用抽签法将60例头颈动脉成像的患者随机分为常规方案组和优化方案组,各30例,分别采用常规方案和优化方案成像,对所形成图像进行评价.优化方案组能有效消除头臂静脉高密度伪影干扰、显著提高颈部动脉起始段及颅内动脉的显示能力,两组间差异有统计学意义.该优化方案可行,是比较理想的64层CT头颈动脉成像方案.

Sixty patients who underwent brain and neck CT angiograpby (CTA) were randomly divided into two groups: conventional protocol group and optimizing protocol group with 30 in each. The images were evaluated by two radiologists independently. The images of optimizing group avoided the artifact disturbance of the brachiocephalic vein effectively and greatly improved the imaging quality of arteria carotis communis and arteria vertebralis initial segment. Compared with the conventional group the differences were statistically significuat(P <0.05). The optimization of 64-MDCT brain and neck CTA is feasible and effective.
