Abstract: P>Objective To study the types of anatomical variations of hepatic arteries. Methods Hepatic arteries of 64-slice spiral CT scanning data were three-dimensional constructed by using selfdesigned software. The types of anatomical variations were analyzed and classified with Michels’ classification criteria. Results The model presented with realistic profile of hepatic arteries which allowed vivid three-dimensional observation. Of these patients, 40 had normal hepatic arteries (60.61%), 26 had variations (3939%), and 5 had infrequent aberrant hepatic arteries that was not included in Michels’ classification (7.58%). Conclusion Threedimensional model of hepatic arteries can volum
