Abstract:
A magnetic resonance imaging system for imaging an artery of a patient using a magnetic resonance contrast agent, the magnetic resonance imaging system comprising:an injection apparatus including, a coiled conduit having a first end, a second end and an inner diameter; a plurality of input ports including a first input port coupled to the first end of the coiled conduit and capable of receiving a first syringe and a second input port capable of receiving a second syringe; one way valves to prevent retrograde fluid flow of fluids that are injected into the first and second input ports; and a locking mechanism, coupled to the second end of the coiled conduit, wherein the locking mechanism is capable of securing the coiled conduit to a catheter; and a magnetic resonance imaging unit to collect image data of an imaging sequence to image the artery, wherein the magnetic resonance imaging unit, in response to an image acquisition signal, collects image data which is representative of the central portion of k-space near the beginning of the imaging sequence and the periphery of k-space thereafter.
