also found in 3.Periportal hyperintensity on T2 WI and DWI and enlarged lymph nodes in abdomen were also revealed in 5 .Mild ascites and shrinking gallbladder volume were showed in 3.Splenomegaly was showed in 4.Conclusion MR manifestations of periportal hyperintensity on T2 WI,periportal halosign,splenomegaly,unclear 2-3 grades of intrahepatic bile duct and narrow lumen of intrahepatic and extrahepatic bile duct may paly an important role in diagnosis of primary biliary cirrhosis.
