Blood Flow Values in the Intact Iliac Artery in Conscious Human Subjects Utilizing Angiocinedensitometry. Proceedings of the International Conference on Bioengineering Held at Cape Town, April 1977

摘要

Blood flow in the iliac arteries was measured by an improved angiographic cinedensitometric method. This consists of cineradiographic recording of radiopaque contrast material injected into the iliac arteries followed by densitometric analysis of the washout phase at two selected sites along the iliac artery. Blood flow values were measured in twenty-four male subjects and eleven female subjects. Blood flow rates in males (604 plus or minus 104 ml/min) were significantly higher than in females (478 plus or minus 54 ml/min), but blood flow velocities were lower in males (21.1 plus or minus 4.1 cm/sec and 27.0 plus or minus 4.5 cm/sec respectively). Differences in hematocrit levels between males and females were found to be partially responsible for the differences in flow velocities. Precision of the technique was determined by 'in vitro' studies and was plus or minus 51.
