| 摘 要： | 目的利用西门子Perspective 128层螺旋CT探讨触发阈值为30HU联合多期双流注射45ml对比剂对大体重人群(90.0±7.35)kg行头颈部联合CTA扫描的可行性。方法将60例符合条件的行头颈联合CTA扫描患者随机分成实验组(A组)和对照组(B组),每组30例。A组注射对比剂45ml及生理盐水55ml,并将触发阈值设为30HU,B组注射对比剂55ml及生理盐水45ml,并将触发阈值设为100HU,两组间其余扫描参数设置相同。比较两组间图像质量。结果 A组主动脉弓、双侧颈总动脉及颈内动脉、双侧大脑中动脉强化程度低于B组,差异具有统计学意义(P<0.05);A组头颈部静脉显影情况主观评分好于B组,差异具有统计学意义(P<0.05);两组间头颈部各段动脉成像效果主观评价无统计学差异(P>0.05)。结论使用45ml对比剂对大体重人群行头颈部联合CTA扫描是可行的。
