Abstract：Objective To evaluate the feasibility of low-dose contrast media in aorta angiography by using spiral comput-er tomography .Methods 60 consecutive patients undergoing aorta angiography were allocated into three groups (group A :contrast media 80 ml plus saline 20 ml;group B:contrast media 70 ml plus saline 30 ml;Group C :contrast media 60 ml plus saline 40 ml randomly) .Injection speed was fixed at 5 ml/s .Auto trigger scanning delay time was applied .Image reconstruction was processed when original data were transferred to workstation .The CT values in different anatomic sites ,such as ascending aorta ,descending aorta and aorta crotch ,were collected .Strengthen effect presented by scoring of main branch resolution was evaluated by both an attending doctor and a chief attending doctor .Results No significant differences were noted among three groups ( P value>0 .05) in terms of CT values and subjective scoring .Conclusion Substantial reductions of contrast media dose are achievable at multi-detector angiography of the aorta without compromi-sing image quality and diagnostic performance .
