1. A method of imaging arteries in a patient using a magnetic resonance imaging system having an imaging coil, wherein the arteries including a first artery which is located in a first image volume and a second artery in a second image volume, the method comprising:

  • administering a contrast agent to the patient;

    positioning the patient in a first location in the imaging coil;

    collecting image data of the first image volume including collecting image data which is representative of a center of k-space while a concentration of the administered contrast agent in the first artery is substantially higher than a concentration of the contrast agent in veins and background tissue adjacent to the first artery and while the patient is in the first location;

    re-positioning the patient in a second location in the imaging coil; and

    collecting image data of a second image volume, including collecting image data which is representative of a center of k-space while a concentration of the administered contrast agent in the second artery is substantially higher than a concentration of the contrast agent in veins and background tissue adjacent to the second artery and while the patient is in the second location.
