PURPOSE: The knowledge of celiac trunk vascularization and hepatic arteries' configuration is extremely important in several areas like hepato-biliary pancreatic surgery, as well as in interventional radiological treatment. Our purpose was to evaluate the incidence of anatomic variation of arterial liver vascularization by using MDCTA in a large, homogeneous population. METHODS: Between January 2004 and December 2009, 1,910 patients (1,156 men; mean age, 62.7 years) who underwent MDCT were retrospectively analyzed. Hepatic arterial configuration was classified according to Michels' classification. Image quality was graded according to an ordinal scale. RESULTS: Of the 1,910 examined patients, 281 (15, 67%) were excluded because of sub-optimal image quality. Of the remaining 1,629 patients (986 men; mean age, 61.1 years ± 8 (SD); age range, 19-90 years), anatomic variations were detected in 631 patients (38.73%). CONCLUSIONS: MDCT was useful in analyzing arterial liver configuration and demonstrated the presence of a significant incidence of arterial variants (38.73%) in the examined population.
