    摘要: The present invention is a technique of, and system for, imaging vascular anatomy over distance considerably greater than the maximum practical field of view of a magnetic resonance imaging system while using substantially one contrast agent injection. The technique and system of the present invention acquires image data of a plurality of image volumes which are representative of different portions of the patient's body. The image data of each image volume includes image data which is representative of the center of k-space. The acquisition of image data which is representative of the center of k-space is correlated with a concentration of contrast agent in the artery(ies) residing in the image volume being substantially greater than the concentration of contrast agent in veins and background tissue adjacent to the artery(ies). This provides preferential enhancement of arteries relative to adjacent veins and background tissue for each acquisition, wherein each acquisition is representative of a different portion of the arterial system (e.g., abdominal aorta, femoral, popliteal, and tibial arteries).
