Abstract
High-speed biplane angiography is used to determine the path and velocity of microdroplets of contrast material in three dimensions. By allowing more accurate determination of detailed blood flow in feeding vessels and draining veins of cerebral arteriovenous malformations than available with standard angiography, the new method offers the potential for more accurate treatment and further study of neurovascular/cerebrovascular hemodynamics. The first study of the method is presented.
摘要
高速双平面血管造影术用于三维确定造影剂微滴的路径和速度。与标准血管造影相比，这种新方法能更准确地测定脑动静脉畸形供血血管和引流静脉中的详细血流情况，为更精确的治疗以及神经血管/脑血管血流动力学的进一步研究提供了可能。本文展示了该方法的首次研究。
