Abstract：Objective: Using multi-detector row CT angiography to measure the value of normal dimension of cervicocerebral arterial trunks and their main branches. Methods: One hundred and twenty adults performing multi-detector row CTA with no cervicocerebral arterial diseases and blood flow abnormalities, were divided into 3 groups according to their age(<40y, 40~60y, >60y), with 40 cases in each group(20 cases for each gender). Images were taken to the workstation and measurements were done on 3D Images. All the results were statistically analyzed. Results: Results from measurements had shown that dimensions of 20 branches(60.6%) had significant difference between two genders(P<0.05). Dimensions of two genders’ ACoA, male’s PCoA, female’s CCA, ECA, BCA and LSCA had significant difference in different age group(P<0.05). Conclusion: Cervicocerebral artery trunks and their branches can be clearly shown by multi-detector row CTA. Measurement of the normal dimension of cervicocerebral artery provides valuable imaging information in the diagnosis of cervicocerebral arterial diseases and diseases that can produce morphologic change of cervicocerebral artery.
