Abstract: Objective To investigate the effect of the choice of the different models of venous indwelling needle on coronary flash dual-source computed tomography (CT) angiography.Methods 120 patients were randomly divided into three groups (40 cases in each group) who were selected to use 18G,20G,22G indwelling needle.They underwent CT coronary imaging.We measured the CT value of left and right coronary artery opening,right vein opening plane and the right ventricular cavity.We also compared the pain of patients during puncture.Results 120 cases were completed inspection.There was significant difference in the strengthen value of left and right coronary artery and CT value of the right ventricle cavity between 18G and 20G.The difference in the strengthen value of left and right coronary artery and CT value of the right ventricle cavity between 18G and 22G was also significantly different.There was no significant difference in all monitoring points between 20G and 22G.Three types of right coronary vein were not statistically significant.Conclusions Model 20G indwelling needle get the best flash dual-source CT image and better patients' acceptance.
