Continuously moving table MRA enables the acquisition of seamless large FOV data with a significantly streamlined workflow. In contrast enhanced MRA the total acquisition time is conventionally restricted to the arterial time window. In the current work, continuously moving table data acquisition and reconstruction was combined with k-space segmentation such that the central region of k-space is acquired during the first-pass and the peripheral region was acquired during the late phase of the contrast agent. This method was successfully evaluated with 5 patients with known PAOD who underwent moving table MRA. The spatial resolution was increased while avoiding venous overlay.
