Purpose : To evaluate the MR appearance of the accessory hepatic veins. Materials and Methods : The studyincluded 87 consecutive patients for whom abdominal MR images were obtained. The subjects who had liver lesion orhepatic vascular abnormalities were excluded. Couinaud classified accessory hepatic veins into inferior and middleright hepatic veins. Our major interests were evaluation of the incidence, morphology, and location of theaccessory hepatic vein. Results : Inferior right hepatic vein was demonstrated in 43 out of 87 patients(49%). Themorphology was linear in 35 patients(80.5%), and V-shaped in 8 cases(19.5%). In 40 patients(93%), the inferiorright hepatic vein was located in the posteroinferior aspect of the right lobe. Middle right hepatic vein wasdemonstrated in 7 out of 87 patients(8%). All were single linear in morphology, combined with the inferior righthepatic vein, and located between the right hepatic vein and inferior right hepatic vein. Conclusion : Theaccessory hepatic vein was demonstrated in 49% among the Korean adult population, and was located posteroinferiorportion of the liver, in 93%.
