1. A method of imaging an artery in a patient using magnetic resonance imaging, comprising,administering a magnetic resonance contrast agent to the patient;

  • collecting image data of an image sequence wherein the image sequence includes;

    image data which is representative of a center of k-space, and image data which is representative of a periphery of k-space, and wherein the image sequence is arranged to collect image data which is representative of the periphery of k-space before and after collecting image data which is representative of the center of k-space; and

    temporally correlating administering the magnetic resonance contrast agent with collecting image data based on the circulation time of the contrast agent so that a concentration of contrast agent in the artery is substantially greater than a concentration of contrast agent in veins and background tissue adjacent to the artery while collecting the image data which is representative of the center of k-space.
