MAGNETIC RESONANCE ARTERIOGRAPHY WITH DYNAMIC INTRAVENOUS CONTRAST AGENTS

摘要

This invention is a method of imaging arteries distinctly from veins usingnuclear magnetic resonance imaging in combination withintravenous administration of a magnetic resonance contrast agent. Thecontrast agent is intravenously injected in such a way that thearterial contrast concentration is substantially higher than the venous andbackground tissue concentration for a sufficiently long period oftime to acquire the magnetic resonance image. The injection site of thecontrast agent is chosen such that it is in a vein which is remotefrom the artery of interest. The magnetic resonance contrast agent may beintravenously infused at a variable infusion rate.
