摘要
This invention is a method of imaging arteries distinctly from veins using nuclear magnetic resonance imaging in combination with intravenous administration of a magnetic resonance contrast agent. The contrast agent is intravenously injected in such a way that the arterial contrast concentration is substantially higher than the venous and background tissue concentration for a sufficiently long period of time to acquire the magnetic resonance image. The injection site of the contrast agent is chosen such that it is in a vein which is remote from the artery of interest. The magnetic resonance contrast agent may be intravenously infused at a variable infusion rate.
