1. A method of imaging arteries in a patient using a magnetic resonance imaging system and a magnetic resonance contrast agent, wherein the arteries include a first artery which is located in a first image volume and a second artery which is located in a second image volume, and wherein the magnetic resonance contrast agent is administered to the patient via substantially one injection, the method comprising:

  • positioning the patient at a first location to define a first field of view which encompasses the first artery, wherein the first artery is in an abdomen of the patient;

    collecting magnetic resonance image data of the first image volume, wherein at least a portion of the image data of the first image volume is collected during an arterial phase of contrast enhancement of the first artery;

    positioning the patient at a second location to define a second field of view which encompasses the second artery, wherein the second artery is in at least one of a pelvis, leg or foot of the patient; and

    collecting magnetic resonance image data of the second image volume, wherein at least a portion of the image data of the second image volume is collected during an arterial phase of contrast enhancement of the second artery.
