ABSTRACT
Objective To analyze the anatomic variation of the portal vein based on magnetic resonance angiography using THRIVE sequence in one-stop examination of the liver.Methods Reconstructed three-dimensional images of 648 cases of hepatic portal vein acquired by THRIVE sequence were analyzed.Anatomic variation of the hepatic portal vein was investigated and the diameters of main portal vein (MPV), splenic vein (SV), superior mesenteric vein (SMV) and inferior mesenteric vein (IMV) were measured.Results (1)Four types of different variations of intrahepatic portal vein were observed, with normal type accounting for 79.2% (514/648), type Ⅰ 8.3% (54/648), type Ⅱ 9.0% (58/648) and type Ⅲ 3.4% (22/648), respectively.(2)Four types of different variations of extrahepatic portal vein were also observed, with type Ⅰ accounting for 37.4% (167/447), type Ⅱ 20.4% (91/447), type Ⅲ 36.2% (162/447) and other 6.0% (27/447), respectively.(3)Diameter of MPV, SV, SMV and IMV were (14.03±2.44) mm, (9.51±2.40) mm, (11.14±1.99) mm and (6.01±0.78) mm, respectively.Conclusion It is feasible to analyze anatomic variation in the hepatic portal vein using reconstructed three-dimensional images acquired by THRIVE sequence in one-stop examination of the liver.
