两种造影剂在微循环内的流速与红细胞相似，差异无统计学意义（P>0.05）。

The velocity of the red blood cells and the two contrast agents had no significant difference(P>0.05).

机理可能与降脂、降血粘度、改善红细胞变形与降低其聚集能力，以提高椎基底动脉血流速度有关。

The mechanism might be related to reducing cholesterol, reducing blood mucosity, improving red cell transformation and reducing its aggregation to increase blood flow speed of vertebrobasilar artery.
