Abstract：Objective To investigate the head bone removal technique effect of dual-energy computed tomography angiography ( DE-CTA) of the neck in comparison with body bone removal technique.Methods Sixty-six subjects underwent carotid DE-CTA in our hospital from August 1, 2014 to October 31, 2014.Their datasets were post-processed by head bone removal tech-nique and body bone removal technique, respectively.The Rank-sum test was used to compare the effect of difference between the two automatic bone removal techniques.Results Four hundred and twenty-nine arterial branches of the neck were demonstrated by body bone removal mode, and all 8 arterial branches of the neck were revealed in 43 cases.Five hundred and twenty-four arte-rial branches were displayed by head bone removal mode, and all 8 arterial branches were seen in 63 cases.There was a signifi-cant difference between the two groups ( P <0.001).Conclusion Head bone removal mode is superior to body bone removal mode in DE-CTA of the neck.
