Objective: To investigate the three-dimensional reconstruction methods of celiac artery using 64-slice spiral CT data and its anatomical data. Methods: Three-dimensional reconstruction was performed by Mimics software with 64-slice spiral CT data of 120 cases. Each model of celiac artery and its branches was evaluated according to presentation rate, branch type, orifice, course and length. Results: The three-dimensional model of the celiac artery displayed vivid three-dimensional structures. The presentation rate of the celiac artery and its branches are as follows: 100% of the celiac, common hepatic, splenic and gastroduodenal arteries, 78.3% of the left gastric artery, 98.3% of the proper hepatic artery, 79.2% of the left hepatic artery, 95% of the right hepatic artery. The classical configuration of the celiac artery was detected in 89.2% and the mean length of this type was 2.76cm. The celiac artery arose at the level between the 12th thoracic vertebra and 1st lumber vertebra in 96.7% and its course showed many styles, mostly toward right in 83.3%. Conclusion: Three-dimensional reconstruction of celiac artery based on 64-slice spiral CT may really response the structure and anatomic data, which can provide digital anatomic atlas for the anatomy teaching, play a guiding role in the intervention and offer a distinct model for virtual operations.
