Magnetic resonance arteriography with dynamic,intravenous injection of contrast agents

摘要

This invention is a method of imaging arteries distinctly from veins and background tissue using nuclear magnetic resonance imaging in combination with administration of a paramagnetic contrast agent. The contrast agent is intravenously injected in a vein remote from the artery of interest 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 contrast agent is infused at a variable or constant rate. The rate is matched with the mapping of k-space so that the maximum injection rate occurs during acquisition of the centre of k-space.
