A technique to measure absolute arterial blood flow in ml/min has been developed utilizing software programs with high-speed digital recording for the off-line analysis of intra-arterial injections of contrast medium. Measurements of pulsatile flow in a phantom for a physical flow model showed that calculations with the final upgrades were within 10% of known flow, using a recording rate of 30 frames/s, a diameter tubing of 5 mm, and flow rates of 300 to 400 ml/min. Quantitative absolute flow of a peripheral artery such as the internal carotid artery may be obtained during routine cerebral arteriography for comparison with anatomic data.
一种用于测量以毫升/分钟为单位的绝对动脉血流量的技术已经开发出来，该技术利用带有高速数字记录功能的软件程序，对动脉内注射造影剂进行离线分析。在一个用于物理血流模型的体模中对脉动血流进行测量，结果表明，使用30帧/秒的记录速率、5毫米的管径以及300至400毫升/分钟的流速，最终升级后的计算结果与已知血流量的误差在10%以内。在常规脑血管造影过程中，可以获取诸如颈内动脉等外周动脉的定量绝对血流量，以便与解剖数据进行比较。
